In a review published in the journal Trends in Genetics on January 25, scientists at the Chinese Academy of Sciences in Beijing discuss what we know about the genetics of ancient individuals from Eurasia (Europe and Western Asia) between 45,000-7,500 years ago. The authors summarized work that investigated the genomes of more than 20 ancients in the Eurasian family tree, including the 45,000-year-old Ust'-Ishim individual from Central Siberia...
..."But with the information from the several individuals available for ancient DNA sequencing we do have hints at interesting population structure, migration and interaction in East Asia."
The researchers learned that in Eurasia between 35,000 and 45,000 years ago, at least four distinct populations were present. These were early Asian and Europeans, as well as populations with ancestry hardly found or not at all in modern populations. By 15,000-34,000 years ago, however, DNA sequencing showed that modern humans in Eurasia are similar to either Europeans or to Asians, suggesting that a genetic Asian-European separation likely occurred prior to 40,000 years ago. By 7,500-14,000 years ago, the populations across Eurasia shared genetic similarities, suggesting greater interactions between geographically distant populations.
These analyses also revealed at least two Neanderthal population mixing events, one approximately 50,000-60,000 years ago and a second more than 37,000 years ago. This Neanderthal ancestry gradually declined in archaic ancestry in Europeans dating from ~14,000-37,000 years ago.
"Genetic studies of ancient individuals have become more frequent in recent years because of technology," says Fu. "As a result, we can now see the presence of multiple distinct subpopulations in Europe and in Asia, and these in turn contribute different amounts of ancestry to more recent subpopulations."

Well, duh................
The east - the orient - has the highest percentage of neanderthal dna on the globe.
Man....if you understand this stuff, could you please explain it to me? Because I can’t make heads or tails out of it.
I highly recommend this book.
“A Brief History of Everyone Who Ever Lived: The Human Story Retold Through Our Genes” by Adam Rutherford, Siddhartha Mukherjee

Thanks FrogMom.
45,000-year-old Ust'-Ishim individual from Central Siberia
...my ancestor, or more accurately, I carry some of that individual's DNA, as it turns out. Does it feel cold in here to anyone else? That's my Jewish genes, tramping across the DNA and through my DNA alongside this Siberian.
“The east - the orient - has the highest percentage of neanderthal dna on the globe.”
I wonder if that’s why they’re a standard deviation higher i IQ.
O.K., O.K.
Whose been mixing with the Neanderthals????
I would have thought that the northern British Isles with their ginger gene would have had a high percentage, or was that just one gene family that made it easier to absorb the suns rays in northern climes?
And where do the Denisovins show up in all this? Decided to look myself. This link discusses us, Neanderthals, and Denisovins. There are also a number of other related links at this site.

Maybe the last group of Neanderthals did to the northern isles what the muzzies are doing to the whole of Britanistan today.
I told them that they would regret not expelling the muzzies, but would they listen?
Neanderthals had have bigger brains. What is the evolution of mankind since 30 ad? Christianity forms the base of human development. Asia has little to none.
You’re comparing the spiritual with the physical.
Cultural evolution
But I was talking about genetic capacity for intelligence.
Thanks gleeaikin. Denisovan DNA showed up in my sample. I feel special.
