Modern Europeans have a smaller proportion of Neanderthal genes in their genomes than East Asians do. New research suggests the reason lies at the feet of migrating early farmers.
A wave of migrating farmers from the ancient Middle East may be the reason why modern Europeans don't carry as much Neanderthal DNA as today's East Asians do, a new study finds.
All humans with ancestry from outside of Africa have a little bit of Neanderthal in them — about 2% of the genome, on average. But people with East Asian ancestry have between 8% and 24% more Neanderthal genes than people of European ancestry. That's a bit of a paradox, because fossil evidence suggests Neanderthals lived in Europe. Why, then, should East Asians carry more of those genes today?
Now, a new study posits a solution to this conundrum: While a wave of human migration out of Africa before at least 40,000 years ago brought Homo sapiens — who were hunter-gatherers — into contact with their Homo neanderthalensis cousins and led to interbreeding, a later wave of H. sapiens migrating about 10,000 years ago diluted Neanderthal genes in Europe only. This was the movement of farmers with minimal Neanderthal ancestry from what is today the Middle East and southwestern Asia into Europe. These early farmers mixed with local hunter-gatherers, bringing a more H. sapiens-flavored genome to the region. The Homo sapiens who settled East Asia by around 60,000 to 70,000 years ago did not undergo this dilution from newcomers...
Research suggests that having Neanderthal genes didn't lead to any major survival advantages or disadvantages for humans, so natural selection is probably not the reason why some populations carry more of these genes than others, Hawks told Live Science...

Neanderthal women found Euro men unattractive
I question that statement sir. I am reasonably sure that I have never seen a Neanderthal portrayed as a tall blue-eyed blond human. For starters the typical skull attributed to a Neanderthal looks nothing like the head of a Norseman. It would be statistically unlikely for the Neanderthal skull to evolve the shape to the newer version in a relatively short time.
Although maybe just as likely as Cho BiDung winning in 2020.
The percentage is probably higher than is (or perhaps can be) known, due to the small number of Neander-emains that have had DNA sequenced. Ya go to research with the DNA ya have. But the current average amount of Neandertal DNA that moderns carry is about the same as we get from 46 of our 64 6th-great-grandparents. That suggests that, due to the age of the N samples, a very large number of our ancestors were them, and Them is Us.
Whoops, sorry, 4th great-grands...
Given how isolated the Neanderthals were in Europe before they had contact with anyone from the wider world in the Ice Age-and that they lived in smaller groups due to limited resources in a frigid environment-they were likely more inbred than than an Egyptian royal family, and declining in numbers by the time anyone else came along for them to breed with-their lower fertility rates got them absorbed by the more numerous H Sapiens-I doubt that wholesale massacres were the cause...
The Anatolian Farmer hypothesis has been abandoned and disavowed.
Hogwash, IMHO...
“Their clans constantly fought ferociously and ate each other.”
Archaeological finds tell us Neanderthals were cannibals too. But, then again, so were early Homo Sapiens.
I'm guessing they were just absorbed into the larger human population. Like they're hoping to do with whites.
Seen any connections with ancient Indigenous Americans?
Just did some reading more current than what I was going on which was several years old.
Seems they are questioning whether red hair came from the neanderthals. However, the neanderthals had red heads and blonds.
Non-African humans average 2% neanderthal DNA. The older reading on the subject I’ve done had Norse as high as 12%. Hybrids can take on different characteristics than either parent or one side can dominate in specific areas.
Reading the current reports, I think they are less sure than a few years ago. Formerly, the thought Neanderthal interaction happened only 60K years ago, now they are saying 250K years ago. Also, that it maybe multiple interactions.
Interesting, but we will likely wait years before they have a firmer knowledge base.
