What is an individual in nature?
Derek J Skillings writes: When she was two years old, I took my daughter to the American Museum of Natural History for the first time. As we strolled through the displays of taxidermy animals, she would waddle towards each one, and point and ask what we were looking at. When we entered the Hall of African Mammals, she was so overwhelmed by the presence of her storybook companions that she could only manage to jump up and down on the spot while shouting a mishmash of half-formed names. Leophant! Zeepotamus! Seeing her favourite animals was the highlight of her day, but mine was reliving the excitement of discovering strange new beings, as my daughter asked, wide-eyed, over and over again: what’s that?
Most of the time the living world appears to us as manageable chunks. Even a toddler can see that. We know if we have one dog or two; at a pinch, we can probably count how many trees are growing in our backyard. Natural history museums started, in part, as embodiments of early scientific approaches to ordering and cataloguing the diversity of life. This is possible only because humans can usually intuitively pick out one organism from the next – that is, because most of the creatures we come across have pretty clear boundaries in space and time. When my daughter and I stood back and considered a herd of frozen elephants walking in a line at the museum, it was clear – even for a baby with its trunk wrapped tenderly around its mother’s – where one elephant ended and another began.
How come, then, the meaning of individuality is one of the oldest and most vexing problems in biology? For millennia, naturalists and philosophers have struggled to define the most fundamental units of living systems and to delimit the precise boundaries of the organisms that inhabit our planet. This difficulty is partly a product of the search for a singular theory that can be used to carve up all of the living world at its joints. But my view is that no such unified theory exists; there’s no single answer to the question: ‘What parts of the world are a part of you as a biological individual, and what parts are not?’ Different accounts of individuality pick out different boundaries, like an overlapping Venn diagram drawn on top of a network of biotic interactions. This isn’t because of uncertainty or a lack of information; rather, the living world just exists in such a way that we need more than one account of individuality to understand it.
When you stop to think about it, the problem of individuality is (ironically enough) actually composed of two problems: identity and individuation. The problem of identity asks: ‘What does it mean for a thing to remain the same thing if it changes over time?’ or ‘What makes two entities the same kind of thing?’ The problem of individuation asks: ‘How do we tell things apart?’ or ‘What are the boundaries of an object?’ Identity is fundamentally about the nature of sameness and continuity; individuation is about differences and breaks.

Volcanic eruptions in Alaska could have impacted lives of ancient Egyptians
The Washington Post reports: Did volcanoes in Russia, Greenland and Alaska affect the lives of ancient Egyptians?
It may sound improbable, but according to a new study, the answer is yes.
In a paper published in Nature Communications, a team of researchers shows that volcanic eruptions in high northern latitudes of the globe can affect the Nile watershed, causing the flow of one of the world’s mightiest rivers to slow.
This, in turn, could keep the lower Nile from flooding in the late summer months — a regular occurrence on which ancient Egyptians relied to irrigate their crops.
No Nile flooding meant no irrigation, which meant a bad year in the fields, low food supplies and, ultimately, civic unrest, researchers say.
“It’s a bizarre concept that Alaskan volcanoes were screwing up the Nile, but in fact that’s what happened,” said Joseph Manning, a historian at Yale University who worked on the study. [Continue reading…]

Scientists battle over whether violence has declined over time
Bruce Bower writes: Contrary to a popular idea among researchers, modern states haven’t dulled people’s long-standing taste for killing each other in battle, a controversial new study concludes. But living in a heavily populated society may up one’s odds of surviving a war, two anthropologists propose.
As a population grows, larger numbers of combatants die in wars, but those slain represent a smaller average percentage of the total population, say Dean Falk of Florida State University in Tallahassee and Charles Hildebolt of Washington University School of Medicine in St. Louis. That pattern holds for both small-scale and state societies, the researchers report online October 13 in Current Anthropology.
Increasing absolute numbers of war dead in human societies have resulted from the invention of ever-more-lethal weapons, from stone axes to airborne bombers, the researchers suspect. But Falk and Hildebolt show that states, which centralize political power in a bureaucratic government, are less likely to lose large portions of their populations to war than are small-scale societies, such as hunter-gatherers. That’s a consequence of large populations acting as a buffer against war casualties among noncombatants, not a lesser appetite for violence, the researchers contend.
“Small-scale societies are not more violent than states,” Falk says. “But there is safety in numbers.” [Continue reading…]

