How do you know Neanderthals were genetically inferior?
Because they went extinct. You guys want to be so politically correct that you are even afraid to call the neanderthals inferior. Come on! There is no chance that someone in the world right now would be offended by the statement that Neanderthals are inferior. Homo Sapiens Sapiens dominates the world today while the neanderthals are nowhere to be found. That, in itself, indicates that in terms of biological success, neanderthals are inferior to us.
Maybe we killed them off: we are nimbler, smarter, and probably more agressive than they. Our African ancestors went to Europe, the Neanderthals stayed where they were. That shows we have initiative and the smarts to plan ahead. Maybe the neanderthals are not as adaptable as us. When Europe became warmer, they were unable to cope. In any case, they are no longer here while we are in every corner of the earth.
So they found we share, what 4% of our genes? We share over 98% of our genes with the chimpanzees! Four percent of the remaining 2% is not such a big deal. Our ancestors captured and raped Neanderthal women, and then adopted the offspring. Babies are babies everywhere. We find them cute. I have no doubt our ancestors find the Neanderthal babies cute also. It is those adopted babies that contributed the genes to our gene pool over the many generations. But make no mistake, the Neanderthals are extinct. We are not them and they are not us.
This new discovery is very intriguing but it does not take away from the fact the Neanderthals are the loser species.
