Neanderthal Sites and Migration Routes of Modern Humans into Europe 40,000 years ago

In a series of histograms (graphs showing the distribution of genome and population data), Hawks shows that Asian and European genomes have significantly more Neanderthal DNA than African genomes. The averages for Asian and European samples are around 3% higher than the average for African samples. Whatever gave Africans some degree of similarity to Neanderthals, non-Africans seem to have received around 3% more of it.
Europeans average a bit more Neanderthal DNA than Asians, showing that Europeans probably mixed with Neanderthals as they moved into Europe, adding a secondary mix of Neanderthal DNA into their genome beyond the primary mix shared by their respective ancestors.
The differences in Neanderthal admixture between populations within regions is more interesting. For example, Tuscans have the highest level of Neanderthal similarity of any of the 1000 Genomes Project samples. They have around a half-percent more Neanderthal similarity than the British or the Finnish. This could be show a north-south geographical difference in Neanderthal ancestry, but later population movements in Europe probably masked a significant part of the Upper Paleolithic gene pool. However, the persistence through time of extra Neanderthal ancestry in southern Europe needs further study.
Populations within East Asia also show differences in Neanderthal similarity. North China has a bit more Neanderthal, on average, than South China according to the samples, though all are identified as ethnic Han Chinese.
In Africa, the Yoruba of Nigeria have substantially more Neanderthal similarity than the Luhya of Kenya. This is puzzling, because the geographic location of the Luhya in East Africa seems better placed for Neanderthal similarity to appear, whether through ancient population structure or through the backmigration into Africa of Neanderthal descendants. Instead, the Yoruba in West Africa are the recipients of Neanderthal genes.

Which population in the 1000 Genomes Project samples has the most Neandertal similarity?

Thanks Max in Utah for the link!The Neandertal Enigma"Frayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

...and I thought moozlums were most similar.
Muzzies are most similar to their female cousins/wives.
Anyway, aren’t you being a *little bit* hard on the poor suffering Neandertals?
Surely they must mean the Calabrians???
Cue Tusken raider image.
Q:”where can the greatest concentration of muzzie DNA be found in the Mideast?”
A: “goats.”
I don’t know much about genetics but I suspect some aspects of genetics will be common to life.
Shades of “Five Million Years to Earth” aka “Quatermass and the Pit” (1967).
Neanderthal chicks are easy.
That’s only hearsay, I’m sure. ;’)
So much inbreeding, they’re down to a single helix.
That’s a good one!
That explains the Scandinavian Death Metal culture.
Ah. Here, indeed, is a ‘man’ for all seasons.
Shove a candle up his backside as a bookmark.
When they’re talking 1/2 % differences, is that just another experimental distinction without practical significance?
