Hawaii: Where Evolution Can Be Surprisingly Predictable - The Atlantic - 0 views

evolution hawaii science research

shared by knudsenlu on 11 Mar 18 - No Cached
  • Situated around 2,400 miles from the nearest continent, the Hawaiian Islands are about as remote as it’s possible for islands to be. In the last 5 million years, they’ve been repeatedly colonized by far-traveling animals, which then diversified into dozens of new species. Honeycreeper birds, fruit flies, carnivorous caterpillars ... all of these creatures reached Hawaii, and evolved into wondrous arrays of unique forms.
  • The most spectacular of these spider dynasties, Gillespie says, are the stick spiders. They’re so-named because some of them have long, distended abdomens that make them look like twigs. “You only see them at night, walking around the understory very slowly,” Gillespie says. “They’re kind of like sloths.” Murderous sloths, though: Their sluggish movements allow them to sneak up on other spiders and kill them.
  • Gillespie has shown that the gold spiders on Oahu belong to a different species from those on Kauai or Molokai. In fact, they’re more closely related to their brown and white neighbors from Oahu. Time and again, these spiders have arrived on new islands and evolved into new species—but always in one of three basic ways. A gold spider arrives on Oahu, and diversified into gold, brown, and white species. Another gold spider hops across to Maui and again diversified into gold, brown, and white species. “They repeatedly evolve the same forms,” says Gillespie.

  • Gillespie has seen this same pattern before, among Hawaii’s long-jawed goblin spiders. Each island has its own representatives of the four basic types: green, maroon, small brown, and large brown. At first, Gillespie assumed that all the green species were related to each other. But the spiders’ DNA revealed that the ones that live on the same islands are most closely related, regardless of their colors. They too have hopped from one island to another, radiating into the same four varieties wherever they land.
  • One of the most common misunderstandings about evolution is that it is a random process. Mutations are random, yes, but those mutations then rise and fall in ways that are anything but random. That’s why stick spiders, when they invade a new island, don’t diversify into red species, or zebra-striped ones. The environment of Hawaii sculpts their bodies in a limited number of ways.
  • Gillespie adds that there’s an urgency to this work. For millions of years, islands like Hawaii have acted as crucibles of evolution, allowing living things to replay evolution’s tape in the way that Gould envisaged. But in a much shorter time span, humans have threatened the results of those natural experiments. “The Hawaiian islands are in dire trouble from invasive species, and environmental modifications,” says Gillespie. “And you have all these unknown groups of spiders—entire lineages of really beautiful, charismatic animals, most of which are undescribed.”

  • As soon as you hit Google’s territorial waters, you came under our jurisdiction, our terms of service. Our laws–or lack thereof–apply here. By boarding our self-driving boat you granted us the right to all feedback you provide during your journey. This includes the chemical composition of your sweat.
  • Unified logins let us get to know our audience in ways we never could before. They gave us their locations so that we might better tell them if it was raining outside. They told us where they lived and where they wanted to go so that we could deliver a more immersive map that better anticipated what they wanted to do–it let us very literally tell people what they should do today. As people began to see how very useful Google Now was, they began to give us even more information. They told us to dig through their e-mail for their boarding passes–Imagine if you had to find it on your own!–they finally gave us permission to track and store their search and web history so that we could give them better and better Cards. And then there is the imaging. They gave us tens of thousands of pictures of themselves so that we could pick the best ones–yes we appealed to their vanity to do this: We’ll make you look better and assure you present a smiling, wrinkle-free face to the world–but it allowed us to also stitch together three-dimensional representations. Hangout chats let us know who everybody’s friends were, and what they had to say to them. Verbal searches gave us our users’ voices. These were intermediary steps. But it let us know where people were at all times, what they thought, what they said, and of course how they looked. Sure, Google Now could tell you what to do.
  • “We learned so much about regulation with Google Health. It turns out, the government has rules about health records, and that people care about these rules for some reason. So we began looking around for ways to avoid regulation. For example, government regulation meant it was much easier to experiment with white space in Kenya than in the United States. So we started thinking: What if the entire world looked more like Kenya? Or, even better, Somalia? Places where there are no laws. We haven’t adapted mechanisms to deal with some of our old institutions like the law. We aren’t keeping up with the rate of change we caused through technology. If you look at the laws we have, they’re very old. A law can’t be right if it’s 50 years old. Like, it’s before the Internet

