OLDEST HUMAN TEETH FOUND: Archaeologists found evidence that humans lived in Israel 400,000 years ago, including these teeth, some of which are dated from 300,000 to 400,000 years ago.

Archaeologists have found evidence of modern humans, Homo sapiens, living in Israel 400,000 years ago. The remains found are the oldest known of the species.

The discovery was made in Qesem Cave near Rosh Ha’ayin in central Israel, which has been excavated by Drs. Avi Gopher and Ran Barkai of Tel Aviv University since 2000.

Researchers from Israel, the United States, and Spain analyzed the shape of eight teeth recovered from Qesem Cave. Using CT scans and X-rays, they found that the teeth are very similar to the teeth of today’s people.

The researchers think that the site was occupied from 420,000 years ago to 200,000 years ago, and five of the eight teeth examined were dated to at least 300,000 years ago.

They also found evidence that the humans who occupied the site used fire regularly and had a systematic way of producing flint blades.

The results were published in the American Journal of Physical Anthropology.

It was previously widely believed that Homo sapiens came into being 200,000 years ago in Africa. According to the researchers, their discovery, together with finds from China and Spain, could overturn the theory that modern humans started life on the African continent.

Chinese Arrogance or Indifference to Truth

There is more to this story - the ramifications of the facts are more than disturbing to the Chinese, they undermine virtually all of Chinese history and mythology, which in turn undermines the authority of the regime in Beijing.




Mystery of the mummy's Chinese travel ban

For her advanced years, she looks remarkable. Despite nearing the ripe old age of 4,000, long eyelashes still frame her half-open eyes and hair tumbles down to her remarkably well-preserved shoulders.

But the opportunity for new audiences in the United States to view the "Beauty of Xiaohe" – a near perfectly preserved mummy from an inhospitable part of western China – has been dealt a blow after it was pulled from an exhibition following a sudden call from the Chinese authorities on the eve of opening. The reason for pulling the mummy and other artefacts from the show remained unclear yesterday (Chinese officials were on New Year holiday) but there were suggestions that the realities of modern Chinese politics may have had a part to play.

The mummy was recovered from China's Tarim Basin, in Xinjiang province. But her Caucasian features raised the prospect that the region's inhabitants were European settlers.

It raises the question about who first settled in Xinjiang and for how long the oil-rich region has been part of China. The questions are important – most notably for the Chinese authorities who face an intermittent separatist movement of nationalist Uighurs, a Turkic-speaking Muslim people who number nine million in Xinjiang.

The government-approved story of China's first contact with the West dates back to 200BC when China's emperor Wu Di wanted to establish an alliance with the West against the marauding Huns, then based in Mongolia. However, the discovery of the mummies suggests that Caucasians were settled in a part of China thousands of years before Wu Di: the notion that they arrived in Xinjiang before the first East Asians is truly explosive.

Xinjiang is dominated by the Uighurs, who resent what they see as intrusion by the Han Chinese. The tensions which have spilled over into violent clashes in recent years.

Whatever the reason for the Chinese decision, it has caused great disappointment at the Pennsylvania museum where the "Secrets of the Silk Road" were due to go on show after successful exhibitions in California and Texas without major reproductions.

"It's going to be the rebirth of this museum," Victor Mair, a professor of Chinese language and literature, told the Associated Press last month. "It's going to put it back on the map."

Ancient Human Remains: Pushes dates around

Researchers: Ancient human remains found in Israel

JERUSALEM –

Israeli archaeologists said Monday they may have found the earliest evidence yet for the existence of modern man, and if so, it could upset theories of the origin of humans.

A Tel Aviv University team excavating a cave in central Israel said teeth found in the cave are about 400,000 years old and resemble those of other remains of modern man, known scientifically as Homo sapiens, found in Israel. The earliest Homo sapiens remains found until now are half as old.

"It's very exciting to come to this conclusion," said archaeologist Avi Gopher, whose team examined the teeth with X-rays and CT scans and dated them according to the layers of earth where they were found.

He stressed that further research is needed to solidify the claim. If it does, he says, "this changes the whole picture of evolution."

The accepted scientific theory is that Homo sapiens originated in Africa and migrated out of the continent. Gopher said if the remains are definitively linked to modern human's ancestors, it could mean that modern man in fact originated in what is now Israel.

