We perish because we know not… #TLENews
The partial skull of an anatomically modern human who lived alongside the Neanderthals about 55,000 years ago has been unearthed from a cave in northern Israel, scientists say.
It is one of the oldest non-African skulls of Homo sapiens and comes close to the date when modern humans migrated out of Africa, eventually to colonise Asia, Europe, Australia and the Americas.
Scientists unearthed the cranial fragments from Manot Cave in West Galilee, a prehistoric site with an impressive archaeological record of flint and bone artefacts. Dating has placed the skull within the period 50,000 to 60,000 years ago, a time when Neanderthals were also known to have inhabited the same region.
“It has been suspected that modern man and Neanderthals were in the same place at the same time, but we didn’t have the physical evidence. Now we do have it in the new skull fossil,” said Bruce Latimer, a palaeontologist at Case Western Reserve University in Cleveland, Ohio, who took part in the study.
“Modern humans and Neanderthals likely encountered each other foraging for food,” Dr Latimer said.
Modern humans share a small percentage of their DNA with Neanderthals, suggesting that limited interbreeding had taken place at some point in the past. However, it is not known when this contact took place, or whether it had occurred somewhere in Europe or the Middle East.
The overall shape of the Manot cranium is more similar to the ancient fossil skulls found in Europe compared to other modern human skulls found in the Middle East, according to the study published in Nature led by Israel Hershkovitz of Tel Aviv University.
“This suggests that the Manot people could be closely related to the first modern humans who later successfully colonised Europe,” the authors said, adding that the skull suggests that interbreeding with Neanderthals could have taken place in the Middle East rather than in Europe.
Professor Chris Stringer, head of human origins at the Natural History Museum in London, said the skull is the first “well dated” modern human to have lived in the time frame when interbreeding with Neanderthals was a possibility.
“Without accompanying DNA data it is impossible to say whether the Manot skull contains Neanderthal DNA from an interbreeding event, but its resemblance to [Europeans and Africans] suggests that any Neanderthal influence on its skull shape is minimal.” Professor Stringer said.
“Manot might represent some of the elusive first migrants in the hypothesised out-of-Africa event about 60,000 years ago, a population whose descendants ultimately spread right across Asia, and also into Europe,” he said.
“Its discovery raises hopes of more complete specimens from this critical region and time period,” he added.