A giant insect ecosystem is collapsing due to humans. It’s a catastrophe
Michael McCarthy writes: Thirty-five years ago an American biologist Terry Erwin conducted an experiment to count insect species. Using an insecticide “fog”, he managed to extract all the small living things in the canopies of 19 individuals of one species of tropical tree, Luehea seemannii, in the rainforest of Panama. He recorded about 1,200 separate species, nearly all of them coleoptera (beetles) and many new to science; and he estimated that 163 of these would be found on Luehea seemannii only.
He calculated that as there are about 50,000 species of tropical tree, if that figure of 163 was typical for all the other trees, there would be more than eight million species, just of beetles, in the tropical rainforest canopy; and as beetles make up about 40% of all the arthropods, the grouping that contains the insects and the other creepy-crawlies from spiders to millipedes, the total number of such species in the canopy might be 20 million; and as he estimated the canopy fauna to be separate from, and twice as rich as, the forest floor, for the tropical forest as a whole the number of species might be 30 million.
Yes, 30 million. It was one of those extraordinary calculations, like Edwin Hubble’s of the true size of the universe, which sometimes stop us in our tracks.
Erwin reported that he was shocked by his conclusions and entomologists have argued over them ever since. But about insects, his findings make two things indisputably clear. One is that there are many, many more types than the million or so hitherto described by science, and probably many more than the 10m species sometimes postulated as an uppermost figure; and the second is that this is far and away the most successful group of creatures the Earth has ever seen.
They are multitudinous almost beyond our imagining. They thrive in soil, water, and air; they have triumphed for hundreds of millions of years in every continent bar Antarctica, in every habitat but the ocean. And it is their success – staggering, unparalleled and seemingly endless – which makes all the more alarming the great truth now dawning upon us: insects as a group are in terrible trouble and the remorselessly expanding human enterprise has become too much, even for them.
Does it matter? Oh yes. Most of our fruit crops are insect-pollinated, as are the vast majority of our wild plants
The astonishing report highlighted in the Guardian, that the biomass of flying insects in Germany has dropped by three quarters since 1989, threatening an “ecological Armageddon”, is the starkest warning yet; but it is only the latest in a series of studies which in the last five years have finally brought to public attention the real scale of the problem.

The struggle to protect a tree at the heart of Hopi culture
By Stewart B. Koyiyumptewa and Chip Colwell
A rumbling, low boom unfurled over the land like a current of thunder. But it was a clear, cloudless day in northern Arizona. We realized the reverberation was the echo of an explosion—dynamite loosening the earth—and that the strip mine was finding its way toward a colossal seam of coal.
It was the fall of 2015, and the Kayenta Mine’s owners, Peabody Energy, the world’s largest coal company, had proposed to expand the mine into neighboring areas. If that were to happen, then the place we were standing on would one day be peeled open like a can of sardines to reveal the prize of shiny, midnight-black coal.
The Kayenta Mine has long been a source of controversy. Every year it ships millions of tons of coal by rail to the Navajo Generating Station northeast of the Grand Canyon. The power plant keeps air conditioners humming in Phoenix and Los Angeles, and lights shimmering in Las Vegas and beyond.
We were there as anthropologists with a team of researchers and Hopi elders to study the project’s potential impact on religious sites, archaeological remains, springs, and more. But at every stop, the elders talked about the juniper tree. The trees were so abundant—blanketing every hill that hasn’t been mined—that at first it seemed strange to be concerned about the potential loss of this plant. There were ancient Pueblo villages and graveyards to worry about. There were precious springs and rare songbirds.
But the elders kept returning to their fears for the junipers.

Neutron star collision showers the universe with a wealth of discoveries
Science News reports: Two ultradense cores of dead stars have produced a long-awaited cosmic collision, showering scientists with riches.
The event was the first direct sighting of a smashup of neutron stars, which are formed when aging stars explode and leave behind a neutron-rich remnant. In the wake of the collision, the churning residue forged gold, silver, platinum and a smattering of other heavy elements such as uranium, researchers reported October 16 at a news conference in Washington, D.C. Such elements’ birthplaces were previously unknown, but their origins were revealed by the cataclysm’s afterglow.
“It really is the last missing piece” of the periodic table, says Anna Frebel, an astronomer at MIT who was not involved in the research. “This is heaven for anyone working in the field.” After the collision, about 10 times the Earth’s mass in gold was spewed out into space, some scientists calculated.
Using data gathered by about 70 different observatories, astronomers characterized the event in exquisite detail, releasing a slew of papers describing the results. A tremor of gravitational waves, spotted by the Advanced Laser Interferometer Gravitational-Wave Observatory, LIGO, on August 17, provided the first sign of the cataclysm. [Continue reading…]

