The only modern humans whose ancestors did not interbreed with Neanderthals are apparently sub-Saharan Africans, researchers say.
New findings suggest modern North Africans carry genetic traces from Neanderthals, modern humanity's closest known extinct relatives.
Although modern humans are the only surviving members of the human lineage, others once roamed the Earth, including the Neanderthals. Genetic analysis of these extinct lineages’ fossils has revealed they once interbred with our ancestors, with recent estimates suggesting that Neanderthal DNA made up 1 percent to 4 percent of modern Eurasian genomes. Although this sex apparently only rarely produced offspring, this mixing was enough to endow some people with the robust immune systems they enjoy today.
The Neanderthal genome revealed that people outside Africa share more genetic mutations with Neanderthalsthan Africans do. One possible explanation is that modern humans interbred with Neanderthals mostly after the modern lineage began appearing outside Africa at least 100,000 years ago. Another, more complex scenario is that an African group ancestral to both Neanderthals and certain modern human populations genetically split from other Africans beginning about 230,000 years ago. This group then stayed genetically distinct until it eventually left Africa.
To shed light on why Neanderthals appear most closely related to people outside Africa, scientists analyzed North Africans. Some researchers had suggested these groups were the sources of the out-of-Africa migrations that ultimately spread humans around the globe.
The researchers focused on 780,000 genetic variants in 125 people representing seven different North African locations. They found North Africans had dramatically more genetic variants linked with Neanderthals than sub-Saharan Africans did. The level of genetic variants that North Africans share with Neanderthals is on par with that seen in modern Eurasians.
The scientists also found this Neanderthal genetic signal was higher in North African populations whose ancestors had relatively little recent interbreeding with modern Near Eastern or European peoples. That suggests the signal came directly from ancient mixing with Neanderthals, and not recent interbreeding with other modern humans whose ancestors might have interbred with Neanderthals.

"The only modern populations without Neanderthal admixture are the sub-Saharan groups," said researcher Carles Lalueza-Fox, a paleogeneticist at the Ins ute of Evolutionary Biology at Barcelona, Spain.
The researchers say their findings do not suggest that Neanderthals entered Africa and made intimate contact with ancient North Africans. Rather, "what we are saying is that the contact took place outside Africa, likely in the Near East, and that there was a back migration into Africa of some groups that peopled North Africa, likely replacing or assimilating some ancestral populations," Lalueza-Fox told LiveScience.
This research also suggests that North African groups were not the source of the out-of-Africa migrations. Rather, other groups, perhaps out of East Africa, might have led this diaspora.
The scientists detailed their findings Oct. 17 in the journal PLoS ONE.

Atrah!!! I'd bang Rae Dawn Chong.
tl;dr
a recent study i saw was saying the exact opposite, that we never in fact mixed with them at all. who really knows, but supposedly contrary to popular belief about cavemen they had slightly larger brains than we did and were probably smarter than us.
No music, no candle light, no incense, no sexy nighties, no perfume? I couldn't do it I need the mood to be right. Just ing for the sake of ing, nay!
Yes, because all of those things existed in the time period when interbreeding with Neanderthals was occurring.
bigger brains != smarter. unless whales are the top of the intelligence chain.
well i'm sure there was more to it than that, but scientists do believe that neanderthals were at least as intelligent if not more intelligent than we are, contrary to popular belief that they were dumb and primitive people. they were actually very emotional and advanced at the time in many ways, brains weren't why they died out. they did like an entire show about this on the discovery channel.
Is that a condition when you pay Vietnamese hookers for sex?
Never partied in Viet Nam, was only on Vietnamese soil long enought to catch a plane to Japan.
One thing I heard was that it wasn't brain size that did them in, it was poorly developed vocal chords. They couldn't make as many varied sounds, which combine into word concepts, and therefor could not communicate and cooperate as well as Cro-Magnon.

Dammit, I thought this was gonna be a thread where I could trash some of the knuckledraggers I've been with
Neanderthals walked upright you racist.Dammit, I thought this was gonna be a thread where I could trash some of the knuckledraggers I've been with
Sex with no romance, nay~~~~~~~
