Modern Humans and Neanderthals Coexisted in Europe for at Least 10,000 Years

“One of the infant teeth (a deciduous left upper first molar) whose age had been underestimated. The white bar is 1 centimeter in length.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A4) The fossils seemed hardly worth a second look. The one from England was only a piece of jawbone with three teeth, and the other, from southern Italy, was nothing more than two infant teeth. But scientists went ahead, re-examining them with refined techniques, and found that one specimen’s age had previously been significantly underestimated and that the other’s dating and identity had been misinterpreted.

They had in fact discovered the oldest known skeletal remains of anatomically modern humans in the whole of Europe, two international research teams reported Wednesday.
The scientists who made the discovery and others who study human origins say they expect the findings to reignite debate over the relative capabilities of the immigrant modern humans and the indigenous Neanderthals, their closest hominid relatives; the extent of their interactions; and perhaps the reasons behind the Neanderthal extinction. The findings have already prompted speculation that the Homo sapiens migrations into Europe may have come in at least two separate waves, rather than just one.
In tests conducted at the Oxford Radiocarbon Accelerator Unit in England, the baby teeth from Italy were dated at 43,000 to 45,000 years old. Other analysis showed the teeth to be those of a modern human, not a Neanderthal, as previously thought when the fossil was unearthed in 1964 from the Grotta del Cavallo.

The Huge Value of Exposing Ourselves to Unexpected Evidence

Bill Bryson tells how much we learned from the remains of a man from the neolithic age, who has been called Ötzi:

(p. 377) His equipment employed eighteen different types of wood – a remarkable variety. The most surprising of all his tools was the axe. It was copper-bladed and of a type known as a Remedello axe, after a site in Italy where they were first found. But Ötzi’s axe was hundreds of years older than the oldest Remedello axe. ‘It was,’ in the words of one observer, ‘as if the tomb of a medieval warrior had yielded a modern rifle.’ The axe changed the timeframe for the copper age in Europe by no less than a thousand years.

But the real revelation and excitement were the clothes. Before Ötzi we had no idea – or, to be more precise, nothing but ideas – of how stone age people dressed. Such materials as survived existed only as fragments. Here was a complete outfit and it was full of surprises. His clothes were made from the skins and furs of an impressive range of animals – red deer, bear, chamois, goat and cattle. He also had with him a woven grass rectangle that was three feet long. This might have been a kind of rain cape, but it might equally have been a sleeping mat. Again, nothing like it had ever been seen or imagined.
Ötzi wore fur leggings held up with leather strips attached to a waist strap that made them look uncannily – almost comically – like the kind of nylon stockings and garter sets that Hollywood pin-ups wore in the Second World War. Nobody had remotely foreseen such a get-up. He wore a loincloth of goatskin and a hat made from the fur of a brown bear – probably a kind of hunting trophy. It would have been very warm and covetably stylish. The rest of his outfit was mostly made from the skin and fur of red deer. Hardly any came from domesticated animals, the opposite of what was expected.

Easter Island Was Ravaged by Rats, Peruvian Slaving Parties and Nonnative Diseases, Not by Ecocide

Source of book image: http://0.tqn.com/d/archaeology/1/0/g/L/1/Statues-That-Walked-sm.jpg

The natives call Easter Island “Rapa Nui.”

(p. C5) With the forest gone, Rapa Nui’s soil degraded; unable to feed themselves, Mr. Diamond argued in his best-selling “Collapse” (2005), Easter Islanders faced “starvation, a population crash, and a descent into cannibalism.” The fall was abrupt and overwhelming; scores of giant statues were abandoned, half-finished. Roggeveen had discovered a ruin–and a powerful eco-parable.