How Stalin — and the foreign press corps — hid Ukraine’s famine from the world
Anne Applebaum writes: In the years 1932 and 1933, a catastrophic famine swept across the Soviet Union. It began in the chaos of collectivization, when millions of peasants were forced off their land and made to join state farms. It was then exacerbated, in the autumn of 1932, when the Soviet Politburo, the elite leadership of the Soviet Communist Party, took a series of decisions that deepened the famine in the Ukrainian countryside. Despite the shortages, the state demanded not just grain, but all available food. At the height of the crisis, organized teams of policemen and local Party activists, motivated by hunger, fear, and a decade of hateful propaganda, entered peasant households and took everything edible: potatoes, beets, squash, beans, peas, and farm animals. At the same time, a cordon was drawn around the Ukrainian republic to prevent escape. The result was a catastrophe: At least 5 million people perished of hunger all across the Soviet Union. Among them were nearly 4 million Ukrainians who died not because of neglect or crop failure, but because they had been deliberately deprived of food.
Neither the Ukrainian famine nor the broader Soviet famine were ever officially recognized by the USSR. Inside the country the famine was never mentioned. All discussion was actively repressed; statistics were altered to hide it. The terror was so overwhelming that the silence was complete. Outside the country, however, the cover-up required different, subtler tactics. These are beautifully illustrated by the parallel stories of Walter Duranty and Gareth Jones.
In the 1930s, all of the members of the Moscow press corps led a precarious existence. At the time, they needed the state’s permission to live in the USSR, and even to work. Without a signature and the official stamp of the press department, the central telegraph office would not send their dispatches abroad. To win that permission, journalists regularly bargained with foreign ministry censors over which words they could use, and they kept on good terms with Konstantin Umansky, the Soviet official responsible for the foreign press corps. William Henry Chamberlin, then the Moscow correspondent for the Christian Science Monitor, wrote that the foreign reporter “works under a Sword of Damocles—the threat of expulsion from the country or of the refusal of permission to re-enter it, which of course amounts to the same thing.”
Extra rewards were available to those, like Walter Duranty, who played the game particularly well. Duranty was The New York Times correspondent in Moscow from 1922 until 1936, a role that, for a time, made him relatively rich and famous. British by birth, Duranty had no ties to the ideological left, adopting rather the position of a hard-headed and skeptical “realist,” trying to listen to both sides of the story. “It may be objected that the vivisection of living animals is a sad and dreadful thing, and it is true that the lot of kulaks and others who have opposed the Soviet experiment is not a happy one,” he wrote in 1935—the kulaks being the so-called wealthy peasants whom Stalin accused of causing the famine. But “in both cases, the suffering inflicted is done with a noble purpose.”
This position made Duranty enormously useful to the regime, which went out of its way to ensure that Duranty lived well in Moscow. He had a large flat, kept a car and a mistress, had the best access of any correspondent, and twice received coveted interviews with Stalin. But the attention he won from his reporting back in the U.S. seems to have been his primary motivation. His missives from Moscow made him one of the most influential journalists of his time. In 1932, his series of articles on the successes of collectivization and the Five Year Plan won him the Pulitzer Prize. Soon afterward, Franklin Roosevelt, then the governor of New York, invited Duranty to the governor’s mansion in Albany, where the Democratic presidential candidate peppered him with queries. “I asked all the questions this time. It was fascinating,” Roosevelt told another reporter.
As the famine worsened, Duranty, like his colleagues, would have been in no doubt about the regime’s desire to repress it. In 1933, the Foreign Ministry began requiring correspondents to submit a proposed itinerary before any journey into the provinces; all requests to visit Ukraine were refused. The censors also began to monitor dispatches. Some phrases were allowed: “acute food shortage,” “food stringency,” “food deficit,” “diseases due to malnutrition,” but nothing else. In late 1932, Soviet officials even visited Duranty at home, making him nervous.
In that atmosphere, few of them were inclined to write about the famine, although all of them knew about it. “Officially, there was no famine,” wrote Chamberlin. But “to anyone who lived in Russia in 1933 and who kept his eyes and ears open, the historicity of the famine is simply not in question.” Duranty himself discussed the famine with William Strang, a diplomat at the British embassy, in late 1932. Strang reported back drily that the New York Times correspondent had been “waking to the truth for some time,” although he had not “let the great American public into the secret.” Duranty also told Strang that he reckoned “it quite possible that as many as 10 million people may have died directly or indirectly from lack of food,” though that number never appeared in any of his reporting. Duranty’s reluctance to write about famine may have been particularly acute: The story cast doubt on his previous, positive (and prize-winning) reporting. [Continue reading…]
