(And killed, and ate.)
The oldest DNA of a modern human ever to be sequenced shows that the Homo sapiens who interbred with the Neanderthals were very modern – not just anatomically but with modern behaviour including painting, modern tools, music and jewellery.
Some previous estimates had placed the first interspecies liaison much earlier, before the emergence of these features. The new DNA sequence shows it actually happened in the middle of an age called the Initial Upper Palaeolithic, when there was an explosion of modern human culture.
– because of them. They taught us.
About 2 per cent of many people’s genomes today is made up of Neanderthal DNA, a result of interbreeding between the two species that can be seen in everyone except people from sub-Saharan Africa. The so-called Ust’-Ishim man, named after the town in western Siberia where he was found, carries a similar proportion of Neanderthal DNA in his genome as present-day Eurasians, and a combination of radiocarbon and genetic dating shows he died only about 45,000 years ago.
…The Initial Upper Palaeolithic was a period around 50,000 years ago when complex stone and bone tools appeared across Eurasia, along with body ornamentation like pierced shells and animal teeth, pigments and even musical instruments, says team member Tom Higham of the University of Oxford. It is unknown which human-like species made these sophisticated artefacts, but the finding that Ust’-Ishim man was in Siberia at this time means that it could have been modern humans, he says.
It isn’t. You know it isn’t.
“This is very exciting research that shows again the remarkable power of ancient DNA analysis to help solve seemingly intractable questions in human evolution science,” says Darren Curnoe from the University of New South Wales in Sydney, Australia.
By comparing Ust’-Ishim’s genome to various groups of modern and ancient humans, the researchers are filling in gaps in the map of initial human migrations around the globe. They found that he is as genetically similar to present-day East Asians as to ancient genomes found in Western Europe and Siberia, suggesting that the population he was part of split from the ancestors of both Europeans and East Asians, prior to their divergence from each other.
“He represents a group that settled Siberia and then disappeared without leaving descendants,” says Curnoe. “This tells us that as early humans left Africa and settled Eurasia they weren’t all successful. There were more populations than we thought, some making no contribution to living people at all.” He notes this could make it difficult to interpret human fossils found in Eurasia, since we cannot assume that they are our ancestors.
There’s no reason to bring Africa into this at all, yet you do. There is negative evidence that Africa was NOT involved. Fuck. You.
But while Ust’-Ishim man does not appear to have any modern-day direct descendants living today, he is more genetically similar to present-day East Asians than to present-day Europeans. This finding is consistent with a recently proposed theory that present-day Europeans may have got some of their ancestry from later groups that weren’t part of the initial migration into the area. “It supports that very strongly,” says Reich, one of the researchers who developed the idea.
Yes, Europe is special.

Homo sapiens is believed to have taken on Neanderthal DNA from at least two bouts of interbreeding. While sub-Saharan Africans have no Neanderthal DNA, Asian populations have more than Europeans. [DS: cough cough IQ]
Exactly, the Africa comment was wrong. There is a LACK of evidence, a definitive NO.
“We know that there are likely to have been at least two admixture events into the ancestors of present-day people – the shared event early during modern human migration out of Africa, and a second event into the ancestors of present-day Asians,” says Kelso.
How are you so fucking stupid to keep dragging Out of Africa into this?
We have proof for the latter. Genomic proof.
There is negative evidence for the former. No genetic ties whatsoever. And still, you cling.
Because there are only a few of these longer stretches, they were unable to precisely date when this later interbreeding may have happened. But whatever the date, it seems humans and Neanderthals found each other irresistible, or at least mated with each other fairly commonly, whenever we inhabited the same areas. “The timing is most likely simply a result of the fact that this is where the two groups overlapped geographically and temporally,” says Kelso.
Rather fair-skinned, aren’t they? Didn’t they have red hair? Isn’t that a recessive trait?
So, if these guys came from Africa AT ALL, they couldn’t possibly have that many recessive traits.
Out of Africa has been repeatedly demonstrated as false because they keep having to add to it. It’s now Out of Africa more than once, which defeats the core of theory, a single migration pattern!
Multi-regional Hypothesis is supported by all the evidence! All of it! It predicted all these ‘surprising’ migration flows and multiple forms of ‘human’ genome!
In 2000, the mitochondrial DNA (mtDNA) sequence of “Mungo Man 3” (LM3) of ancient Australia was published indicating that Mungo Man was an extinct subspecies that diverged before the most recent common ancestor of contemporary humans. The results, if correct, supports the multiregional origin of modern humans hypothesis.
and from http://en.wikipedia.org/wiki/Recent_African_origin_of_modern_humans#Competing_hypotheses
The multiregional hypothesis, initially proposed by Milford Wolpoff, holds that the evolution of humans from H. erectus at the beginning of the Pleistocene 1.8 million years BP has been within a single, continuous worldwide population. Proponents of multiregional origin reject the assumption of an infertility barrier between ancient Eurasian and African populations of Homo. Multiregional proponents point to the fossil record and genetic evidence in chromosomal DNA.
You mean, actual science.
One study suggested that at least 5% of the human modern gene pool can be attributed to ancient admixture, which in Europe would be from the Neanderthals. But the study also suggests that there may be other reasons why humans and Neanderthals share ancient genetic lineages.
All this new evidence into Neanderthals show these doubters of MRH are wrong.
