THERE'S NO SUCH THING AS SPECIES:

Cavemen among us: Some humans are 4 percent Neanderthal: A new study concludes that humans mated with Neanderthals 50,000 to 80,000 years ago, leaving traces of the Neanderthal genome in some modern humans. (Pete Spotts, May 6, 2010 , CS Monitor)

Neanderthals and anatomically modern humans occupied the same general real estate in Europe and western Asia for roughly 50,000 years until the Neanderthals went extinct some 30,000 yeas ago. Scientists have reasoned that there must have been some level of interbreeding during that time.

With these new results, "there's very strong evidence that it did occur. There was gene flow from Neanderthals to the ancestors of all modern non-Africans," Dr. Reich says. The genome comparisons the team performed indicate a small amount of interbreeding that likely occurred during the period when they first came into contact with each other some 50,000 to 80,000 years ago.


"Anatonically modern" pretty much gives away the whole game.