  • I don’t want this,” I stammered, removing the glasses. “Sure you do, you just aren’t aware of that yet. For many years now, we’ve looked at everything you’ve looked at online. Everything. We know what you want, and when you want it, down to the time of day. Why wait for you to request it? And in fact, why wait for you to discover that you even want to request it? We can just serve it to you.”
  • “These are Google Spiders. They’ve crawled the entire island, and now we’re ready to release them globally. We’re sending them everywhere, so that we can make a 3D representation of the entire planet, and everyone on it. We aren’t just going to recreate the planet, though–we’re going to make it better.” “Governments are too focused on democracy and rule of law. On Google Island, we’ve found those things to be distractions. If democracy worked so well, if a majority public opinion made something right, we would still have Jim Crow laws and Google Reader. We believe we can fix the world’s problems with better math. We can tear down the old and rebuild it with the new. Imagine Minecraft. Now imagine it photorealistic, and now imagine yourself living there, or at least, your Google Being living there. We already have the information. All we need is an invitation. This is the inevitable and logical end point of Google Island: a new Google Earth.”

  • Piper, Mijares and their team published a description of the foot bone in 2010. They knew it was the oldest human remain in the Philippines, dated to 67,000 years ago, based on the amount of the radioactive element uranium in the fossil
  • Mijares returned to Callao Cave and uncovered more remains in 2011 and 2015. All told, the scientists pulled a dozen fossilized parts from the cave — teeth, a thigh bone, finger bones and foot bones, representing three individuals. Attempts to extract DNA from the remains were unsuccessful.
  • The body parts are diminutive, suggesting Homo luzonensis grew no more than four feet tall. Its molars have modern shapes. The way its leg muscle attached to its thigh bone is “distinctively human,”
  • ...12 more annotations...
  • The bones in its hands and feet are curved, “spitting images” of the toes and finger bones that belonged to the ancient Australopithecus, Piper said. These hominids, such as the 3 million-year-old Australopithecus afarensis Lucy, had digits well-suited for climbing.
  • This species lived at the same time as humans with modern anatomy, who first appeared in the fossil record 200,000 years ago (or perhaps as long as 350,000 years ago). ″We continue to realize that few thousands of years back in time, H. sapiens was definitely not alone on Earth,”
  • Though these fossils are the oldest in the Philippines, evidence for habitation is even older; 700,000 years ago, ancient butchers on Luzon carved up a rhinoceros with stone tools. Which species did the butchering is unknown.
  • A few “mammal species you find on Luzon appear to have come from the mainland,” Piper said. The Asian continent is 400 or more miles away through the Luzon strait. But in the Middle Pleistocene, when glacial sheets locked up vast amounts of water, sea levels dropped by as much as 400 feet, Piper said.
  • “I would just say that when humans could see land or they could smell it or they knew the signs, that birds were coming from it, they sought it out,” he said. “That’s not a Homo sapiens trait. It’s something our ancestors and extinct relatives had.”
  • The cartoon version of evolution, in which a hunched ape becomes a tall and jaunty biped, suggests a journey with a destination. The reality is messier,
  • An island’s confines can rapidly spark evolutionary change; Charles Darwin saw this in finches’ beaks.
  • “Isolation plays games,” Potts said. Homo floresiensis showed anthropologists that an island could be an “odd little laboratory of human evolution,” he said. These bones reinforce that lesson.
  • “It’s beginning to look like the evolutionary process is really fluid,” Potts said. “And it’s surprising that it is so fluid where each species of Homo may actually be a history or a record.” The result is a fusion of the modern and ancient: molars that could be yours alongside toes with millions-year-old curves.
  • Fifteen years ago, Hawks said, anthropologists chalked up the worldwide success of Homo sapiens to our modern anatomy. These new discoveries, in far-flung corners, suggest exceptionalism is not built into our brains or skeletons.
  • “The archaeological record is now showing us that ancient human forms were much more adaptable, and I would say clever, than we imagined,”
  • “This isn’t ‘Flowers for Algernon,’ where, suddenly, we’re super smart and everyone else in the world is behind us.” Scientists are now plumbing genomes for other clues to Homo sapiens’ survival, looking at our metabolisms or resistance to disease, he said. “I’d say the doors have opened, and we haven’t figured out where they lead.”

