The Ust’-Ishim man’s genome suggests he belonged to a group of people who lived after the African exodus, but before the split between Europeans and Asians.

By comparing the Ust’-Ishim man’s long stretches of Neanderthal DNA with shorter stretches in living humans, Dr. Paabo and his colleagues estimated the rate at which they had fragmented. They used that information to determine how long ago Neanderthals and humans interbred.

Humans and Neanderthals interbred 50,000 to 60,000 years ago, according to the new data.

The findings raised questions about research suggesting that humans in India and the Near East dated back as far as 100,000 years ago. Some scientists believe that humans expanded out of Africa in a series of waves.

the new study offered compelling evidence that living non-Africans descended from a group of people who moved out of Africa about 60,000 years ago.Any humans that expanded out of Africa before then probably died out, Mr. Stringer said.

we miss the real question of why there is a systemic, historical difference in the way police treat blacks versus whites.

he came to see black respectability—the idea that, to succeed, African-Americans must stoically prevail against the odds and be “twice as good” as white people to get the same rights—as deeply immoral.

For Coates, true equality means “black people in this country have the right to be as mediocre as white people,” he says. “Not that individual black people will be as excellent, or more excellent, than other white people.”

he cites research that in 1860 slaves were the largest asset in the US economy. “It is almost impossible to think of democracy, as it was formed in America, without the enslavement of African-Americans,” he says. “Not that these things were bumps in the road along the way, but that they were the road.”

Another term for that road is “white supremacy.” This refers not so much to hate groups, but, as Coates defines it, a system of policies and beliefs that aims to keep African-Americans as “a peon class.”

To be “white” in this sense does not refer merely to skin color but to the degree that someone qualifies as “normal,” and thus worthy of the same rights as all Americans

The pool where all these ideas eventually arrive is a question: “How big-hearted can democracy be?” he says. “How many people can it actually include and sustain itself? That is the question I’m asking over and over again.”

it is a question of empathy. Are humans capable of forming a society where everyone can flourish?

there was the coverage of Michael Brown (or Jordan Davis, or Renisha McBride, or Eric Garner): unarmed African-Americans killed by police or others under controversial circumstances. In each case, the storyline was that these horrific encounters were caused either by genuine provocation, or by race-fueled fear or hatred. Either way, they were stories of personal failings.

When an event becomes news, there is often an implication that it is an exception—that the world is mostly working as it should and this event is newsworthy because it’s an aberration. If the race-related stories we see most often in the media are about personal bigotry, then our conception of racism is limited to the bigoted remarks or actions—racism becomes little more than uttering the n-word.

He is no soothsayer, telling people what to think from on high, but rather is refreshingly open about what he doesn’t know, inviting readers to learn with him. Coates is not merely an ivory-tower pontificator or a shiny Web 2.0 brand. He is a public intellectual for the digital age.

a lack of historical perspective in the media’s approach to race. “Journalism privileges what’s happening now over the long reasons for things happening,” he says. “And for African-Americans, that has a particular effect.”

Even the very existence of racism is questioned: A recent study published by the Association of Psychological Science has shown that whites think they are discriminated against due to race as much if not more than blacks.

“So when you’re talking about something like institutional racism and prejudice, how do you talk about that as an objective reality?”

Coates’ strength is in connecting contemporary problems to historical scholarship. “I think if I bring anything to the table it’s the ability to synthesize all of that into something that people find emotionally moving,” he says. The irony of the reparations piece, as unoriginal as it may have been to scholars, is that it was news to many people.

Reporting on race requires simultaneously understanding multiple, contradictory worlds, with contradictory narratives. Widespread black poverty exists; so do a black middle class and a black president

Progress is key to the myth of American Exceptionalism, and the notion that America is built on slavery and on freedom are discordant ideas that threaten any simple storyline. Coates, together with others who join him, is trying to claim the frontier of a new narrative.

reading Coates is like building a worldview, piece by piece, on an area of contemporary life that’s otherwise difficult to grasp.

“To come and tell someone may not be as effective in convincing them as allowing them to learn on their own. If you believe you come to a conclusion on your own, you’re more likely to agree.”

It’s brave to bare yourself intellectually on the Web, and to acknowledge mistakes, especially when the capital that public intellectuals appear to have is their ability to be “right.”

Coates is equally demanding of his followers. Online he is blunt, and willing to call people out. He cares enough to be rigorous

despite being a master of online engagement, Coates insists he does not write for others, an idea he explained in a recent post: “I have long believed that the best part of writing is not the communication of knowledge to other people, but the acquisition and synthesizing of knowledge for oneself. The best thing I can say about the reparations piece is that I now understand.”

To him, it’s an open question whether or not America will ever be capable of fostering true equality. “How big-hearted can democracy be? It points to a very ugly answer: maybe not that big-hearted at all. That in fact America is not exceptional. That it’s just like every other country. That it passes its democracy and it passes all these allegedly big-hearted programs [the New Deal, the G.I. Bill] but still excludes other people,

In a 2010 post about antebellum America, Coates mentioned feminist and abolitionist Angelina Grimke. “Suffice to say that much like Abe Lincoln, and Ulysses Grant, Angelina Grimke was a Walker,” he wrote. “What was the Walker reference?” Rosemartian asked in the comments section. “Just someone who spends their life evolving, or, walking,” Coates replied. “Grant and Lincoln fit in there for me. Malcolm X was another Walker. Walkers tend to be sometimes—even often—wrong. But they are rarely bigots, in the sense of nakedly clinging to ignorance.”

In World War I, France more than any other European power used African troops, including Senegalese riflemen who fought in the victorious battle to take the German colony of Togo. France also sen

Most Africans who participated in that war, however, were recruited or conscripted into labor units, as military service was considered risky — stoking fears that blacks “may get ideas beyond their station,” said World War I historian Albert Grundlingh of the University of Stellenbosch.

But it took close to 70 years for South Africa to pay homage to 700 black laborers who died when their ship, the Mendi, sank in the British Channel in 1917 on its way to France to help in the war effort.

Amid the battles, African cities were taking shape in the first big wave of black urbanization, driven by the demand for labor.

“It was the biggest migration of the early 20th century,” said Mr. Grundlingh, adding that the mass exodus to the cities planted the seeds of segregation, and eventually, black consciousness.

The end of German colonization in Africa saw France take over Togo, while a French-British coalition ruled Cameroon. Belgium got Rwanda and Burundi, leaving Tanzania to the British, and Southwest Africa went to South Africa.

Many of the founding faculty members' "throughout the period of Reconstruction and well into the twentieth century, advocated segregation, the inferiority of African-Americans, and openly embraced the ideology of the Lost Cause of southern slavery,” that recast the South as an idyllic place for both slaves and masters and the Civil War as a battle fought over Southern honor, not slavery

The faculty opposed racial equality after Emancipation and advocated for the maintenance of white political control and against extending suffrage to African Americans, the report said

In the nineteenth and early twentieth centuries, the seminary faculty relied on pseudoscience to justify its white supremacist positions, concluding that "supposed black moral inferiority was connected to biological inferiority,

“It is past time that The Southern Baptist Theological Seminary — the first and oldest institution of the Southern Baptist Convention, must face a reckoning of our own,” Mohler wrote.

a spokesman for Mohler, said the theologian launched the historical investigation because people asked him specific questions “he didn’t know the answer to. We knew there was involvement. We didn’t know the full history.

What does matter, the experts said, are the actions the seminary takes from here and whether it makes reparations.

The school’s leadership needs to sit down with racial and ethnic minorities and “let themselves be led” to racial reconciliation, Tisby said. “They are at the very beginning of the journey,”

Jemar Tisby, a historian who writes about race and Christianity, said he expects many white Evangelicals will push back on the report by saying the seminary is being divisive and re-litigating its past

Critics and other observers said the Southern Baptist Convention for too long has been hesitant to take full ownership of its past, for decades framing its split with northern Baptists as one over theological differences, not slavery

“I think that what he’s trying to do is he’s trying to force the Convention to have a conversation on race and racism that the Convention has really not wanted to have,

while the report is “a step in the right direction,” some sections seem to soften the severity of the seminary’s racist actions. He called the report’s description of faculty’s mixed record on the civil rights movement “double-handed”

In 1995, the Southern Baptist Convention adopted a resolution stating its explicit connection to slavery: “Our relationship to African-Americans has been hindered from the beginning by the role that slavery played in the formation of the Southern Baptist Convention; many of our Southern Baptist forbears defended the right to own slaves, and either participated in, supported, or acquiesced in the particularly inhumane nature of American slavery; and in later years Southern Baptists failed, in many cases, to support, and in some cases opposed, legitimate initiatives to secure the civil rights of African-Americans.”