Books and articles by the hundred have pointed to Rapa Nui as the inevitable result of uncontrolled population growth, squandered resources and human fecklessness. “The person who felled the last tree could see it was the last tree,” wrote Paul G. Bahn and John Flenley in “Easter Island, Earth Island” (1992). “But he (or she) still felled it.” “The parallels between Easter Island and the whole modern world are chillingly obvious,” Mr. Diamond proclaimed. “The clearest example of a society that destroyed itself by overexploiting its own resources,” he said, Rapa Nui epitomizes “ecocide,” presenting a stark image of “what may lie ahead of us in our own future.”
No, it doesn’t, write archaeologists Terry Hunt and Carl Lipo in “The Statues That Walked,” a fascinating entry in the pop-science genre of Everything You Know Is Wrong. Messrs. Hunt and Lipo had no intention of challenging Mr. Diamond when they began research on Rapa Nui. But in their fourth year of field work, they obtained radiocarbon dates from Anakena Beach, thought to be the island’s oldest settlement. The dates strongly indicated that the first settlers appeared around A.D. 1200–eight centuries later than Heyerdahl and other researchers had thought.
Wait a minute, the authors in effect said. Rapa Nui is so remote that researchers believe it must have been settled by a small group of adventurers–a few dozen people, brave or crazy, in boats. The new evidence suggested that their arrival had precipitated catastrophic deforestation “on the scale of decades, not centuries.” The island then probably had only a few hundred inhabitants. Some ecologists estimate that the island originally had 16 million palm trees. How could so few people have cut down so much so fast?
. . .
The real culprit, according to “The Statues That Walked,” was the Polynesian rat (Rattus exulans), which stowed away on the boats of the first Polynesian settlers. In laboratory settings, Polynesian rat populations can double in 47 days. Throw a breeding pair into an island with no predators and abundant food and arithmetic suggests the result: ratpocalypse. If the animals multiplied as they did in Hawaii, the authors calculate, Rapa Nui would quickly have housed between two and three million. Among the favorite food sources of R. exulans are tree seeds and tree sprouts. Humans surely cleared some of the forest, but the real damage would have come from the rats that prevented new growth.
“Rather than a case of abject failure,” the authors argue, “Rapa Nui is an unlikely story of success.” The islanders had migrated, perhaps accidentally, to a place with little water and “fundamentally unproductive” soil with “uniformly low” levels of phosphorus, an essential mineral for plant growth. To avoid the wind’s dehydrating effects, the newcomers circled their gardens with stone walls known as manavai. Today, the researchers discovered, abandoned manavai occupy about 6.4 square miles, a tenth of the island’s total surface.
More impressive still, about half of the island is covered by “lithic mulching,” in which the islanders scattered broken stone over the fields. The uneven (p. C6) surface creates more turbulent airflow, reducing daytime surface temperatures and warming fields at night. And shattering the rocks exposes “fresh, unweathered surfaces, thus releasing mineral nutrients held within the rock.” Only lithic mulching produced enough nutrients–just barely–to make Rapa Nui’s terrible soil cultivable. Breaking and moving vast amounts of stone, the islanders had engineered an entirely new, more productive landscape.
Their success was short-lived. As Messrs. Hunt and Lipo point out, the 18th and 19th centuries were terrible times to reside in a small, almost defenseless Pacific nation. Rapa Nui was repeatedly ravaged by Peruvian slaving parties and nonnative diseases.
. . .
Easter Island’s people did not destroy themselves, the authors say. They were destroyed.
. . .
Oral tradition said that the statues walked into their places. Oral tradition was correct, the authors say. By shaping the huge statues just right, the islanders were able to rock them from side to side, moving them forward in a style familiar to anyone who has had to move a refrigerator. Walking the statues, the authors show in experiments, needed only 15 or 20 people.
In a 2007 article in Science, Mr. Diamond estimated that hundreds of laborers were needed to move the statues, suggesting that the eastern settlements of the island alone had to have “a population of thousands”–which in turn was proof of the island’s destructive overpopulation. By showing that the statues could have been moved by much fewer people, Messrs. Hunt and Lipo have removed one of the main supports of the ecocide theory and the parable about humankind it tells.

Warm Yourself Over a “Dung Fire, and You Will Know What Pollution Really Is”

(p. D4) To the Editor:
The idea that ancient man had fewer tumors because he lived in a less polluted atmosphere (“Unearthing Prehistoric Tumors, and Debate,” Dec. 28) can be held only by those who have limited experience living in a preindustrial way. Try cooking over an open fire burning half-rotten wood, or sitting in a cave warming yourself with a peat or dung fire, and you will know what pollution really is.