  • Before the advent of Caribbean genetic studies, archaeologists provided most of the clues about the origins of people in the region. The first human residents of the Caribbean appear to have lived mostly as hunter-gatherers, catching game on the islands and fishing at sea while also maintaining small gardens of crops.
  • Archaeologists have discovered a few burials of those ancient people. Starting in the early 2000s, geneticists managed to fish out a few tiny bits of preserved DNA in their bones. Significant advances in recent years have made it possible to pull entire genomes from ancient skeletons.
  • “We went from zero full genomes two years ago to over 200 now,”
  • ...17 more annotations...
  • The genes of the oldest known residents of the Caribbean link them with the earliest populations that settled in Central and South America.
  • Part of the problem is that scientists have yet to find ancient DNA in the Caribbean that is more than 3,000 years old
  • The other problem is that ancient DNA is still scarce on the Caribbean coast of the mainland.
  • About 2,500 years ago, the archaeological record shows, there was a drastic shift in the cultural life of the Caribbean. People started living in bigger settlements, intensively farming crops like maize and sweet potatoes. Their pottery became more sophisticated and elaborate. For archaeologists, the change indicates the end of what they call the Archaic Age and the start of a Ceramic Age.
  • The skeletons from the Ceramic Age largely shared a new genetic signature. Their DNA links them to small tribes still living today in Colombia and Venezuela.
  • We don’t know a lot about these languages, although some words have managed to survive. Hurricane, for example, comes from hurakán, the Taino name for the god of storms.
  • The people bearing Ceramic Age ancestry came to dominate the Caribbean, with almost no interbreeding between the two groups.
  • These words bear a striking resemblance to words from a family of languages in South America called Arawak. The DNA of the Ceramic Age Caribbeans most closely resembles that of living Arawak speakers.
  • the new DNA findings had surprised him in many ways, giving him a host of new questions to investigate.
  • Over the course of the Ceramic Age, for example, strikingly new pottery styles emerged every few centuries. Researchers have long guessed that those shifts reflect the arrival of new groups of people in the islands. The ancient DNA doesn’t support that idea, though. There’s a genetic continuity through those drastic cultural changes. It appears that the same group of people in the Caribbean went through a series of major social changes that archaeologists have yet to explain.
  • Dr. Reich and his fellow geneticists also discovered family ties that spanned the Caribbean during the Ceramic Age. They found 19 pairs of people on different islands who shared identical segments of DNA — a sign that they were fairly close relatives. In one case, they found long-distance cousins from the Bahamas and Puerto Rico, separated by over 800 miles.
  • “The original idea was that people start in one place, they establish a colony someplace else, and then they just cut all ties to where they came from,” Dr. Keegan said. “But the genetic evidence is suggesting that these ties were maintained over a long period of time.”
  • Rather than being made up of isolated communities, in other words, the Caribbean was a busy, long-distance network that people regularly traveled by dugout canoe. “The water is like a highway,”
  • The genetic variations also allowed Dr. Reich and his colleague to estimate the size of the Caribbean society before European contact. Christopher Columbus’s brother Bartholomew sent letters back to Spain putting the figure in the millions
  • The DNA suggests that was an exaggeration: the genetic variations imply that the total population was as low as the tens of thousands.
  • now, with a population of about 44 million people, the Caribbean may contain more Taino DNA than it did in 1491.
  • Dr. Aviles and his colleagues have uploaded the ancient Caribbean genomes to a genealogical database called GEDMatch. With the help of genealogists, people can compare their own DNA to the ancient genomes. They can see the matching stretches of genetic material that reveal their relatedness.

  • It wasn’t long after Henry David Inglis arrived on the island of Jersey, just northwest of France, that he heard the old story. Locals eagerly told the 19th-century Scottish travel writer how, in a bygone age, their island had been much more substantial, and that folks used to walk to the French coast. The only hurdle to their journey was a river—one easily crossed using a short bridge.
  • there had been a flood. A big one. Between roughly 15,000 and 6,000 years ago, massive flooding caused by melting glaciers raised sea levels around Europe. That flooding is what eventually turned Jersey into an island.
  • Rather than being a ridiculous claim not worthy of examination, perhaps the old story was true—a whisper from ancestors who really did walk through now-vanished lands
  • ...8 more annotations...
  • That’s exactly what the geographer Patrick Nunn and the historian Margaret Cook at the University of the Sunshine Coast in Australia have proposed in a recent paper.
  • In their work, the pair describe colorful legends from northern Europe and Australia that depict rising waters, peninsulas becoming islands, and receding coastlines during that period of deglaciation thousands of years ago. Some of these stories, the researchers say, capture historical sea-level rise that actually happened—often several thousand years ago. For scholars of oral history, that makes them geomyths.
  • “The first time I read an Aboriginal story from Australia that seemed to recall the rise of sea levels after the last ice age, I thought, No, I don’t think this is correct,” Nunn says. “But then I read another story that recalled the same thing.
  • For Jo Brendryen, a paleoclimatologist at the University of Bergen in Norway who has studied the effects of deglaciation in Europe following the end of the last ice age, the idea that traditional oral histories preserve real accounts of sea-level rise is perfectly plausible.
  • During the last ice age, he says, the sudden melting of ice sheets induced catastrophic events known as meltwater pulses, which caused sudden and extreme sea-level rise. Along some coastlines in Europe, the ocean may have risen as much as 10 meters in just 200 years. At such a pace, it would have been noticeable to people across just a few human generations.
  • “These are stories based in trauma, based in catastrophe.”
  • That, he suggests, is why it may have made sense for successive generations to pass on tales of geological upheaval. Ancient societies may have sought to broadcast their warning: Beware, these things can happen!
  • the old stories still have things to teach us. As Nunn says, “The fact that our ancestors have survived those periods gives us hope that we can survive this.”