Mohler wrote in the report. “At that time, I think it is safe to say that most Southern Baptists, having made this painful acknowledgment and lamenting this history, hoped to dwell no longer on the painful aspects of our legacy. That is not possible, nor is it right,” he wrote. “We have been guilty of a sinful absence of historical curiosity. We knew, and we could not fail to know, that slavery and deep racism were in the story."

“[T]he moral burden of history requires a more direct and far more candid acknowledgment of the legacy of this school in the horrifying realities of American slavery, Jim Crow segregation, racism and even the avowal of white racial supremacy,” Mohler wrote in the report. “The fact that these horrors of history are shared with the region, the nation, and with so many prominent institutions does not excuse our failure to expose our own history, our own story, our own cherished heroes, to an honest accounting — to ourselves and to the watching world.”

There have also been notable stumbles. The group voted at its annual meeting in 2017 to condemn the white nationalist movement known as the alt-right — but only after it faced backlash to an earlier decision not to vote on the issue.

Their study, published on Thursday in the journal Cell, concludes that a wave of modern humans departed Africa far earlier than had been known: some 200,000 years ago.

The ancestors of humans and Neanderthals lived about 600,000 years ago in Africa

The scientists also found evidence that people living somewhere in western Eurasia moved back to Africa and interbred with people whose ancestors never left. The new study suggests that all Africans have a substantially greater amount of Neanderthal DNA than earlier estimates.

The research offers a view of human history “almost as a spider web of interactions, rather than a tree with distinct branches.”

These people interbred with Neanderthals, the new study suggests. As a result, Neanderthals were already carrying genes from modern humans when the next big migration from Africa occurred, about 140,000 years later.

The Neanderthal lineage left the continent; the fossils of what we describe as Neanderthals range from 200,000 years to 40,000 years in age, and are found in Europe, the Near East and Siberia.

The human genome is detailed in units called base pairs, about 3 billion such pairs in total. The scientis

ts found that Europeans on average had 51 million base pairs that matched Neanderthal DNA, and East Asians had 55 million.Dr. Akey’s previous research had indicated that East Asians carried far more Neanderthal ancestry than did Europeans.Africans on average had 17 million base pairs that matched Neanderthal DNA — far higher than predicted by the original models describing how humans and Neanderthals interbred.

They concluded that a group of modern humans expanded out of Africa perhaps 200,000 years ago and interbred with Neanderthals. Those modern humans then disappeared. But Neanderthals who lived after that disappearance inherited some modern human DNA.

sitation over the analysis of African DNA, Dr. Reich said the new findings do make a strong case that modern humans departed Africa much earlier than thought

It’s possible that humans and Neanderthals interbred at other times, and not just 200,000 years ago and again 60,000 years ago. But Dr. Akey said that these two migrations accounted for the vast majority of mixed DNA in the genomes of living humans and Neanderthal fossils.

In recent years, Dr. Reich and other researchers have found evidence that ancient people from the Near East moved back into Africa in the past few thousand years and spread their DNA to many African populations.

3.5%, a 50-year-low, the black unemployment rate was 5.8%. The white unemployment rate was 3.1%.

“Whatever is being projected for the national unemployment rate, in most instances, we expect to see something close to twice that for black Americans.”

For Yolanda Murray of Detroit, Michigan, not having savings meant weeks of panic trying to figure out how she was going to pay the bills that came on 1 April after she was furloughed from her job at a hotel.

last hired, first fired” phenomenon dramatically affects black Americans more than any other group in the US due to the country’s history of racism and segregation of black Americans in the work sector.

Working in these fields leads to lower wages – black Americans have the lowest median wage of any racial group in the US – and the jobs are often seen as the most expendable during an economic downturn.

Even with a low unemployment rate, wage growth for low-wage workers, especially for black workers, has been slow. Black Americans have seen the slowest wage growth compared with other groups of Americans, reaching a growth rate that was four times slower at certain wage distribution levels, according to a 2018 Economic Policy Institute report.

The reason why African Americans bear the brunt of downturns more is that when firing decisions start to occur the least educated and those with the least experience tend to be let go first. There is also continued discrimination in the workplace,” Rodgers said.

t’s like how am I going to maintain all of this?” Murray said. Weeks after she filed her application for unemployment insurance, payments started coming in and Murray was able to pay her bills again.

Murray and her unionized co-workers spent 28 days striking for higher wages and better healthcare. At the time, workers at the hotel had not had wage rises since before the last recession, and healthcare costs were so expensive that Murray could only afford to cover herself, leaving her two children out of her plan.

Trump’s repeated claims that he has been the best president for African Americans was repeatedly pegged to falling unemployment numbers. But those numbers only tell a partial story, as work by Rodgers and others has shown. Black families are especially vulnerable to economic downturns because they lack the savings that can act as a buffer against unexpected layoffs or lost wages. And during the last recovery they lost ground against their white peers.

compared with 9%, respectively. And the black homeownership rate is the lowest of any racial group in the US and has consistently been about 30% lower than the white homeownership rate over the years, even as the economy was getting stronger.

“Wealth allows you to respond to that unexpected health emergency, that broken hole in the tire you have to replace. It also allows you to buy a home, put your kids through school,” said Danyelle Solomon, vice-president of the race and ethnicity program at the Center for American Progress.

Experts agree that being poor has costly effects on a person’s health: for adults living in extreme poverty, being poor can cost up to 15 years of life expectancy.

ave seen higher death rates due to Covid-19 compared with any other group in the US. Black Americans made up 25% of deaths from Covid-19 in the US though they make up a little under 13% of the US population.

“National emergencies, pandemics, epidemics, what they do is they spotlight inequality,” Solomon said. “What we see in Covid-19 is no different. It’s highlighting racial disparities at every single level that have been with our society for a very long time.”

on sensitive topics, every survey method will elicit substantial misreporting. People have no incentive to tell surveys the truth.

How, therefore, can we learn what our fellow humans are really thinking and doing? Big data

Think of Google searches. Remember the conditions that make people more honest. Online? Check. Alone? Check. No person administering a survey? Check.

I am now convinced that Google searches are the most important dataset ever collected on the human psyche.

How many American men are gay? This is a regular question in sexuality research. Yet it has been among the toughest questions for social scientists to answer. Psychologists no longer believe Alfred Kinsey’s famous estimate – based on surveys that oversampled prisoners and prostitutes – that 10% of American men are gay. Representative surveys now tell us about 2% to 3% are

About 2.5% of male Facebook users who list a gender of interest say they are interested in men; that corresponds roughly with what the surveys indicate.

There is clearly some mobility – from Oklahoma City to San Francisco, for example. But I estimate that men moving to someplace more open-minded can explain less than half of the difference in the openly gay population in tolerant versus intolerant states.

If mobility cannot fully explain why some states have so many more openly gay men, the closet must be playing a big role. Which brings us back to Google

about 5% of male porn searches are for gay-male porn. Overall, there are more gay porn searches in tolerant states compared with intolerant states.

one consequence of my estimate is clear: an awful lot of men in the United States, particularly in intolerant states, are still in the closet. They don’t reveal their sexual preferences on Facebook. They don’t admit it on surveys. And, in many cases, they may even be married to women.

It turns out that wives suspect their husbands of being gay rather frequently. They demonstrate that suspicion in the surprisingly common search: “Is my husband gay?” The word “gay” is 10% more likely to complete searches that begin “Is my husband...” than the second-place word, “cheating”. It is eight times more common than “an alcoholic” and 10 times more common than “depressed”.

On Google, there are 16 times more complaints about a spouse not wanting sex than about a married partner not being willing to talk. There are five-and-a-half times more complaints about an unmarried partner not wanting sex than an unmarried partner refusing to text back.

Google data also suggests a reason people may be avoiding sex so frequently: enormous anxiety, with much of it misplaced. Start with men’s anxieties. It isn’t news that men worry about how well endowed they are, but the degree of this worry is rather profound. Men Google more questions about their sexual organ than any other body par

Men conduct more searches for how to make their penises bigger than how to tune a guitar, make an omelette, or change a tyre. Men’s top Googled concern about steroids isn’t whether they may damage their health but whether taking them might diminish the size of their penis. Men’s top Googled question related to how their body or mind would change as they aged was whether their penis would get smaller.

