“Celtic” languages were not imports to the region but instead were developed somewhere in the British Isles or the Iberian Peninsula — and then spread eastward into continental Europe.

His doubts about the traditional view arose as he was studying inscriptions on artifacts from southern Portugal. The inscriptions on those artifacts strongly resembled the languages known as Celtic, yet they dated as far back as 700 B.C. This placed Celtic languages far from the Celt homelands in the middle of Europe at a very, very early date.

“What it shows is that the language that became Irish was already out there — before 700 B.C. and before the Iron Age,” Koch said. “It just didn’t fit with the traditional theory of Celtic spreading west to Britain and Iberia.”

What’s also been lost are the social institutions and cultural values that made it possible to have self-respect amid hardship — to say, “I may not make a lot of money, but people can count on me. I’m loyal, tough, hard-working, resilient and part of a good community.”

He describes a culture of intense group loyalty.

there can be intense parochialism. “We do not like outsiders,” Vance writes, “or people who are different from us, whether difference lies in how they look, how they act, or, most important, how they talk.”

Sweden’s economic and political model depends on Pax Americana, the set of American-written and American-backed rules that have governed transatlantic commerce and politics for 70 years — and they fear Trump will bring Pax Americana crashing down. Nor are they alone: Variations of this conversation are taking place in every European capital and many Asian capitals too.

In the last four decades, centrist or modernist Islamists, most of whom accept the rules of the political game, brilliantly positioned themselves as the alternative to the failed secular "authoritarian bargain". They invested considerable capital in building social networks on the national and local levels, including non-government professional civil society associations, welfare, and family ties. In contrast to their secular-minded opponents, Islamists have mastered the art of local politics and built a formidable political machine that repeatedly has proved able to deliver the vote. Islamists’ recent parliamentary victories are not surprising, because they had paid their dues and earned the trust of voters

Islamist parties are increasingly becoming "service" parties: an acknowledgment that political legitimacy and the likelihood of re-election rests on the ability to deliver jobs, economic growth, and to demonstrate transparency. This factor introduces a huge degree of pragmatism in their policies. The example of Turkey, especially its economic success, has had a major impact on Arab Islamists, many of whom would like to emulate the Turkish model. The Arab Islamists have, in other words, understood the truth of the slogan, "It is the economy, stupid!" The Turkish model, with the religiously observant provincial bourgeoisie as its kingpin, also acts as a reminder that Islam and capitalism are mutually reinforcing and compatible.

It is notable that the Islamists' economic agenda does not espouse a distinctive "Islamic" economic model. This is unsurprising, however, as an Islamic economic model does not exist

The first evidence to raise significant questions about the Clovis model emerged in the late 1970s, when the anthropologist Tom Dillehay came across a prehistoric campsite in southern Chile called Monte Verde. Radiocarbon dating of the site suggested that the first campfires were lighted there, all the way at the southern tip of South America, well before the first Clovis tools were made

Professor Waters announced finding dozens of stone tools along a Texas creekbed. After using a technique that measures the last time the dirt around the stones was exposed to light, Professor Waters concluded, in a paper in Science, that the site was at least 15,000 years old — which would make it the earliest reliably dated site in the Americas.

Having compared the DNA of modern American Indians with that of groups living in Asia today, scholars have estimated that the last common ancestor of the two peoples probably lived between 16,000 and 20,000 years ago. That figure doesn’t square with the arrival of the Clovis people from Asia only 13,500 years ago.

Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.

Our Berkeley Earth approach used sophisticated statistical methods developed largely by our lead scientist, Robert Rohde, which allowed us to determine earth land temperature much further back in time. We carefully studied issues raised by skeptics: biases from urban heating (we duplicated our results using rural data alone), from data selection (prior groups selected fewer than 20 percent of the available temperature stations; we used virtually 100 percent), from poor station quality (we separately analyzed good stations and poor ones) and from human intervention and data adjustment (our work is completely automated and hands-off). In our papers we demonstrate that none of these potentially troublesome effects unduly biased our conclusions.

