How are black people a new race?
Because they only showed up in the last 6-12,000 years in the context of organized agriculture.
Steve: What people did they evolve from?
We are probably talking about races that don’t even exist anymore. No one seems to know what the pre-Negroids looked like. We have skulls, but I have never seen any reconstructions. Yes, Khoisans are an ancient race, but they have not always looked like this. The Khoisan phenotype you see is only 10-15,000 years old. It’s new too.
Steve: Aren’t they just an evolution of Homo Erectus but with modern human sized brains?
This is what we all are actually. Blacks no more or less than anyone else really. Actually Africans have been evolving away from prehistoric humans longer than anyone else.
Steve: Apart from the head size, they look the same, unless the artists depictions are biased.
Negroids don’t look like Erectus or certainly Ergaster. Anyway, phenotype doesn’t mean a whole lot when comparing modern humans to prehistoric men. We’re all equally far away from them as far as I can tell. I don’t think there are any modern humans that are closer to prehistoric men than other modern humans. Aborigines look pretty primitive, but they are further away genetically from the African prehistoric base than any other humans. There are no throwbacks and it’s a nasty lie to call Black people throwbacks or imply they are closer to prehistoric men than anyone else is.