Do women care about penis size? Rarely, according to Google searches. For every search women make about a partner’s phallus, men make roughly 170 searches about their own

Men’s second most common sex question is how to make their sexual encounters longer. Once again, the insecurities of men do not appear to match the concerns of women. There are roughly the same number of searches asking how to make a boyfriend climax more quickly as climax more slowly.

while it’s true that overall interest in personal appearance skews female, it’s not as lopsided as stereotypes would suggest. According to my analysis of Google AdWords, which measures the websites people visit, interest in beauty and fitness is 42% male, weight loss is 33% male, and cosmetic surgery is 39% male

you could call it progress that many people today feel they will be judged if they admit they judge other people based on their ethnicity, sexual orientation, or religion. But many Americans still do. You can see this on Google

African Americans are the only group that faces a “rude” stereotype

Nearly every group is a victim of a “stupid” stereotype; the only two that are not: Jews and Muslims.

The “evil” stereotype is applied to Jews, Muslims, and gay people but not black people, Mexicans, Asians, and Christians.

Muslims are the only group stereotyped as terrorists.

minutes after the media first reported one of the shooters’ Muslim-sounding names, a disturbing number of Californians decided what they wanted to do with Muslims: kill them. The top Google search in California with the word “Muslims” in it at the time was “kill Muslims”

In the days following the San Bernardino attack, for every American concerned with “Islamophobia”, another was searching for “kill Muslims”. While hate searches were approximately 20% of all searches about Muslims before the attack, more than half of all search volume about Muslims became hateful in the hours that followed it. And this minute-by-minute search data can tell us how difficult it can be to calm this rage.

Obama’s speech, in other words, was judged a major success. But was it?

In his speech, the president said: “It is the responsibility of all Americans – of every faith – to reject discrimination.” But searches calling Muslims “terrorists”, “bad”, “violent”, and “evil” doubled during and shortly after the speech.

Obama also said: “It is our responsibility to reject religious tests on who we admit into this country.” But negative searches about Syrian refugees, a mostly Muslim group then desperately looking for a safe haven, rose 60%, while searches asking how to help Syrian refugees dropped 35%

Obama asked Americans to “not forget that freedom is more powerful than fear”. Yet searches for “kill Muslims” tripled during his speech. In fact, just about every negative search we could think to test regarding Muslims shot up during and after Obama’s speech, and just about every positive search we could think to test declined.

new data from the internet, offering digital truth serum, suggested that the speech actually backfired in its main goal. Instead of calming the angry mob, as everybody thought he was doing, the internet data tells us that Obama actually inflamed it.

Searches for “nigger jokes” are 17 times more common than searches for “kike jokes”, “gook jokes”, “spic jokes”, “chink jokes”, and “fag jokes” combined. When are these searches most common? Whenever African Americans are in the news.

Any theory of racism has to explain a big puzzle in America. On the one hand, the overwhelming majority of black Americans think they suffer from prejudice – and they have ample evidence of discrimination in police stops, job interviews, and jury decisions. On the other hand, very few white Americans will admit to being racist. The dominant explanation among political scientists recently has been that this is due, in large part, to widespread implicit prejudice. White Americans may mean well, this theory goes, but they have a subconscious bias, which influences their treatment of black Americans.

There is, though, an alternative explanation for the discrimination that African Americans feel and whites deny: hidden explicit racism. Suppose there is a reasonably widespread conscious racism of which people are very much aware but to which they won’t confess – certainly not in a survey

That’s what the search data seems to be saying.

this gender bias is not grounded in reality. About 28% of girls are overweight, while 35% of boys are. Even though scales measure more overweight boys than girls, parents see – or worry about – overweight girls much more frequently than overweight boys. Parents are also one-and-a-half times more likely to ask whether their daughter is beautiful than whether their son is handsome.

And then there is the phenomenon of Donald Trump’s candidacy. When Nate Silver, the polling guru, looked for the geographic variable that correlated most strongly with support in the 2016 Republican primary for Trump, he found it in the map of racism I had developed.

The primary explanation for discrimination against African Americans today is not the fact that the people who agree to participate in lab experiments make subconscious associations between negative words and black people; it is the fact that millions of white Americans continue to do things like search for “nigger jokes”

, I was able to use Google searches to find evidence of implicit prejudice against another segment of the population: young girls. And who, might you ask, would be harbouring bias against girls? Their parents.

Prior to the Google data, we didn’t have a convincing measure of this virulent animus. Now we do. We are, therefore, in a position to see what it explains. It explains why Obama’s vote totals in 2008 and 2012 were depressed in many regions. It also correlates with the black-white wage gap, as a team of economists recently reported. The areas that I had found make the most racist searches underpay black people.

Perhaps young boys are more likely than young girls to use big words or show objective signs of giftedness? Nope. If anything, it’s the opposite. At young ages, girls have consistently been shown to have larger vocabularies and use more complex sentences. In American schools, girls are 9% more likely than boys to be in gifted programmes. Despite all this, parents looking around the dinner table appear to see more gifted boys than girls.

What then are parents’ overriding concerns regarding their daughters? Primarily, anything related to appearance.

Parents are about twice as likely to ask how to get their daughters to lose weight as they are to ask how to get their sons to do the same

Parents are two-and-a-half times more likely to ask “Is my son gifted?” than “Is my daughter gifted?”

I did not find a significant relationship between any of these biases and the political or cultural makeup of a state. It would seem this bias against girls is more widespread and deeply ingrained than we’d care to believe.

Let’s return to Obama’s speech about Islamophobia. Recall that every time he argued that people should respect Muslims more, the people he was trying to reach became more enraged. Google searches, however, reveal that there was one line that did trigger the type of response Obama might have wanted. He said: “Muslim Americans are our friends and our neighbours, our co-workers, our sports heroes and, yes, they are our men and women in uniform, who are willing to die in defence of our country.”

When we lecture angry people, the search data implies that their fury can grow. But subtly provoking people’s curiosity, giving new information, and offering new images of the group that is stoking their rage may turn their thoughts in different, more positive directions.

What’s your background?I’d describe myself as a data scientist, but my PhD is in economics. When I was doing my PhD, in 2012, I found this tool called Google Trends that tells you what people are searching, and where, and I became obsessed with it.

What would your search records reveal about you?They could definitely tell I’m a hypochondriac because I’m waking up in the middle of the night doing Google searches about my health. There are definitely things about me that you could figure out. When making claims about a topic, it’s better to do it on aggregate, but I think you can figure out a lot, if not everything, about an individual by what they’re searching on Google.

All this data I’m talking about is public

Does it change your view of human nature? Are we darker and stranger creatures than you realised?Yeah. I think I had a dark view of human nature to begin with, and I think now it’s gotten even darker. I think the degree to which people are self-absorbed is pretty shocking

When Trump became president, all my friends said how anxious they were, they couldn’t sleep because they’re so concerned about immigrants and the Muslim ban. But from the data you can see that in liberal parts of the country there wasn’t a rise in anxiety when Trump was elected. When people were waking up at 3am in a cold sweat, their searches were about their job, their health, their relationship – they’re not concerned about the Muslim ban or global warming.

Was the Google search data telling you that Trump was going to win?I did see that Trump was going to win. You saw clearly that African American turnout was going to be way down, because in cities with 95% black people there was a collapse in searches for voting information. That was a big reason Hillary Clinton did so much worse than the polls suggested.

some South African scientists have pointed out that the travel ban may also be hampering the race to learn more about Omicron by blocking supplies of the reagents they need to study it.

Partly because of this South Africa was, until recently, recording less than one-tenth as many daily covid cases as Britain. “It boggles the mind that people in the United Kingdom can pile into a full football stadium and in the United States it appears as though it’s business as usual, but as soon as something happens on African soil, those countries go into a hysterical tailspin,”

The new travel restrictions will wallop the region’s tourism industry, just as hotels, game reserves and wine estates were preparing for their busiest months of the year

Because of the drop in tourism and the imposition of lockdowns the economy shrank by about 6% last year. Thousands of small businesses collapsed

The ripples may spread far beyond southern Africa to countries such as Kenya and Uganda that do not yet face travel restrictions.

South Africa’s health workers are gearing up for another December of mayhem as covid’s fourth wave washes over the country.

The emergence of Omicron, which seems to spread easily, will probably upset those estimates. “It looks like it's spreading quickly but there’s so much that’s unknown, specifically if it will evade the vaccines and its severity,”

“The entire world is suffering from this conflict, but we in Africa are already facing the collateral damages,” said Ousmane Sène

The Kremlin said in a statement that the two leaders would discuss “the expansion of political dialogue and economic and humanitarian cooperation with the countries of the continent.”

More than 14 million people are on the brink of starvation in the Horn of Africa, according to relief groups, and nearly 40 million people are at imminent risk of famine in West Africa this year, according to the World Food Program, a United Nations agency.