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.
  • ...9 more annotations...
  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.

  • And that, many aviation and automation experts have concluded, is a problem. Overuse of automation erodes pilots’ expertise and dulls their reflexes,
  • No one doubts that autopilot has contributed to improvements in flight safety over the years. It reduces pilot fatigue and provides advance warnings of problems, and it can keep a plane airborne should the crew become disabled. But the steady overall decline in plane crashes masks the recent arrival of “a spectacularly new type of accident,”
  • “We’re forgetting how to fly.”
  • The experience of airlines should give us pause. It reveals that automation, for all its benefits, can take a toll on the performance and talents of those who rely on it. The implications go well beyond safety. Because automation alters how we act, how we learn, and what we know, it has an ethical dimension. The choices we make, or fail to make, about which tasks we hand off to machines shape our lives and the place we make for ourselves in the world.
  • What pilots spend a lot of time doing is monitoring screens and keying in data. They’ve become, it’s not much of an exaggeration to say, computer operators.
  • Examples of complacency and bias have been well documented in high-risk situations—on flight decks and battlefields, in factory control rooms—but recent studies suggest that the problems can bedevil anyone working with a computer
  • That may leave the person operating the computer to play the role of a high-tech clerk—entering data, monitoring outputs, and watching for failures. Rather than opening new frontiers of thought and action, software ends up narrowing our focus.
  • A labor-saving device doesn’t just provide a substitute for some isolated component of a job or other activity. It alters the character of the entire task, including the roles, attitudes, and skills of the people taking part.
  • when we work with computers, we often fall victim to two cognitive ailments—complacency and bias—that can undercut our performance and lead to mistakes. Automation complacency occurs when a computer lulls us into a false sense of security. Confident that the machine will work flawlessly and handle any problem that crops up, we allow our attention to drift.
  • Automation bias occurs when we place too much faith in the accuracy of the information coming through our monitors. Our trust in the software becomes so strong that we ignore or discount other information sources, including our own eyes and ears
  • Automation is different now. Computers can be programmed to perform complex activities in which a succession of tightly coordinated tasks is carried out through an evaluation of many variables. Many software programs take on intellectual work—observing and sensing, analyzing and judging, even making decisions—that until recently was considered the preserve of humans.
  • Automation turns us from actors into observers. Instead of manipulating the yoke, we watch the screen. That shift may make our lives easier, but it can also inhibit the development of expertise.
  • Since the late 1970s, psychologists have been documenting a phenomenon called the “generation effect.” It was first observed in studies of vocabulary, which revealed that people remember words much better when they actively call them to mind—when they generate them—than when they simply read them.
  • When you engage actively in a task, you set off intricate mental processes that allow you to retain more knowledge. You learn more and remember more. When you repeat the same task over a long period, your brain constructs specialized neural circuits dedicated to the activit
  • What looks like instinct is hard-won skill, skill that requires exactly the kind of struggle that modern software seeks to alleviate.
  • In many businesses, managers and other professionals have come to depend on decision-support systems to analyze information and suggest courses of action. Accountants, for example, use the systems in corporate audits. The applications speed the work, but some signs suggest that as the software becomes more capable, the accountants become less so.
  • You can put limits on the scope of automation, making sure that people working with computers perform challenging tasks rather than merely observing.
  • Experts used to assume that there were limits to the ability of programmers to automate complicated tasks, particularly those involving sensory perception, pattern recognition, and conceptual knowledge