Partage Provides Incentives to Recover Antiquities and the Means to Preserve Them

Source of book image: http://press.princeton.edu/images/k8602.gif

(p. D1) In some cases, it makes aesthetic or archaeological sense to keep artifacts grouped together where they were found, but it can also be risky to leave everything in one place, particularly if the country is in turmoil or can’t afford to excavate or guard all its treasures. After the Metropolitan Museum was pressured to hand over a collection called the Lydian Hoard, one of the most valuable (p. D2) pieces was stolen several years ago from its new home in Turkey.
. . .
(p. D2) In his book “Who Owns Antiquity?”, James Cuno argues that scholars have betrayed their principles by acquiescing to politicians who have exploited antiquities to legitimize themselves and their governments. Saddam Hussein was the most blatant, turning Iraqi archeology museums into propaganda for himself as the modern Nebuchadnezzar, but other leaders have been just as cynical in using antiquities to bolster their claims of sovereignty.

Dr. Cuno advocates the revival of partage, the traditional system in which archeologists digging in foreign countries would give some of their discoveries to the host country and take others home. That way both sides benefit, and both sides have incentives to recover antiquities before looters beat them to it. . . .
As the director of the Art Institute of Chicago, Dr. Cuno has his own obvious motives for acquiring foreign antiquities, and he makes no apology for wanting to display Middle Eastern statues to Midwesterners.
“It is in the nature of our species to connect and exchange,” Dr. Cuno writes. “And the result is a common culture in which we all have a stake. It is not, and can never be, the property of one modern nation or another.”
Some of the most culturally protectionist nations today, like Egypt, Italy and Turkey, are trying to hoard treasures that couldn’t have been created without the inspiration provided by imported works of art. (Imagine the Renaissance without the influence of “looted” Greek antiquities.) And the current political rulers of those countries often have little in common culturally with the creators of the artifacts they claim to own.

Neanderthals and Cro-Magnons Did Not Much Overlap: Evidence Against an Early Human Golden Age

In 2010 archeologist Brian Fagan published a book that used his read of the evidence to imagine the interactions between Cro-Magnon (us) and Neanderthal humans. He mostly portrayed the interaction as one of wary, but mainly benign mutual neglect. His broader portrayal of the lives of the hunter-gatherer Cro-Magnons did not completely place them in a Golden Age, but did much to praise many aspects of their lives.
Also in 2010, Matt Ridley published a book that discussed and dismissed the view that the hunter-gatherers were to be admired. He mainly pointed to the evidence of how common violent death was among hunter-gatherers, and hence how precarious and fearful their lives must have been.
Now there is additional relevant evidence. Apparently the period of overlap between Cro-Magnons and Neanderthals was much briefer than had been previously believed. This implies (see below) that rather than benign mutual neglect, it is much more likely that the Cro-Magnons violently wiped out the Neanderthals.
Hobbes may not have been entirely wrong when he described early human life as “nasty, poor, brutish and short.”

(p. D4) An improvement in the dating of fossils suggests that the Neanderthals, a heavily muscled, thick-boned human species adapted to living in ice age Europe, perished almost immediately on contact with the modern humans who started to enter Europe from the Near East about 44,000 years ago. Until now bones from several Neanderthal sites have been dated to as young as 29,000 years ago, suggesting there was extensive overlap between the two human species. This raised the question of whether there had been interbreeding between humans and Neanderthals, an issue that is still not resolved.
. . .
Reviewing . . . Neanderthal dates ascertained with the new ultrafiltration method, Dr. Higham sees an emerging pattern that no European Neanderthal site can reliably be dated to less than 39,000 years ago. “It’s only with reliable techniques that we can interpret the archaeological past,” he said.
He is re-dating Neanderthal sites across Europe and so far sees no evidence for any extensive overlap between Neanderthals and modern humans. “There was a degree of contemporaneity, but it may not have been very long,” he said. A short period of contact would point to the extinction of the Neanderthals at the hands of modern humans.
“It’s very unlikely for Neanderthals to go extinct without some agency from modern humans,” Dr. Higham said.
Paul Mellars, an expert on Neanderthals at Cambridge University in England, said that the quality of the dates from Dr. Higham’s laboratory was superb and that samples of bone re-dated by the lab’s method were almost always found to be several thousand years older than previously measured. The picture supported by the new dates is that the interaction between modern humans and Neanderthals in Europe was brief in each region, lasting perhaps a few hundred years, Dr. Mellars said, until the modern humans overwhelmed their competitors through better technology and greater numbers.