For months, African leaders also shunned President Volodymyr Zelensky of Ukraine, who asked at least twice to address the African Union. Mr. Sall said Thursday that Mr. Zelensky could soon address the organization in a videoconference, although no date has been announced.

In West Africa, one of the most visible effects of the war so far has been on bread prices that were already on the rise. In Burkina Faso, bakers went on strike last month after the government shuttered bakeries that had raised the price of a baguette. In the Ivory Coast, bakers have decreased the size of the baguette in the face of soaring wheat costs.

“By disrespecting @repjohnlewis, @realDonaldTrump dishonored Lewis’ sacrifice & demeaned Americans & the rights, he nearly died 4. Apologize,” he wrote.

Many of the members of Congress who will not attend Mr. Trump’s inauguration said they planned to instead meet with activists and focus on how to push back against Mr. Trump’s administration.

The deep unease that many African-Americans feel about Mr. Trump has also set off a backlash toward black celebrities who appear with him

Bush also destroyed centrist Democrats intellectually, by making it impossible for them to credibly critique liberalism from the right.

. In the late ’80s and the ’90s, centrist Democrats had also argued that Reagan’s decision to boost defense spending and aid the Afghan mujahideen had helped topple the Soviet empire. But in 2003, when Bush invaded Iraq, he sparked the greatest foreign-policy catastrophe since Vietnam.

If the lesson of the Reagan era had been that Democrats should give a Republican president his due, the lesson of the Bush era was that doing so brought disaster.

In the Senate, Bush’s 2001 tax cut passed with 12 Democratic votes; the Iraq War was authorized with 29. As the calamitous consequences of these votes became clear, the revolt against them destroyed the Democratic Party’s centrist wing

With the Dean campaign came an intellectual revolution inside the Democratic Party. His insurgency helped propel Daily Kos, a group blog dedicated to stiffening the liberal spine. It energized the progressive activist group MoveOn. It also coincided with Paul Krugman’s emergence as America’s most influential liberal columnist and Jon Stewart’s emergence as America’s most influential liberal television personality.

All of this has shaped the Clinton campaign’s response to Sanders. At the first Democratic debate, she noted that, unlike him, she favors “rein[ing] in the excesses of capitalism” rather than abandoning it altogether. But the only specific policy difference she highlighted was gun control, on which she attacked him from the left.

Whereas the party’s most respected thinkers had once urged Democrats to critique liberal orthodoxy, they now criticized Democrats for not defending that orthodoxy fiercely enough. The presidency of George W. Bush had made Democrats unapologetically liberal, and the presidency of Barack Obama was the most tangible result.

that’s only half the story. Because if George W. Bush’s failures pushed the Democratic Party to the left, Barack Obama’s have pushed it even further. If Bush was responsible for the liberal infrastructure that helped elect Obama, Obama has now inadvertently contributed to the creation of two movements—Occupy and Black Lives Matter—dedicated to the proposition that even the liberalism he espouses is not left-wing enough.

Todd Gitlin quotes Jeremy Varon, a close observer of Occupy who teaches at the New School for Social Research, as saying, “This is the Obama generation declaring their independence from his administration. We thought his voice was ours. Now we know we have to speak for ourselves.

Occupy. The movement may have burned out, but it injected economic inequality into the American political debate

The same anger that sparked Occupy—directed not merely at Wall Street but at the Democratic Party elites who coddled it—fueled Bill de Blasio’s election and Elizabeth Warren’s rise to national prominence. And without Occupy, it’s impossible to understand why a curmudgeonly Democratic Socialist from Vermont is seriously challenging Hillary Clinton

the Democracy Alliance, the party’s most influential donor club, which includes mega-funders such as George Soros and Tom Steyer, has itself shifted leftward during the Obama years. In 2014, it gave Warren a rapturous welcome when she spoke at the group’s annual winter meeting. Last spring it announced that it was making economic inequality its top priority.

By the time Barack Obama defeated Hillary Clinton for the Democratic presidential nomination in 2008, in part because of her support for the Iraq War, the mood inside the party had fundamentally changed.

Moreover, the Occupy-Warren-Sanders axis has influenced Clinton’s own economic agenda, which is significantly further left than the one she ran on in 2008. She has called for tougher regulation of the financial industry, mused about raising Social Security taxes on the wealthy (something she opposed in 2008), and criticized the Trans-Pacific Partnership (a trade agreement she once gushed about).

“Black Lives Matter developed in the wake of the failure of the Obama administration,” argues the Cornell sociologist Travis Gosa, a co-editor of The Hip Hop & Obama Reader. “Black Lives Matter is the voice of a Millennial generation that’s been sold a ba

Had Black Lives Matter existed when Bill Clinton was seeking the presidency, he probably would have run against the group

Today, by contrast, the Democratic Establishment has responded to Black Lives Matter much as it responded to Occupy: with applause

what’s most remarkable isn’t Hillary Clinton’s move to the left, or the Democratic Party’s. It’s the American public’s willingness to go along.

Much of this shift is being driven by a changing mood among whites. Between January and April alone, according to a YouGov poll, the percentage of whites who called deaths like those of Michael Brown and Freddie Gray “isolated incident[s]” dropped 20 points. There’s even been movement within the GOP. From 2014 to 2015, the percentage of Republicans saying America needs to make changes to give blacks an equal chance rose 15 points—more than the percentage increase among Democrats or Independents.

Most interesting—because he is the Republican candidate with the keenest sense of how to appeal to the general electorate—has been the approach of Senator Marco Rubio. In August, a Fox News anchor asked him about Black Lives Matter. Instead of condemning the movement, Rubio told the story of an African American friend of his whom police had stopped eight or nine times over the previous 18 months even though he had never broken the law. “This is a problem our nation has to confront,” Rubio declared. Then he talked about young African Americans who get arrested for nonviolent offenses and pushed into plea deals by overworked public defenders. The government, he said, must “look for ways to divert people” from going to jail “so that you don’t get people stigmatized early in life.”

Conservative Republicans didn’t talk this way in the ’90s. They didn’t talk this way even in the early Obama years. The fact that Rubio does so now is more evidence that today, unlike in the mid-’60s, the debate about race and justice isn’t moving to the right. It’s moving further left

What’s different this time? One difference is that in the 1960s and ’70s, crime exploded, fueling a politics of fear and vengeance. Over the past two decades, by contrast, crime has plummeted. And despite some hyperbolic headlines, there’s no clear evidence that it’s rising significantly again.

When the Williams Institute at the UCLA School of Law examined polls, it found that between two-thirds and three-quarters of Americans now support barring discrimination against transgender people.

Most Americans, in other words, having decided that discriminating against lesbians and gay men was wrong, have simply extended that view to transgender people via what Flores describes as a “mechanism of attitude generalization.”

In polling, Americans typically say they favor smaller government in general while supporting many specific government programs. When Bill Clinton took office in 1993, Americans said they favored “a smaller government providing fewer services” over “a bigger government providing more services” by 37 percentage points. When Obama took power in 2009, the margin was a mere eight points. And despite the president’s many economic interventions, the most recent time Pew asked that question, in September 2014, the margin was exactly the same.

This intervention has sparked an angry response on the Republican right, but not among Americans as a whole.

On health care, the story is similar: no public backlash. When Obama signed the Affordable Care Act in March 2010, most polls showed Americans opposing it by about eight to 10 points. Today, the margin is almost identical

Little has changed on taxes, either, even though Obama allowed some of the tax cuts passed under George W. Bush to expire. The percentage of Americans who say they pay more than their fair share in taxes is about the same as it was in the spring of 2010 (

in an era when government has grown more intrusive, African American activists have grown more confrontational, and long-standing assumptions about sexual orientation and gender identity have been toppled, most Americans are not yelling “stop,” as they began doing in the mid-1960s. The biggest reason: We’re not dealing with the same group of Americans.

On issue after issue, it is the young who are most pleased with the liberal policy shifts of the Obama era, and most eager for more

It is largely because of them that the percentage of Americans who want government to “promote traditional values” is now lower than at any other time since Gallup began asking the question in 1993, and that the percentage calling themselves “socially liberal” now equals the percentage calling themselves “socially conservative” for the first time since Gallup began asking that question in 1999.

Millennials are also sustaining support for bigger government. The young may not have a high opinion of the institutions that represent them, but they nonetheless want those institutions to do more

They were also 25 points more likely than those 65 and older to approve of Occupy Wall Street and 36 points more favorable toward socialism, which they actually preferred to capitalism, 49 percent to 46 percent. As the Pew report put it, “Millennials, at least so far, hold ‘baked in’ support for a more activist government.