  • Who needs humans, anyway? That question, in one rhetorical form or another, comes up frequently in discussions of automation. If computers’ abilities are expanding so quickly and if people, by comparison, seem slow, clumsy, and error-prone, why not build immaculately self-contained systems that perform flawlessly without any human oversight or intervention? Why not take the human factor out of the equation?
  • The cure for imperfect automation is total automation.
  • That idea is seductive, but no machine is infallible. Sooner or later, even the most advanced technology will break down, misfire, or, in the case of a computerized system, encounter circumstances that its designers never anticipated. As automation technologies become more complex, relying on interdependencies among algorithms, databases, sensors, and mechanical parts, the potential sources of failure multiply. They also become harder to detect.
  • conundrum of computer automation.
  • Because many system designers assume that human operators are “unreliable and inefficient,” at least when compared with a computer, they strive to give the operators as small a role as possible.
  • People end up functioning as mere monitors, passive watchers of screens. That’s a job that humans, with our notoriously wandering minds, are especially bad at
  • people have trouble maintaining their attention on a stable display of information for more than half an hour. “This means,” Bainbridge observed, “that it is humanly impossible to carry out the basic function of monitoring for unlikely abnormalities.”
  • a person’s skills “deteriorate when they are not used,” even an experienced operator will eventually begin to act like an inexperienced one if restricted to just watching.
  • You can program software to shift control back to human operators at frequent but irregular intervals; knowing that they may need to take command at any moment keeps people engaged, promoting situational awareness and learning.
  • What’s most astonishing, and unsettling, about computer automation is that it’s still in its early stages.
  • most software applications don’t foster learning and engagement. In fact, they have the opposite effect. That’s because taking the steps necessary to promote the development and maintenance of expertise almost always entails a sacrifice of speed and productivity.
  • Learning requires inefficiency. Businesses, which seek to maximize productivity and profit, would rarely accept such a trade-off. Individuals, too, almost always seek efficiency and convenience.
  • Abstract concerns about the fate of human talent can’t compete with the allure of saving time and money.
  • The small island of Igloolik, off the coast of the Melville Peninsula in the Nunavut territory of northern Canada, is a bewildering place in the winter.
  • , Inuit hunters have for some 4,000 years ventured out from their homes on the island and traveled across miles of ice and tundra to search for game. The hunters’ ability to navigate vast stretches of the barren Arctic terrain, where landmarks are few, snow formations are in constant flux, and trails disappear overnight, has amazed explorers and scientists for centuries. The Inuit’s extraordinary way-finding skills are born not of technological prowess—they long eschewed maps and compasses—but of a profound understanding of winds, snowdrift patterns, animal behavior, stars, and tides.
  • The Igloolik hunters have begun to rely on computer-generated maps to get around. Adoption of GPS technology has been particularly strong among younger Inuit, and it’s not hard to understand why.
  • But as GPS devices have proliferated on Igloolik, reports of serious accidents during hunts have spread. A hunter who hasn’t developed way-finding skills can easily become lost, particularly if his GPS receiver fails.
  • The routes so meticulously plotted on satellite maps can also give hunters tunnel vision, leading them onto thin ice or into other hazards a skilled navigator would avoid.
  • An Inuit on a GPS-equipped snowmobile is not so different from a suburban commuter in a GPS-equipped SUV: as he devotes his attention to the instructions coming from the computer, he loses sight of his surroundings. He travels “blindfolded,” as Aporta puts it
  • A unique talent that has distinguished a people for centuries may evaporate in a generation.
  • Computer automation severs the ends from the means. It makes getting what we want easier, but it distances us from the work of knowing. As we transform ourselves into creatures of the screen, we face an existential question: Does our essence still lie in what we know, or are we now content to be defined by what we want?

