The population of Africa has NOT been studied to determine whether or not they also have neanderthal genes. Only 15 Africans, all from the same area, were tested in the original study.
I predict that many Africans will show Neanderthal influence.
As to my lack of capitalization and some typos. I have extensive arthritis, and typing is quite difficult for me. I make some mistakes, and sadly do not always catch them. What is YOUR excuse, Torrington?
For many years, "scientists" spread the "fact' that Neanderthals could not talk. They did not have a "voicebox" nor a hyoid bone, therefore, they were incapable of speech.
But lo and behold, now they do have evidence that the neanderthals did indeed have "voiceboxes" and they have discovered a number of hyoid bones.
One more of the "truths" about the Neanderthal has bit the dust.
In reality, evidence is slowly accumulating that would appear to show that they were not all that different from modern humans, just a bit slower to adapt to changing climates.
Any being that successfully overcomes a very harsh climate, that does not have built in fur, fang or claw, has to have some degree of significant intelligence going for it. Neanderthal made weapons, and used them to hunt. Their diet appears to have been primarily meat, which means that they were very successful hunters.
In no way were they the "knuckle dragging" cave men that all too many magazines and movies have made them out to be.