The press often depicts American politics as a battle pitting ever more liberal Democrats against ever more conservative Republicans. Among the young, however, that’s inaccurate. Young Democrats may be more liberal than their elders, but so are young Republicans. According to Pew, a clear majority of young Republicans say immigrants strengthen America, half say corporate profits are too high, and almost half say stricter environmental laws are worth the cost—answers that sharply distinguish them from older members of the GOP.

Asked how they categorize themselves ideologically, more than two-thirds of Republican Millennials call themselves either “liberal” or “mixed,” while fewer than one-third call themselves “conservative.” Among the oldest Republicans, that breakdown is almost exactly reversed.

Millennials are not liberal primarily because they are young. They are liberal because their formative political experiences were the Iraq War and the Great Recession, and because they make up the most secular, most racially diverse, least nationalistic generation in American history. And none of that is likely to change.

America is not governed by public-opinion polls, after all. Congressional redistricting, felon disenfranchisement, and the obliteration of campaign-finance laws all help insulate politicians from the views of ordinary people, and generally empower the right. But despite these structural disadvantages, Obama has enacted a more consequential progressive agenda than either of his two Democratic predecessors did

If Clinton does win, it’s likely that on domestic policy, she will govern to Obama’s left. (On foreign policy, where there is no powerful left-wing activist movement like Occupy or Black Lives Matter, the political dynamics are very different.) Clinton’s campaign proposals already signal a leftward shift. And people close to her campaign suggest that among her top agenda items would be paid family leave, debt-free college tuition, and universal preschool

Clinton will face this reality from her first day in office. And she will face it knowing that because she cannot inspire liberals rhetorically as Obama can, they will be less likely to forgive her heresies on policy. Like Lyndon B. Johnson after John F. Kennedy, she will have to deliver in substance what she cannot deliver in style.

it’s likely that any Republican capable of winning the presidency in 2016 would govern to the left of George W. Bush. In the first place, winning at all would require a different coalition. When Bush won the presidency in 2000, very few Millennials could vote. In 2016, by contrast, they will constitute roughly one-third of those who turn out

In 2000, African Americans, Hispanics, and Asians constituted 20 percent of voters. In 2016, they will constitute more than 30 percent.

even if the 2016 Republican nominee wins 60 percent of the white vote (more than any GOP nominee in the past four decades except Reagan, in 1984, has won), he or she will still need almost 30 percent of the minority vote. Mitt Romney got 17 percent.

This need to win the votes of Millennials and minorities, who lean left not just on cultural issues but on economic ones, will shape how any conceivable Republican president campaigns in the general election, and governs once in office.

If America’s demographics have changed since the Bush presidency, so has the climate among conservative intellectuals. There is now an influential community of “reformocons”—in some ways comparable to the New Democratic thinkers of the 1980s—who believe Republicans have focused too much on cutting taxes for the wealthy and not enough on addressing the economic anxieties of the middle and working classes.

The candidate closest to the reformocons is Rubio, who cites several of them by name in his recent book. He says that partially privatizing Social Security, which Bush ran on in 2000 and 2004, is an idea whose “time has passed.” And unlike Bush, and both subsequent Republican presidential nominees, Rubio is not proposing a major cut in the top income-tax rate. Instead, the centerpiece of his economic plan is an expanded child tax credit, which would be available even to Americans who are so poor that they don’t pay income taxes

it’s likely that were he elected, Rubio wouldn’t push through as large, or as regressive, a tax cut as Bush did in 2001 and 2003. Partly, that’s because a younger and more ethnically diverse electorate is less tolerant of such policies. Partly, it’s because Rubio’s administration would likely contain a reformocon faction more interested in cutting taxes for the middle class than for the rich. And partly, it’s because the legacy of the Bush tax cuts themselves would make them harder to replicate

A key figure in passing the Bush tax cuts was Federal Reserve Chairman Alan Greenspan, who in 2001 warned that unless Washington lowered tax rates, surpluses might grow too large, thus producing a dangerous “accumulation of private assets by the federal government.” Greenspan’s argument gave the Bush administration crucial intellectual cover. But the idea now looks laughable. And it’s hard to imagine the current Federal Reserve chair, Janet Yellen, endorsing large upper-income tax cuts in 2017.

the kind of centrist, Chamber of Commerce–friendly Democrats who helped Bush pass his tax plan in 2001—including Max Baucus, John Breaux, Mary Landrieu, Zell Miller, Max Cleland, Tim Johnson, Blanche Lambert Lincoln—barely exist anymore. The Democrats’ shift left over the past decade and a half means that a President Rubio would encounter more militant opposition than Bush did in 2001

the next Republican president won’t be able to return the nation to the pre-Obama era.

That’s what happened when Dwight Eisenhower followed Franklin D. Roosevelt and Harry Truman. Ike moderated the growth in government expansion that had begun in the 1930s, but he didn’t return American politics to the 1920s, when the GOP opposed any federal welfare state at all. He in essence ratified the New Deal

It’s also what happened when Bill Clinton followed Ronald Reagan and George H. W. Bush. By passing punitive anticrime laws, repealing restrictions on banks, signing NAFTA, cutting government spending to balance the budget, reforming welfare, and declaring that the “era of big government is over,” Clinton acknowledged that even a Democratic president could not revive the full-throated liberalism of the 1960s and ’70s. He ratified Reaganism.

Barack Obama sought the presidency hoping to be the Democrats’ Reagan: a president who changed America’s ideological trajectory. And he has changed it. He has pushed the political agenda as dramatically to the left as Reagan pushed it to the right, and, as under Reagan, the public has acquiesced more than it has rebelled.

This meant that Kaunatjike's homeland was controlled by descendants of Dutch and British colonists—white rulers who, in 1948, made apartheid the law of the land. Its shadow stretched from the Indian Ocean to the Atlantic, covering an area larger than Britain, France, and Germany combined.

“Our fight was against the regime of South Africa,” says Kaunatjike, now a 68-year-old resident of Berlin. “We were labeled terrorists.”

During the 1960s, hundreds of anti-apartheid protesters were killed, and thousands more were thrown in jail. As the South African government tightened its fist, many activists decided to flee. “I left Namibia illegally in 1964,” says Kaunatjike. “I couldn't go back.”

Germans first reached the arid shores of southwestern Africa in the mid-1800s. Travelers had been stopping along the coast for centuries, but this was the start of an unprecedented wave of European intervention in Africa. Today we know it as the Scramble for Africa.

The German flag soon became a beacon for thousands of colonists in southern Africa—and a symbol of fear for local tribes, who had lived there for millennia. Missionaries were followed by merchants, who were followed by soldiers.

Indigenous people didn't accept all this willingly. Some German merchants did trade peacefully with locals. But like Belgians in the Congo and the British in Australia, the official German policy was to seize territory that Europeans considered empty, when it most definitely was not.

During apartheid, he explains, blacks were forcibly displaced to poorer neighborhoods, and friendships with whites were impossible. Apartheid translates to “apartness” in Afrikaans. But many African women worked in German households. “Germans of course had relationships in secret with African women,” says Kaunatjike. “Some were raped.” He isn't sure what happened to his own grandmothers.

the post-Obama black electorate will probably be characterized by three things: stratified voter participation, increased reliance on alternative methods of political pressure, and initial signs of growing partisan and political diversity.

Though overall black voter participation increased between 2008 and 2012, Obama’s reelection came courtesy of African Americans over 45 years old. But for blacks born in the late 1980s onward, their turnout dropped nearly 7 percent in that same period, marking the first time that has occurred in decades

The post-Obama bloc employs a different strategy to bring about change—one rooted in creativity and energy. It is because of them that Black Lives Matter exists. Their hunger strike and protest at the University of Missouri, emblematic of campus protests across the country, accomplished what complaints to the state legislature and the board of directors could not. In South Carolina, one of them yanked the state’s Confederate battle flag off the pole before the governor officially took it down. Another wrote a reparations article that created a national conversation

Half of the newest black members of Congress are Republicans, and more black Republicans have run for the presidency since 2000 than black Democrats.

In 2012, GOP presidential candidate Mitt Romney nearly doubled the percentage of black Republican votes compared with McCain in 2008

So what does all this mean for 2016? It won’t take long to find out. The first substantial glimpse of the post-Obama black electorate will occur when South Carolina’s African American voters head to the polls for the state’s open-primary elections this month.