  • Faith is a concept that often enters the accounts of GPS-induced mishaps. “It kept saying it would navigate us a road,” said a Japanese tourist in Australia who, while attempting to reach North Stradbroke Island, drove into the Pacific Ocean. A man in West Yorkshire, England, who took his BMW off-road and nearly over a cliff, told authorities that his GPS “kept insisting the path was a road.” In perhaps the most infamous incident, a woman in Belgium asked GPS to take her to a destination less than two hours away. Two days later, she turned up in Croatia.
  • These episodes naturally inspire incredulity, if not outright mockery. After a couple of Swedes mistakenly followed their GPS to the city of Carpi (when they meant to visit Capri), an Italian tourism official dryly noted to the BBC that “Capri is an island. They did not even wonder why they didn’t cross any bridge or take any boat.” An Upper West Side blogger’s account of the man who interpreted “turn here” to mean onto a stairway in Riverside Park was headlined “GPS, Brain Fail Driver.”
  • several studies have demonstrated empirically what we already know instinctively. Cornell researchers who analyzed the behavior of drivers using GPS found drivers “detached” from the “environments that surround them.” Their conclusion: “GPS eliminated much of the need to pay attention.”

  • We seem driven (so to speak) to transform cars, conveyances that show us the world, into machines that also see the world for
  • There is evidence that one’s cognitive map can deteriorate. A widely reported study published in 2006 demonstrated that the brains of London taxi drivers have larger than average amounts of gray matter in the area responsible for complex spatial relations. Brain scans of retired taxi drivers suggested that the volume of gray matter in those areas also decreases when that part of the brain is no longer being used as frequently. “I think it’s possible that if you went to someone doing a lot of active navigation, but just relying on GPS,” Hugo Spiers, one of the authors of the taxi study, hypothesized to me, “you’d actually get a reduction in that area.”
  • A consequence is a possible diminution of our “cognitive map,” a term introduced in 1948 by the psychologist Edward Tolman of the University of California, Berkeley. In a groundbreaking paper, Dr. Tolman analyzed several laboratory experiments involving rats and mazes. He argued that rats had the ability to develop not only cognitive “strip maps” — simple conceptions of the spatial relationship between two points — but also more comprehensive cognitive maps that encompassed the entire maze.
  • Could society’s embrace of GPS be eroding our cognitive maps? For Julia Frankenstein, a psychologist at the University of Freiburg’s Center for Cognitive Science, the danger of GPS is that “we are not forced to remember or process the information — as it is permanently ‘at hand,’ we need not think or decide for ourselves.” She has written that we “see the way from A to Z, but we don’t see the landmarks along the way.” In this sense, “developing a cognitive map from this reduced information is a bit like trying to get an entire musical piece from a few notes.” GPS abets a strip-map level of orientation with the world.
  • We seem driven (so to speak) to transform cars, conveyances that show us the world, into machines that also see the world for us.
  • For Dr. Tolman, the cognitive map was a fluid metaphor with myriad applications. He identified with his rats. Like them, a scientist runs the maze, turning strip maps into comprehensive maps — increasingly accurate models of the “great God-given maze which is our human world,” as he put it. The countless examples of “displaced aggression” he saw in that maze — “the poor Southern whites, who take it out on the Negros,” “we psychologists who criticize all other departments,” “Americans who criticize the Russians and the Russians who criticize us” — were all, to some degree, examples of strip-map comprehension, a blinkered view that failed to comprehend the big picture. “What in the name of Heaven and Psychology can we do about it?” he wrote. “My only answer is to preach again the virtues of reason — of, that is, broad cognitive maps.”

  • Boris Johnson plunged the country into harsh new restrictions, blaming a new variant of the disease that had been spreading in London and the southeast of England since September.

  • In the end, 2020 saw a 76% decline in visitors and an 80% drop.
  • "A lot of our multi-country trips including England used to fly round-trip to London, and now we're looking to see if from a traveler's perspective that will be the most convenient."
  • DaSilva said that potential Brexit complications were on the radar of travelers' concerns last year, but, with a no-deal averted and the pandemic taking center stage, it's no longer an issue for her guests. In fact, three of the top five most searched trips on their website involve Great Britain.
  • "Early on in the pandemic, people were searching for places that had more open green spaces, like New Zealand and Ireland," she says. "But as news of the vaccine came out and people became more confident about trips for this year, England popped back up to the top."
  • And there's one big bonus for those traveling to the UK this year --- the tanking pound.
  • The UK made a great play that it was an international and welcoming destination over the 2012 Olympics, but that message was withdrawn with Brexit. The posturing of the government -- especially the threat to put gunboats in the Channel -- didn't play well with a lot of origin markets," he says.
  • "There may be differences with the import of goods and transmission of services that means London isn't as prosperous as it was."
  • "Suddenly, using the UK as gateway to Europe becomes enormously less attractive. Travelers will have to think about whether it's sensible to come to the UK as part of a European destination. They may wish to look at the UK as a single destination, but that isn't nearly as attractive as the UK being part of a European vacation."
  • "The UK won't be ignored, but it's unlikely to recover as strongly as Europe.
  • About 20% of the Intercontinental's staff left the UK before Brexit, says Ouseph; but while in normal times that would be a crisis, he thinks that Covid-induced job losses will mean hotels can fill these positions for now -- at least, the customer-facing ones. Instead, it's the less visible, but crucial roles, where they'll struggle.
  • Not everyone thinks Brexit will make a big difference to the inbound UK travel industry.
  • Maine -- who hasn't run tours since October -- says that he thinks the vaccine "will get us out of it -- it's a matter of when, not if." And he predicts that "when" could be as early as Easter.
  • "Rolling out the vaccine is the acid test of being a coherent holiday destination, and the UK looks like it's doing a reasonably good job in comparison to everyone else."

