By human I mean
Homo sapiens.
It seems to me that it's very possible that in Europe, where only
Homo neanderthalensis resided and where some
Homo sapiens resided, there could have been some interbreeding taking place. Since the two species have very similar DNA I think impregnation was possible.
See how they existed in the same place at the same time:
As you can see,
Homo rhodesiensis, which are known to be the ancestors of
Homo sapiens, look nothing like what whites look like today.
Whites, in my opinion, look a lot more like
Homo neanderthalensis, which are not regarded as ancestors of humans. That species died out about 45,000 years ago.
My theory is that some of their DNA are in humans today, more so in whites, which is why they look more like them. Are whites more neanderthal than others (and therefore less human)?