One of these groups can be traced as far back as 35,000 years, thanks to a skeleton discovered at a site in Belgium called Goyet. The Goyet-related people spread across Europe, only to be replaced on much of the continent near the end of the Ice Age by a genetically distinct population. The earliest sign of the second group appears 14,000 years ago, known to researchers by DNA in a skeleton at an Italian site called Villabruna.

the Goyet and Villabruna people coexisted. Hunter-gatherers across the peninsula had a mixture of ancestry from the two peoples.

But whatever solitude Iberia might have offered came to an end about 7,500 years ago, when new people arrived with crops and livestock. These first farmers, originally from Anatolia, brought with them a distinctive genetic signature.

Ninety percent of the DNA from the later skeletons derives from the Anatolian farmers; 10 percent comes from the hunter-gatherers.

Starting about 6,000 years ago, Dr. Olalde and his colleagues found, hunter-gatherer ancestry in Iberian farmers actually increased to 20 percent.

A skeleton from an elaborate grave in central Spain about 4,400 years old belonged to a man whose ancestry was 100 percent North African

findings suggest that people were moving into Iberia from Africa more than 3,000 years before the rise of the Roman Empire. “These are cosmopolitan places,”

About 4,500 years ago, still another wave of people arrived, profoundly altering the makeup of Iberia.A few centuries earlier, nomads from the steppes of what is now Russia turned up in Eastern Europe with horses and wagons. They spread across the continent, giving up nomadic life and intermarrying with European farmers.

When they finally reached Iberia, these people spread out far and wide. “They really have an impact on the whole peninsula,”

DNA from the men, however, all traced back to the steppes. The Y chromosomes from the male farmers disappeared from the gene pool.

To archaeologists, the shift is a puzzle.“I cannot say what it is,

he ruled out wars or massacres as the cause. “It’s not a particularly violent time,”

Iberian farmers originally lived in egalitarian societies, storing their wealth together and burying their dead in group graves.

over several centuries, palaces and fortresses began to rise, and power became concentrated in the hands of a few. Dr. Risch speculated that the cultural shift had something to do with the genetic shift

The Bronze Age in Iberia was followed by the Iron Age about 2,800

Iron Age Iberians could trace some of their ancestry to new waves of people arriving from northern and Central Europe, possibly marking the rise of so-called Celtiberian culture on the peninsula.

scientists found a growing amount of North African ancestry in skeletons from the Iron Age. That may reflect trade around the Mediterranean, which brought North Africans to Iberian towns, where they settled down.

North African ancestry increased in Iberia even more after Romans took control. Now the peninsula was part of an empire that thrived on widespread trade. At the same time, people from southern Europe and the Near East also began leaving an imprint

The Basque speak a language that is unrelated to other European tongues. Some researchers have speculated that they descended from a population that had been distinct since the Bronze Age or earlier.Genetically, at least, that doesn’t seem to be the case. Before the Roman era, the Basque had DNA that was indistinguishable from that of other Iron Age Iberians

After the fall of Rome, ancient DNA in Iberia reflects its medieval history. Skeletons from the Muslim era show growing ancestry from both North Africa and sub-Saharan Africa.

The researchers were also able to group Spaniards into five genetic clusters. On a map, these groups form five strips running north to south. Those strips line up neatly with history.

Working along an east-west transect through central England and Wales, the scientists discovered that the mix of Y-chromosomes characteristic of men in the English towns was very different from that of men in the Welsh towns: Wales was the primary Celtic holdout in Western Britannia during the ascendance of the Anglo-Saxons. Using computer analysis, the researchers explored how such a pattern could have arisen and concluded that a massive replacement of the native fourth-century male Britons had taken place. Between 50 percent and 100 percent of indigenous English men today, the researchers estimate, are descended from Anglo-Saxons who arrived on England’s eastern coast 16 centuries ago.

So what happened? Mass killing, or “population replacement,” is one possible explanation. Mass migration of Anglo-Saxons, so that they swamped the native gene pool, is another.

Yet no archaeological or historical evidence from the fifth and sixth centuries hints at the immense scale of violence or migration that would be necessary to explain this genetic legacy. The science hinted at an untold story.

across entire fields of inquiry, the traditional boundaries between history and prehistory have been melting away as the study of the human past based on the written record increasingly incorporates the material record of the natural and physical sciences.

The study of the human past, in other words, has entered a new phase in which science has begun to tell stories that were once the sole domain of humanists.

Thomas had found that genetically, not one of the English towns he sampled was significantly different from the others. Welsh towns, on the other hand, were significantly different from each other and from the English towns.

Most importantly, he found that inhabitants of  the Dutch province of Friesland were indistinguishable genetically from the English town-dwellers. Friesland is one of the known embarkation points of the Angl0-Saxons--and the language spoken there is the closest living relative to English.

The implications are profound: “Suddenly, we have all these genuine historical observations that need to be taken on board by historians and archaeologists and they raise a whole series of new questions, focusing particularly on…what is going on at the intimate level of this new civilization that is being born in the ruins of the Roman empire. The history of Europe will never be the same.”

But most archaeologists and historians who understand the economic capacity of the era, he noted, “find such massive contributions to the English gene pool to be completely unacceptable.

“But still, the genetic data are quite robust,” Thomas pointed out. “This is where the idea of an apartheid-like social structure comes in.” He has advanced a theory that a sexually biased, ethnically driven reproductive pattern, in which Anglo-Saxon males fathered children with Anglo-Saxon females and possibly Celtic females, while the reproductive activities of Romano-Celtic males were more restricted, is the most plausible explanation for the demographic, archaeological, and genetic patterns seen today. 

In an attempt to explain the remarkable similarity between Frisian and English towns, Thomas and colleagues constructed a population simulation model on a computer. He tested many theories: common ancestry dating back to the Neolithic age; background migration over centuries and even millennia; and a mass-migration event that, he calculated, would have had to involve at least 50 percent replacement--the movement, in other words, of a million people.

Simulating such an advantage, and choosing an arbitrary figure of 10 percent migration, Thomas found that the Y chromosomes of native Britons could have been replaced in the general population in as few as five generations. 

by the 1970s, he continues, scholars began to realize there never was a homogenous “nation” of Germans in northern Europe, just small tribes that coalesced along the Roman frontier in what were political and cultural, rather than biological, federations, as their very names suggest: Alemanni, meaning “all men”; Goths, meaning “good guys.”

The Romans, scholars believed, provided a common enemy, and that unified the disparate Germanic tribes. This line of reasoning led historians to a further thought: maybe the Anglo-Saxon identity was similarly socially constructed, and not biological after all

More recent historical scholarship, therefore, has increasingly emphasized discovering the extent to which the barbarian migrations were really a process of ethnogenesis--the creation of new ethnic identities, as the merchant’s story illustrates.

“There is lots of evidence for it,” McCormick says. “But now you have Mark Thomas telling us that you could actually study mating patterns. That is utterly unanticipated.” The work raises a host of new questions: What was women’s role in the barbarian settlements? Were Anglo-Saxon men mating with Celtic women? Or were there women in those invading boats, and if so, how many? What happened to the Romano-Celtic men? Were they killed? 

There is some support for this in ancient English laws, which indicate that Britons and Anglo-Saxons were legally and economically different even in the seventh century, long after the initial migration. Thomas cited wergild (blood money) payments as one example: “Killing an Anglo-Saxon was a costly business, but killing a native Briton was quite cheap.” This points to differences in economic status. And differences in wealth “almost always result in differences in reproductive output,” he said. “Sometimes two- and three-fold differences.” To the extent Anglo-Saxons were able to have and support more children, this could lead to a gradual replacement of the indigenous Y-chromosome over many generations

The Y-chromosome can be a particularly revealing signature of the past when compared to other kinds of genetic data. Among African Americans in the United States, for example, Y-chromosomes are about 33 percent European, he says, though the proportion varies from city to city. But those same African Americans’ mitochondrial DNA, which comes from the female line, is only about 6 percent European. And that, says Reich, “tells you about the history of this country, in which men contributed about three-fourths of the European ancestry that is present in the African-American population data. The data speak to a history in which white male slaveowners exploited women of African descent--a fact that is well documented in the historical record. That there is evidence of this in genetic data should be no surprise.”

Most Americans associate Medellín with the drug cartels of that isolated region. But the remoteness has also preserved a genetic legacy that can be traced to the conquistadores. As described in a paper by Andrés Ruiz-Linares of University College London, the Y-chromosomes of men in Medellín are 95 percent European, while the mitochondrial DNA of the women is 95 percent Native American. Spanish men and Native American women created a new population--confirming the recorded history of the region.