The Case for Teaching Ignorance - The New York Times - 1 views

TOK knowledge ignorance Kuhn ambiguity psychology science anomalies curiosity

  • Far too often, she believed, teachers fail to emphasize how much about a given topic is unknown.
  • She wanted her students to recognize the limits of knowledge and to appreciate that questions often deserve as much attention as answers
  • in recent years scholars have made a convincing case that focusing on uncertainty can foster latent curiosity, while emphasizing clarity can convey a warped understanding of knowledge.
  • ...12 more annotations...
  • Presenting ignorance as less extensive than it is, knowledge as more solid and more stable, and discovery as neater also leads students to misunderstand the interplay between answers and questions.
  • Discovery is not the neat and linear process many students imagine, but usually involves, in Dr. Firestein’s phrasing, “feeling around in dark rooms, bumping into unidentifiable things, looking for barely perceptible phantoms.”
  • As he argued in his 2012 book “Ignorance: How It Drives Science,” many scientific facts simply aren’t solid and immutable, but are instead destined to be vigorously challenged and revised by successive generations.
  • People tend to think of not knowing as something to be wiped out or overcome, as if ignorance were simply the absence of knowledge. But answers don’t merely resolve questions; they provoke new ones.
  • The larger the island of knowledge grows, the longer the shoreline — where knowledge meets ignorance — extends. The more we know, the more we can ask.
  • Questions don’t give way to answers so much as the two proliferate together. Answers breed questions. Curiosity isn’t merely a static disposition but rather a passion of the mind that is ceaselessly earned and nurtured.
  • Mapping the coast of the island of knowledge, to continue the metaphor, requires a grasp of the psychology of ambiguity. The ever-expanding shoreline, where questions are born of answers, is terrain characterized by vague and conflicting information. The resulting state of uncertainty, psychologists have shown, intensifies our emotions: not only exhilaration and surprise, but also confusion and frustration.
  • The borderland between known and unknown is also where we strive against our preconceptions to acknowledge and investigate anomalous data, a struggle Thomas S. Kuhn described in his 1962 classic, “The Structure of Scientific Revolutions.”
  • giving due emphasis to unknowns, highlighting case studies that illustrate the fertile interplay between questions and answers, and exploring the psychology of ambiguity are essential.
  • The time has come to “view ignorance as ‘regular’ rather than deviant,” the sociologists Matthias Gross and Linsey McGoey have boldly argued. Our students will be more curious — and more intelligently so — if, in addition to facts, they were equipped with theories of ignorance as well as theories of knowledge.
  • This article makes an excellent case for "ignorance studies" but, ironically, treats "agnotology" as a cutting edge concept when in fact it is an old notion with a long history and a better name: "nescience." Nescience can refer to the Socratic idea of learned ignorance, but the concept was also developed in the eighteenth century, chiefly by Scottish commonsense philosopher Thomas Reid
  • "nescience" has considerable advantages over "agnotology". Linguistically, nescience is the precise opposite of "science" (scio: "I know"; nescio: "I don't know"). So why not stick with the Latin root word--and avoid any of the unfortunate connotations "ignorance" has in contemporary parlance? Historically, the word reminds us of the concept's provenance in Socratic philosophy and the Scottish enlightenment. Finally, unearthing the history of "nescience" might yield an unexpected insight into American intellectual history, since many of our founders read Thomas Reid's philosophy in college.

  • There is no conventional “narrative” to Fortnite Battle Royale – Epic doesn’t provide an origin story for its endless 100-player wars, it doesn’t give us long cinematic scenes with characters explaining the world, the factions and the plot. Instead, Fortnite is split into a series of three-month-long seasons, each with a climactic event that suggests some kind of interdimensional struggle taking place over the future of the game’s isolated island locale.
  • Ostensibly, there’s no need for a narrative – Epic could, in theory, retain player interest simply by making sure there is a steady supply of new dance moves, costumes and scenic features to enjoy. Instead, the studio has built a vast functional universe in which an alien known as The Visitor is attempting to mend the space-time fissure around the island, and communicated this through systems of signs, signals and miracles – sort of like the Medieval Christian church
  • Indeed, it’s interesting how Fortnite has co-opted a lot of religious symbolism into the game’s suggestive narrative, from comets trailing across the sky, to the decidedly apocalyptic imagery of fire, brimstone and global destruction.
  • ...5 more annotations...
  • We have seen the rise of massively multiplayer adventures such as World of Warcraft, where global arching narratives are woven into the largely player-directed quests, and we have seen plenty of interesting live story experiments, such as the mostly single-player adventure Dark Souls allowing players to leave messages to each other within the game.
  • For Season 10, Epic was always building toward something vast and catastrophic and upped the narrative signalling accordingly. Throughout the last months players have been able to find audiotapes hidden around the map in which The Visitor has made recordings about his attempts to fix a loop in time and prevent a singularity. It sounds like the ravings of a conspiracy theorist, echoing back the most extreme theories from the fanbase itself
  • Fortnite has been criticised as a shallow, cynical machine of compulsion, its trendy dances and outlandish outfits a means of ensnaring younger players. But as a purveyor of new forms of storytelling, in which the community is left to construct its own narrative based around subtle semiotic systems and climactic events, it is a fascinating innovator.
  • But Fortnite is playing with storytelling concepts, tropes and systems while also providing a piece of blockbuster entertainment for millions of mostly teenage players. It’s like a new Marvel superhero movie being performed entirely in interpretive dance.
  • When Chapter 2 inevitably begins, bringing a new landscape with new gameplay features, it will be interesting to see where Epic goes next on its somewhat transgressive storytelling odyssey. It is, after all, quite hard to top the end of the world as a narrative device.

