Another reason for some to start ranking people.....ranked by the least or most neanderthal DNA. A new racism based on DNA differences. Are we brothers or what?
But it turns out that many African and Middle Eastern remains also have the HLA gene with variants and date back to pre-migration. Thus, the presence of the HLA in both humans and neanderthals are back to being: "so what? One Creator created everything anyway so there's liable to be some common traits among much of His design." (my words)