The pattern of sexual exploitation by a dominant group seen in the preceding examples is not at all unusual in the human genetic record, says Reich’s frequent collaborator, Nick Patterson, a senior research scientist at the Broad Institute of MIT and Harvard. The Icelandic sagas record that the exiles who settled that island raided Scotland and Ireland, kidnapping Celtic women. And the genes corroborate this account. The mitochondrial DNA of the women is Celtic, the Y-chromosomes are Nordic

Fortunately, the science of the human past has progressed in these other areas no less than in the field of genetics. Innovations in archaeological analysis have had a profound impact

After the fall of the Roman empire, “you get this layer called ‘dark earth’” in the archaeological stratigraphy, he says. “People thought the empire fell and the cities turned into garden [plots]. That is how dark earth was understood up until about five years ago,

“In the Roman excavations,” says McCormick, “there were pots and stone buildings and columns.” But then suddenly you get a layer of nothing but dark, humus-looking soil. What actually happened, Galinié and others have found, is that people shifted to organic building materials. “They had thatched roofs and wooden houses, they didn’t have Roman garbage removal, and they just dumped the ashes and charcoal from their hearths out in the road and all of that compacted. It is extremely rich, extremely dense,

Like most young people, I thought I understood so much, when in fact I understood so little. My father knew exactly what he was doing when he raised that flag. He knew that our people’s contributions to building the richest and most powerful nation in the world were indelible, that the United States simply would not exist without us

Before the abolishment of the international slave trade, 400,000 enslaved Africans would be sold into America. Those individuals and their descendants transformed the lands to which they’d been brought into some of the most successful colonies in the British Empire

Black Americans have also been, and continue to be, foundational to the idea of American freedom

It is we who have been the perfecters of this democracy.

The United States is a nation founded on both an ideal and a lie. Our Declaration of Independence, signed on July 4, 1776, proclaims that “all men are created equal” and “endowed by their Creator with certain unalienable rights.” But the white men who drafted those words did not believe them to be true for the hundreds of thousands of black people in their midst

Through centuries of black resistance and protest, we have helped the country live up to its founding ideals. And not only for ourselves — black rights struggles paved the way for every other rights struggle, including women’s and gay rights, immigrant and disability rights.

Without the idealistic, strenuous and patriotic efforts of black Americans, our democracy today would most likely look very different — it might not be a democracy at all.

In every war this nation has waged since that first one, black Americans have fought — today we are the most likely of all racial groups to serve in the United States military.

the year 1619 is as important to the American story as 1776. That black Americans, as much as those men cast in alabaster in the nation’s capital, are this nation’s true “founding fathers.” And that no people has a greater claim to that flag than us.

Jefferson’s fellow white colonists knew that black people were human beings, but they created a network of laws and customs, astounding for both their precision and cruelty, that ensured that enslaved people would never be treated as such.

Enslavers could rape or murder their property without legal consequence. Enslaved people could own nothing, will nothing and inherit nothing. They were legally tortured, including by those working for Jefferson himself. They could be worked to death, and often were, in order to produce the highest profits for the white people who owned them.

Conveniently left out of our founding mythology is the fact that one of the primary reasons the colonists decided to declare their independence from Britain was because they wanted to protect the institution of slavery.

With the troops gone, white Southerners quickly went about eradicating the gains of Reconstruction. The systemic white suppression of black life was so severe that this period between the 1880s and the 1920 and ’30s became known as the Great Nadir, or the second slavery. Democracy would not return to the South for nearly a century.

we may never have revolted against Britain if the founders had not understood that slavery empowered them to do so; nor if they had not believed that independence was required in order to ensure that slavery would continue. It is not incidental that 10 of this nation’s first 12 presidents were enslavers, and some might argue that this nation was founded not as a democracy but as a slavocracy.

when it came time to draft the Constitution, the framers carefully constructed a document that preserved and protected slavery without ever using the word. In the texts in which they were making the case for freedom to the world, they did not want to explicitly enshrine their hypocrisy, so they sought to hide it

The Constitution contains 84 clauses. Six deal directly with the enslaved and their enslavement, as the historian David Waldstreicher has written, and five more hold implications for slavery. The Constitution protected the “property” of those who enslaved black people, prohibited the federal government from intervening to end the importation of enslaved Africans for a term of 20 years, allowed Congress to mobilize the militia to put down insurrections by the enslaved and forced states that had outlawed slavery to turn over enslaved people who had run away seeking refuge

The shameful paradox of continuing chattel slavery in a nation founded on individual freedom, scholars today assert, led to a hardening of the racial caste system. This ideology, reinforced not just by laws but by racist science and literature, maintained that black people were subhuman, a belief that allowed white Americans to live with their betrayal.

By the early 1800s, according to the legal historians Leland B. Ware, Robert J. Cottrol and Raymond T. Diamond, white Americans, whether they engaged in slavery or not, “had a considerable psychological as well as economic investment in the doctrine of black inferiority.”

The Supreme Court enshrined this thinking in the law in its 1857 Dred Scott decision, ruling that black people, whether enslaved or free, came from a “slave” race. This made them inferior to white people and, therefore, incompatible with American democracy

This belief, that black people were not merely enslaved but were a slave race, became the root of the endemic racism that we still cannot purge from this nation to this day. If black people could not ever be citizens, if they were a caste apart from all other humans, then they did not require the rights bestowed by the Constitution, and the “we” in the “We the People” was not a lie.

now Lincoln was blaming them for the war. “Although many men engaged on either side do not care for you one way or the other ... without the institution of slavery and the colored race as a basis, the war could not have an existence,” the president told them. “It is better for us both, therefore, to be separated.”

As W.E.B. Du Bois wrote, “Few men ever worshiped Freedom with half such unquestioning faith as did the American Negro for two centuries.” Black Americans had long called for universal equality and believed, as the abolitionist Martin Delany said, “that God has made of one blood all the nations that dwell on the face of the earth.” Liberated by war, then, they did not seek vengeance on their oppressors as Lincoln and so many other white Americans feared. They did the opposite.

The South, for the first time in the history of this country, began to resemble a democracy, with black Americans elected to local, state and federal offices. Some 16 black men served in Congress

These black officials joined with white Republicans, some of whom came down from the North, to write the most egalitarian state constitutions the South had ever seen. They helped pass more equitable tax legislation and laws that prohibited discrimination in public transportation, accommodation and housing. Perhaps their biggest achievement was the establishment of that most democratic of American institutions: the public school.

Led by black activists and a Republican Party pushed left by the blatant recalcitrance of white Southerners, the years directly after slavery saw the greatest expansion of human and civil rights this nation would ever see.

The many gains of Reconstruction were met with fierce white resistance throughout the South, including unthinkable violence against the formerly enslaved, wide-scale voter suppression, electoral fraud and even, in some extreme cases, the overthrow of democratically elected biracial governments.

Enslaved people could not legally marry. They were barred from learning to read and restricted from meeting privately in groups. They had no claim to their own children, who could be bought, sold and traded away from them on auction blocks alongside furniture and cattle

White Southerners of all economic classes, on the other hand, thanks in significant part to the progressive policies and laws black people had championed, experienced substantial improvement in their lives even as they forced black people back into a quasi slavery. As Waters McIntosh, who had been enslaved in South Carolina, lamented, “It was the poor white man who was freed by the war, not the Negroes.”

black Americans, simply by existing, served as a problematic reminder of this nation’s failings. White America dealt with this inconvenience by constructing a savagely enforced system of racial apartheid that excluded black people almost entirely from mainstream American life — a system so grotesque that Nazi Germany would later take inspiration from it for its own racist policies.

Despite the guarantees of equality in the 14th Amendment, the Supreme Court’s landmark Plessy v. Ferguson decision in 1896 declared that the racial segregation of black Americans was constitutional. With the blessing of the nation’s highest court and no federal will to vindicate black rights, starting in the late 1800s, Southern states passed a series of laws and codes meant to make slavery’s racial caste system permanent by denying black people political power, social equality and basic dignity.

This caste system was maintained through wanton racial terrorism. And black veterans like Woodard, especially those with the audacity to wear their uniform, had since the Civil War been the target of a particular violence

As Senator James K. Vardaman of Mississippi said on the Senate floor during World War I, black servicemen returning to the South would “inevitably lead to disaster.” Giving a black man “military airs” and sending him to defend the flag would bring him “to the conclusion that his political rights must be respected.”