The historic temperature pattern we observed has abrupt dips that match the emissions of known explosive volcanic eruptions; the particulates from such events reflect sunlight, make for beautiful sunsets and cool the earth’s surface for a few years. There are small, rapid variations attributable to El Niño and other ocean currents such as the Gulf Stream; because of such oscillations, the “flattening” of the recent temperature rise that some people claim is not, in our view, statistically significant. What has caused the gradual but systematic rise of two and a half degrees? We tried fitting the shape to simple math functions (exponentials, polynomials), to solar activity and even to rising functions like world population. By far the best match was to the record of atmospheric carbon dioxide, measured from atmospheric samples and air trapped in polar ice.

Education will end up being dominated by a few huge incumbents.  As we see with Facebook and Twitter and, well, almost everything, the internet offers huge returns to scale, and substantial network effects.

Online education will kill the liberal arts degree.

 The important aspect for this discussion is that what they teach is hard to test efficiently.  There's enormous variation in grading of, say, English papers, and even if it were easier to standardize, that grading requires hours of expensive labor.

The biggest threat those of us working in colleges and universities face isn’t video lectures or online tests. It’s the fact that we live in institutions perfectly adapted to an environment that no longer exists.

Decades of rising revenue meant we could simultaneously become the research arm of government and industry, the training ground for a rapidly professionalizing workforce, and the preservers of the liberal arts tradition. Even better, we could do all of this while increasing faculty ranks and reducing the time senior professors spent in the classroom. This was the Golden Age of American academia.

Rising costs and falling subsidies have driven average tuition up over 1000% since the 1970s.

In an assertion reminiscent of the many denials over the years by the officers and their lawyers, Mr. Erdogan’s office released a statement saying that the recordings released on Monday were “a product of an immoral montage that is completely false.”

Many of the prosecutors and investigators in both cases — the corruption inquiry and the old military trials — are followers of Fethullah Gulen,

Recently, under pressure from the government, Turkish lawmakers voted to abolish the special courts in which the officers were tried, a significant step toward new trials. Variations of these courts, set up under antiterrorism laws, have been in place in Turkey since the 1970s. They operate under special rules that allow secret witnesses and wiretaps that would not be admissible in regular courts.

In the year of the 150th anniversary of the Emancipation Proclamation, Copperhead presents us with a false depiction of the Copperheads as principled men of peace instead of what they were -- often violent and always racist defenders of slavery, secession, and the Confederacy. Copperhead is propaganda for an old variation of the neo-Confederate Lost Cause myth, that the root of the Civil War was not slavery and the slave power, but an aggressive, power-mad North seeking to tyrannize, by unconstitutional means, a benign and chivalrous South. The Lost Cause myth was at its heart not a matter of a differing interpretation, but of the falsification and suppression of history in order to vindicate the Confederacy and later to justify Jim Crow.

As Tocqueville observed after visiting the new republic, the widespread perception that anyone can get ahead creates a presumption that everyone has an obligation to at least try.

two centuries later, both the perception and the sense of obligation that follows are still firmly in place. According to the World Values Survey, while 60 percent of Europeans say they think “the poor are trapped in poverty,” only 29 percent of Americans think so. Instead, 60 percent of Americans think “the poor are lazy,” compared with just 26 percent of Europeans.

Vast inequality may be acceptable to most citizens if anyone, or at least anyone’s grandchild, has a fair shot at the top. But if wealth and poverty simply perpetuate themselves within families, ever wider inequality becomes ever harder to justify. In America, the debate about inequality is, inevitably, also a debate about mobility.

I was shocked that no one had ever helped me understand that while the creation of Israel was a magnificent event for the Jewish people, it devastated Palestinian life. I had never considered the impact of war and displacement — as well as occupation and settlement expansion — on Palestinian communities. Learning about Palestinian culture was a transformative experience for me

Jews must grapple with Palestinian perspectives because we can’t wish Palestinians away or pretend they don’t exist. We have a moral obligation to listen carefully to their stories and try to comprehend what they have endured as a result of war and displacement. If we want a peaceful resolution to the Israeli-Palestinian conflict, we must engage directly with Palestinians – not by criticizing or attacking them, but by genuinely trying to understand their experiences.