  • Fox Island Environmental Education Center, a Virginia institution that has opened up the wonders of the natural world to young people for more than 40 years, shut down in November. Between erosion and sea level rise, so much of the island’s salt marsh had disappeared that “it made it unsafe to run the program,” said Tom Ackerman, vice president for education at the Chesapeake Bay Foundation, which owns the island center.
  • because south Louisiana’s land is subsiding while the oceans are rising, the region has what may be the highest relative sea level rise in the country. “We’re just 10 to 30 years in front of the curve of everybody else,” he said.
  • Officials predict that, without action, the lab might need to shut down several dozen days each year within the next 10 to 15 years. The corrosive saltwater attacks the structure and has risen up through the soil into buried electrical cables, at one point causing a blackout. Some floods are accompanied by droves of fiddler crabs that sometimes find their way into the elevators.
  • Many marine labs are preparing to meet similar challenges, though they are in locations that are not yet facing the level of threat that Louisiana is.
  • At the Louisiana center, Ms. Conover sees educational value in their problems. Along with its mission as a scientific research facility, it is also a center for environmental education with visits from some 5,000 students each year. “If our parking lot is flooding when a group is here, we definitely talk about why we’re flooding on that given day, when five years ago we wouldn’t, given the same conditions.” That example, she said, “gives the perspective of what our coastal communities are dealing with.”
  • “Global sea-level rise is one of the greatest challenges facing society in the 21st century, and understanding how this phenomenon impacts coastal systems, infrastructure and the people who use them requires a regular coastal presence.”

Shouting into the apocalypse: The decade in climate change (opinion) - CNN - 0 views

  • What's that worn-out phrase? Shouting into the wind? Well, after a decade of rising pollution, failed politics and worsening disasters, it seems the many, many of us who care about the climate crisis increasingly are shouting into the hurricane, if not the apocalypse.
  • On the cusp of 2020, the state of the planet is far more dire than in 2010. Preserving a safe and healthy ecological system is no longer a realistic possibility. Now, we're looking at less bad options, ceding the fact that the virtual end of coral reefs, the drowning of some island nations, the worsening of already-devastating storms and the displacement of millions -- they seem close to inevitable. The climate crisis is already costly, deadly and deeply unjust, putting the most vulnerable people in the world, often who've done the least to cause this, at terrible risk.
  • There are two numbers you need to understand to put this moment in perspective.The first is 1.5. The Paris Agreement -- the international treaty on climate change, which admittedly is in trouble, but also is the best thing we've got -- sets the goal of limiting warming to 1.5 or, at most, below 2 degrees Celsius of warming.
  • ...6 more annotations...
  • Worldwide fossil fuel emissions are expected to be up 0.6% in 2019 over 2018, according to projections from the Global Carbon Project. In the past decade, humans have put more than 350 metric gigatons of carbon dioxide into the atmosphere from burning fossil fuels and other industrial processes, according to calculations provided by the World Resources Institute.
  • Meanwhile, scientists are becoming even more concerned about tipping points in the climate system that could lead to rapid rise in sea levels, the deterioration of the Amazon and so on. One particularly frightening commentary last month in the journal Nature, by several notable climate scientists, says the odds we can avoid tipping points in the climate system "could already have shrunk towards zero." In non-science-speak: We're there now.
  • This was the decade when some people finally started to see the climate crisis as personal. Climate attribution science, which looks for human fingerprints on extreme weather events, made its way into the popular imagination. We're starting to realize there are no truly "natural" disasters anymore. We've warmed the climate, and we're already making storms riskier.
  • The news media is picking that up, using terms such as "climate emergency" and "climate crisis" instead of the blander "climate change." Increasingly, lots of people are making these critical connections, which should motivate the political, social and economic revolution necessary to fix things.
  • Only 52% of American adults say they are "very" or "extremely" sure global warming is happening, according to a report from the Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication, which is based on a 1,303 person survey conducted in November 2019. Yale's been asking that question for a while now. Go back a decade, to 2009, and the rate is about the same: 51%.
  • The bright spot -- and it truly is a bright one -- is that young people are waking up. They are shouting, loudly and with purpose. Witness Greta Thunberg, the dynamic teenager who started a one-girl protest outside the Swedish Parliament last year, demanding that adults take seriously this emergency, which threatens young people and future generations disproportionately.