Many white Americans saw black men in the uniforms of America’s armed services not as patriotic but as exhibiting a dangerous pride. Hundreds of black veterans were beaten, maimed, shot and lynched

During the height of racial terror in this country, black Americans were not merely killed but castrated, burned alive and dismembered with their body parts displayed in storefronts. This violence was meant to terrify and control black people, but perhaps just as important, it served as a psychological balm for white supremacy: You would not treat human beings this way

If the formerly enslaved and their descendants became educated, if we thrived in the jobs white people did, if we excelled in the sciences and arts, then the entire justification for how this nation allowed slavery would collapse

Free black people posed a danger to the country’s idea of itself as exceptional; we held up the mirror in which the nation preferred not to peer. And so the inhumanity visited on black people by every generation of white America justified the inhumanity of the past.

As the centennial of slavery’s end neared, black people were still seeking the rights they had fought for and won after the Civil War: the right to be treated equally by public institutions, which was guaranteed in 1866 with the Civil Rights Act; the right to be treated as full citizens before the law, which was guaranteed in 1868 by the 14th Amendment; and the right to vote, which was guaranteed in 1870 by the 15th Amendment.

In response to black demands for these rights, white Americans strung them from trees, beat them and dumped their bodies in muddy rivers, assassinated them in their front yards, firebombed them on buses, mauled them with dogs, peeled back their skin with fire hoses and murdered their children with explosives set off inside a church.

For the most part, black Americans fought back alone. Yet we never fought only for ourselves. The bloody freedom struggles of the civil rights movement laid the foundation for every other modern rights struggle.

This nation’s white founders set up a decidedly undemocratic Constitution that excluded women, Native Americans and black people, and did not provide the vote or equality for most Americans. But the laws born out of black resistance guarantee the franchise for all and ban discrimination based not just on race but on gender, nationality, religion and ability

It was the civil rights movement that led to the passage of the Immigration and Nationality Act of 1965, which upended the racist immigration quota system intended to keep this country white

to this day, black Americans, more than any other group, embrace the democratic ideals of a common good. We are the most likely to support programs like universal health care and a higher minimum wage, and to oppose programs that harm the most vulnerable. For instance, black Americans suffer the most from violent crime, yet we are the most opposed to capital punishment

Our unemployment rate is nearly twice that of white Americans, yet we are still the most likely of all groups to say this nation should take in refugees

as much democracy as this nation has today, it has been borne on the backs of black resistance. Our founding fathers may not have actually believed in the ideals they espoused, but black people did

“Out of the ashes of white denigration, we gave birth to ourselves.” For as much as white people tried to pretend, black people were not chattel. And so the process of seasoning, instead of erasing identity, served an opposite purpose: In the void, we forged a new culture all our own.

Today, our very manner of speaking recalls the Creole languages that enslaved people innovated in order to communicate both with Africans speaking various dialects and the English-speaking people who enslaved them.

Our style of dress, the extra flair, stems back to the desires of enslaved people — shorn of all individuality — to exert their own identity

The improvisational quality of black art and music comes from a culture that because of constant disruption could not cling to convention.

Black naming practices, so often impugned by mainstream society, are themselves an act of resistance. Our last names belong to the white people who once owned us. That is why the insistence of many black Americans, particularly those most marginalized, to give our children names that we create, that are neither European nor from Africa, a place we have never been, is an act of self-determination

We were told once, by virtue of our bondage, that we could never be American. But it was by virtue of our bondage that we became the most American of all.

It is common, still, to point to rates of black poverty, out-of-wedlock births, crime and college attendance, as if these conditions in a country built on a racial caste system are not utterly predictable. But crucially, you cannot view those statistics while ignoring another: that black people were enslaved here longer than we have been free.

Black people suffered under slavery for 250 years; we have been legally “free” for just 50. Yet in that briefest of spans, despite continuing to face rampant discrimination, and despite there never having been a genuine effort to redress the wrongs of slavery and the century of racial apartheid that followed, black Americans have made astounding progress, not only for ourselves but also for all Americans

Out of our unique isolation, both from our native cultures and from white America, we forged this nation’s most significant original culture. In turn, “mainstream” society has coveted our style, our slang and our song, seeking to appropriate the one truly American culture as its own.

racial disparities in cases and outcomes, researchers said, reflect what happens when a viral pandemic is layered on top of entrenched inequalities.

The data, researchers said, is partly explained by factors that could make black Americans more vulnerable in any outbreak: They are less likely to be insured, more likely to already have health conditions and more likely to be denied testing and treatment.

There is also the highly infectious nature of the virus in a society where black Americans disproportionately hold jobs that do not allow them to stay at home

“If you walk outside and see who is actually still working,” said Elaine Nsoesie, of Boston University’s School of Public Health, “the data don’t seem surprising.”

Two of the Black men on the jury are not African Americans but, rather, Black immigrants. During questioning, they expressed the kind of moderate views on policing and race relations that defense attorney Eric Nelson generally found acceptable as he considered which potential jurors to strike and which to allow.

None of the Black jurors ultimately chosen for the panel spoke extensively about personal experiences with racism or about having had overtly negative interactions with police. Several said they had a healthy respect for law enforcement.

In recent years, she has paid special attention to how professed support for the Black Lives Matter movement has gotten many Black people struck from juries. That did not seem to be the case during jury selection for the Chauvin trial. Several jurors who expressed at least some support for the movement were seated on the jury — a sign of progress, Chakravarti said.

Despite those experiences, Juror 76 assured the judge and attorneys that he could put his opinions aside and decide the case against Chauvin fairly and based only on the evidence. He said he could foresee himself casting a not-guilty vote if the evidence required it. He had also served on a jury before. Defense attorney Nelson struck him nonetheless, citing the juror's bias against the Minneapolis police.

That decision elicited concern from Steve Schleicher, the lawyer leading jury selection for the prosecution, who disagreed that the juror's comments revealed anti-police bias. Instead, he said, they were a simple reflection of the juror's daily lived experience as a Black man.

The fate of Juror 76 highlighted a tension that often exists in jury selection, especially in cases in which issues of race loom large. The experiences that come with being Black in America are often enough to get jurors struck from a case, said Sonali Chakravarti, a Wesleyan University professor who has studied the role of race in jury selection.

That was in contrast to one potential juror — an African American man and former soldier — who said he had lived in the neighborhood where Floyd was killed and said police in the area were known to antagonize residents. The man, identified only by his juror number, 76, also spoke of experiencing racism on a daily basis and recounted seeing Black acquaintances sentenced to prison for crimes while white ones often got a "slap on the wrist."

On one hand, that the defense would strike people with negative views of police is understandable, given Nelson's responsibility to seat a jury favorable to his client. The prosecution in the Chauvin case also struck white jurors who expressed police-friendly views or who had negative opinions of Black Lives Matter or the protests that followed Floyd's killing.But Chakravarti said that given history, it is appropriate to apply greater scrutiny when Black jurors are struck.

Given Hennepin County's overwhelmingly white jury pool, that four Black and two multiracial people made it onto the Chauvin jury is a considerable feat, even if their expressed views on race and police are more conservative than those of countless African Americans who've marched for racial justice in the last year.

In a column, Mary Moriarty, the former chief public defender for Minneapolis, said she had watched the questioning of Juror 76 and, though she expected him to be struck, had hoped he wouldn't be.She said his fate was a reminder that the jury selection process should be reformed to ensure more African Americans have a fair shot to serve on juries.

Those who died, in some cases, were commemorated collectively on memorials rather than with their own individual headstones or grave markers, like their European counterparts were. In other cases, soldiers who were missing had their names recorded in registers rather than in stone.

The war grave findings come as British institutions grapple with a reckoning over racial injustice, fueled by Black Lives Matter protests that erupted across the country last summer.

Statues of slave traders have been torn down in some cities in Britain, and museums in the country have been working to highlight links to slavery and colonialism in their exhibits.

“No apology can ever make up for the indignity suffered by The Unremembered,” Mr. Lammy said on Twitter in response to the inquiry. But recognition that the commission had failed to treat Black African and other ethnic minority soldiers the same as others was a “watershed moment,” he said

Responding to the findings, the Commonwealth War Graves Commission apologized for “historic failings” and said that it was fully committed to delivering on a series of recommendations made in the report.

The British defense secretary, Ben Wallace, apologized on behalf of the government on Thursday. “There can be no doubt that prejudice played a part in some of the commissioners’ decisions,” he said in Parliament.

But Kehinde Andrews, professor of Black Studies at Birmingham City University, said “It’s really farcical that in the 21st century, now, they want to apologize.”

Many Britons were unaware that nonwhite colonial subjects were involved in the empire’s wars, and that was because of gaps in the history that is taught in schools, Professor Andrews said. “If government institutions were serious, you have to fundamentally rebuild the school curriculum from scratch,” he added.

“This was 100 years ago,” he said, adding that the current accounting of past wrongs was “too little, too late.”