Educators should also help their students cultivate understanding, respect and compassion for both Israelis and Palestinians. Often we don’t teach our children about the Palestinians because we don’t see them as central to our people’s stories. Yet Jews and Palestinians are linked together through a complex history, present conflict and unknown future.

a closer look at the forces that drive the relentless pace at elite companies suggests that — however much the most sought-after employers in the country may be changing their official policies — brutal competition remains an inescapable component of workers’ daily lives. In some ways it’s getting worse.

the basic problem is that the rewards for ascending to top jobs at companies like Netflix and Goldman Sachs are not just enormous, they are also substantially greater than at companies in the next tier down. As a result, far more people are interested in these jobs than there are available slots, leading to the brutal competition

Grueling competition remains perhaps the defining feature of the upper echelon in today’s white-collar workplace.

some 200 years ago, dog breeding was initiated in England, generating the highly inbred and distinctive lines we encounter today.

Breeding programs can only yield as much variation as is harbored in the gene pool, and the dog gene pool proved to be a gold mine.

organisms with higher mutation rates are said to be more evolvable than organisms with lower mutation rates.

he replied to claims that global warming was a myth, declaring that the real myth was that “natural resources and the ability of the earth’s habitable regions to absorb the impacts of human activities are limitless.”

Bubbles of ancient air trapped by glaciers and ice sheets have been tested, and they show that over the past 800,000 years, the amount of carbon dioxide in the air oscillated between roughly 200 and 300 parts per million. Just before the Industrial Revolution, the level was about 280 parts per million and had been there for several thousand years.

carbon dioxide as the master control knob of the earth’s climate. He said that because the wobbles in the earth’s orbit were not, by themselves, big enough to cause the large changes of the ice ages, the situation made sense only when the amplification from carbon dioxide was factored in.

In a book to be published in April, “The Origins of Political Order,” Francis Fukuyama of Stanford University presents a sweeping new overview of human social structures throughout history, taking over from where Dr. Wilson’s ambitious synthesis left off.

he explicitly assumes that human social nature is universal and is built around certain evolved behaviors like favoring relatives, reciprocal altruism, creating and following rules, and a propensity for warfare.

Because of this shared human nature, with its biological foundation, “human politics is subject to certain recurring patterns of behavior across time and across cultures,” he writes. It is these worldwide patterns he seeks to describe in an analysis that stretches from prehistoric times to the French Revolution.

Educators, not just those in thrall to teaching to “the test,” share plenty of the blame for “raising young people who are, by and large, historically illiterate,” as David McCullough called the problem

it’s because many schools no longer stress “civics,” or some variation of it. Why? Students complain that it’s boring, or the standards are too demanding. Civics, said Burns, is “the operating system” for citizenry; if you know how government is constructed, it’s no longer a complicated muddle, but a beautiful design.

Americans tended to be “ahistorical” — that is, we choose to forget the context of our past, perhaps as a way for a fractious nation of immigrants to get along.

South Dakota is on the cusp of becoming the first state in the nation to require public school students to use facilities like bathrooms based on their “chromosomes and anatomy” at birth.

The so-called “bathroom bill,” which passed the state House in early February and is being debated by the state Senate Tuesday, marks a revival of the charged fights that played out in states across the country in 2015.

At least five other states have considered similar “bathroom bills” this session, and scores of other measures that LGBT rights advocates consider discriminatory are pending in legislatures around the U.S.

PALMAS, Brazil — The first World Indigenous Games closed Saturday night with a pumping ceremony that brought together nearly 2,000 participants from more than two dozen countries for a monumental extravaganza.

Palmas, a sunbaked outpost in the geographical heart of Brazil, and the 5,000-seat arena was packed well beyond capacity for the spectacle.

With delegations from as far afield as Ethiopia and New Zealand and two dozen indigenous peoples from across Brazil, the games produced nine frenetic days of compet

The most striking thing about Bret Stephens’s inaugural column in the New York Times was not its banal defense of the principle of scientific skepticism, but its general lameness. Rereading it this week, it is striking how modest its claims were. They essentially came to this: “Claiming total certainty about the science traduces the spirit of science and creates openings for doubt whenever a climate claim proves wrong. Demanding abrupt and expensive changes in public policy raises fair questions about ideological intentions. Censoriously asserting one’s moral superiority and treating skeptics as imbeciles and deplorables wins few converts.”

The denialists, in other words, have nothing left
