We're Part Neanderthal, Researchers Find

[12th Doctor]

To me, this seems like yet another "coffee good/coffee bad" scientific debate.  Last year, someone declared, definitively the there is no trace of Neanderthal genes in the modern human genome.

Look, its as simple as this... all variation in the genome of modern humans can be accounted for by small mutations in the known gene pool.  Modern Humans are 99.9999999999 percent similar with in their genetic codes.  There is no real, appreciable difference between Asians and Europeans, for instance, inside the actual genetic maps.  We can only track migrations of genetic populations through Haplogroup mutations.

If Modern Humans breed and had viable offspring with Neanderthals, where ever this occurred, there would be a clear, noticeable difference in the genetic heritage of that groups, compared to groups located in lands that humans settled previously, where Neanderthals were not present.  No such split exists.  Even granting migrations of people spreading the Neanderthal genes, potentially eliminating the obvious difference, the extend of presence of these genes from one group to another would be apparent, especially when you look at the more isolated African origin groups.  No such evidence exists.

That's the end of the story.
