It is scientific fact that the MtDNA of our fathers is destroyed and replaced by the MtDNA of our mothers.
Its all the information I need to confirm what I have always suspected. Inter-breeding between Neanderthals and Modern Humans produced not only so-called Caucasians, but the American Indian, so-called Native or First Americans and a large part of the Asiatic population.
It has been confirmed by Brazilian rock art that this inter-breeding was not mutually acceptable, but rather a violent annihilation by one species (warlike) of another (peaceful).
Maybe, this was beneficial to the overall survival of the entire human race, but we will never know as long as we keep relying on the selective bits of information that those in power choose to release. For instance what was responsible for the Y Chromosome change in South and central Asia? How do these drastic mutations occur in climates not much different from that on the African continent?
There is something fundamentally different in our socialization. Sure there are Africans who senselessly kill other Africans but only after their cultural and social techniques have been destroyed and supplanted with that of the invader's culture.