Sir Paul Mellars, a prehistory expert at Cambridge University, said the study is reputable, and the find is "important" because remains from that critical time period are scarce, but it is premature to say the remains are human.

"Based on the evidence they've cited, it's a very tenuous and frankly rather remote possibility," Mellars said. He said the remains are more likely related to modern man's ancient relatives, the Neanderthals.

According to today's accepted scientific theories, modern humans and Neanderthals stemmed from a common ancestor who lived in Africa about 700,000 years ago. One group of descendants migrated to Europe and developed into Neanderthals, later becoming extinct. Another group stayed in Africa and evolved into Homo sapiens — modern humans.

Teeth are often unreliable indicators of origin, and analyses of skull remains would more definitively identify the species found in the Israeli cave, Mellars said.

Gopher, the Israeli archaeologist, said he is confident his team will find skulls and bones as they continue their dig.

The prehistoric Qesem cave was discovered in 2000, and excavations began in 2004. Researchers Gopher, Ran Barkai and Israel Hershkowitz published their study in the American Journal of Physical Anthropology.

The Hobbit (for reals)

Studies say 'hobbit' previously unknown species

by Marlowe Hood Marlowe Hood – Thu May 7, 2009

PARIS (AFP) – The tiny ancient humans dubbed hobbits, whose remains were discovered on an Indonesian island in 2003, were a previously unknown species altogether, according to two new studies.

Debate has raged in the scientific community since the fossils were found on the island of Flores, with some experts insisting they were descended from Homo erectus and others saying evolution could not account for their small brains.

About a metre (three feet) tall and weighing 30 kilos (65 pounds), the tiny, tool-making hunters may have roamed the remote island as recently as 8,000 years ago. Their fossils are about 18,000 years old.

Many scientists have said Homo floresiensis, as the creature is now formally known, was a prehistoric human stunted by natural selection over millennia through a process called insular dwarfing.

Others countered that even this evolutionary shrinking, well documented in island-bound animals, could not account for the chimpanzee-sized brain -- just a third the size of that in a modern human being.

The only plausible explanation, they insisted, was that the handful of specimens found had a genetic disorder resulting in an abnormally small skull or that they suffered from "dwarf cretinism" caused by deficient thyroids.

Two new studies in the British journal Nature go a long way toward settling the debate.
A team led by William Jungers of Stony Brook University in New York tackled the problem by analysing the hobbit's foot.

In some ways it is very human. The big toe is aligned with the others and the joints make it possible to extend the toes as the body's full weight falls on the foot -- attributes not found in great apes.

But in other respects it is startlingly primitive: far longer than its modern human equivalent and equipped with a very small big toe, long and curved lateral toes, and a weight-bearing structure closer to a chimpanzee's.

Recent archaeological evidence from Kenya shows that the modern foot evolved more than 1.5 million years ago, most likely in Homo erectus.

So unless the Flores hobbits became more primitive over time -- considered extremely unlikely -- they must have branched off the human line at an even earlier date.

For Jungers and colleagues, this suggests their ancestor was not Homo erectus "but instead some other more primitive hominin whose dispersal into southeast Asia is still undocumented."
Companion studies published by the Journal of Human Evolution bolster this theory and conjecture that these more ancient forebears may be the still poorly understood Homo habilis.
In any case, Homo floresiensis would be confirmed as a separate species.

But what still has not been explained the hobbit's inordinately small brain.

That's where hippos come into the picture.

Eleanor Weston and Adrian Lister of the Natural History Museum in London compared fossils of several species of ancient hippos found on the island of Madagascar with the mainland ancestors from which they had evolved.

They were surprised to find that insular dwarfing -- driven by the need to adapt to an island environment -- shrank their brains far more than had previously been thought possible.

"Whatever the explanation for the tiny brain of H. floresiensis relative to its body size, our evidence suggests that insular dwarfing could have played a role in its evolution," they conclude.
While the new studies answer some questions, they also raise new ones sure to spark fresh debate, Harvard professor Daniel Lieberman said in Nature.

Only more fossil evidence will indicate whether the hobbits of Flores evolved from Homo erectus, whose traces have been found throughout Eurasia, or from an even more ancient lineage not yet found outside Africa, he said.