45% of Mummies Had Heart Disease

“A mummy enters the CT scanner at St. Luke’s Hospital in Kansas City, Mo. It was one of 52 mummies examined for signs of heart disease.” Source of caption and photo: online version of the Omaha World-Herald article quoted and cited below.

(p. 6A) Atherosclerosis — hardening of the arteries — was surprisingly widespread during ancient times, at least among the Egyptian mummies examined by an international team of scientists and heart specialists.

Their research, whose results were presented April 3 in New Orleans at the annual meeting of the American College of Cardiology, found that 45 percent of the mummies they put through CT scans had signs of atherosclerosis.
That raises questions about whether hardening of the arteries is the modern disease that many think it is.
“We found it so easily and frequently that it appears to have been common in this society,” said Randall Thompson, a cardiologist at St. Luke’s Hospital in Kansas City.

Middle-Class Today Live Better than 99.4% of Humans Who Ever Lived

(p. 80) In his extraordinary book Mapping Human History, the science writer Steve Olson estimates that 80 billion “modern” humans–from the first beings recognizable as our forebears to the advent of Homo sapiens sapiens, our official name–have walked the earth down through the millennia. Supposing this number is correct, the men and women at middle-class standards or above in the United States and the European Union now live better than 99.4 percent of the human beings who have ever existed.

The “Golden Age” When Enemy Blood Was Sipped from Skull-Cups

“Skull-cups found in Somerset, England, were worked with flint tools 14,700 years ago.” Source of caption and photo: online version of the NYT article quoted and cited below.

If you are one of those who longs nostalgically for the “Golden Age” of our hunter-gatherer paleolithic past, read on:

(p. D3) The three human braincases, two from adults and one from a child, were carefully skinned and cleaned with flint tools. The soft tissue was removed and probably consumed, leaving a well-shaped cup, perhaps made for use in some sort of ritual.

This is not a scene from a horror film. British paleoanthropologists report the discovery of these 14,700-year-old skull-cups in the journal PLoS One. They were found in Gough’s Cave in Somerset, England, and are the oldest directly dated skull-cups known, based on radiocarbon analysis.
. . .
Historical accounts hold that other human societies, like the Scythians, nomadic Indo-European warriors, used skull-cups to sip the blood of enemies. And as late as the 19th century, skull-cups were reportedly used in Fiji and other islands in Oceania.

First Writing Grew from Commerce

“A Sumerian clay tablet from around 3200 B.C. is inscribed in wedgelike cuneiform with a list of professions.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. C5) CHICAGO — One of the stars of the Oriental Institute’s new show, “Visible Language: Inventions of Writing in the Ancient Middle East and Beyond,” is a clay tablet that dates from around 3200 B.C. On it, written in cuneiform, the script language of ancient Sumer in Mesopotamia, is a list of professions, described in small, repetitive impressed characters that look more like wedge-shape footprints than what we recognize as writing.
In fact “it is among the earliest examples of writings that we know of so far,” according to the institute’s director, Gil J. Stein, and it provides insights into the life of one of the world’s oldest cultures.
The new exhibition by the institute, part of the University of Chicago, is the first in the United States in 26 years to focus on comparative writing. It relies on advances in archaeologists’ knowledge to shed new light on the invention of scripted language and its subsequent evolution.
The show demonstrates that, contrary to the long-held belief that writing spread from east to west, Sumerian cuneiform and its derivatives and Egyptian hieroglyphics evolved separately from each another. And those writing systems were but two of the ancient forms of writing that evolved independently. Over a span of two millenniums, two other powerful civilizations — the Chinese and Mayans — also identified and met a need for written communication. Writing came to China as early as around 1200 B.C. and to the Maya in Mesoamerica long before A.D. 500.
. . .
The Oriental Institute, which opened in 1919, was heavily financed by John D. Rockefeller Jr., who had been greatly influenced by James Henry Breasted, a passionate archaeologist.
. . .
Experts are still struggling to understand just how writing evolved, but one theory, laid out at the Oriental Institute’s exhibition, places the final prewriting stage at 3400 B.C., when the Sumerians first began using small clay envelopes like the ones in the show. Some of the envelopes had tiny clay balls sealed within. Archaeologists theorize that they were sent along with goods being delivered; recipients would open them and ensure that the number of receivables matched the number of clay tokens. The tokens, examples of which are also are in the show , transmitted information, a key function of writing.
