Dear Morganzola, I thought I'd get you with this one - maybe Lexi will approve?

Poirot.
Nah, your info is out of date the Boffins are now saying Neanderthals were not cold adapted after all, Google it.
White skin and light hair then are clearly not adaptations to climate, any more than brown skin is, these are racial traits.
The migrants from Africa were most probably pinkish White or olive skinned creatures like the San, not Negroid, who then mated with the indigenous White Europeans, Asians and Neanderthal.
What's more Negroid Africans don't have any of the residual Neanderthal DNA found in Whites and Asians and there have been no Neanderthal remains found in Africa.
The Israelis and Chinese are also pushing back the "foundation" dates even further with their latest research, 400,000 and 250,000 years respectively, sure, evidence backs up the idea of some links to Africa in a certain epoch, but as the evidence steadily pushes back the dates for Eurasian "civilisation" past that time frame the whole show falls apart.
Plus there are were all sorts of Hominids running about the place in the distant past, we're up to what? Seven or more related species of hominid co habiting the planet in fairly recent prehistory.
That's the big hangup in the Egalitarian construct of a "human race", it's adapted, if not totally contrived to fit into a White liberal world view, which sadly for Liberals is not shared by the vast majority of normal people in the world.

Dear Aquarius,

"You know the saying, "Human see, human do."
(Planet of The Apes - 1968).

Well done, Lexi.

Dumb and dumber. One person is trying desperately to prove that whites are somehow more important than everyone else and sounds like they are quoting from "Racism for Dummies". Another is trying to prove that we all descended from a single Middle Eastern man (issues with gene pool on that one).

Imagine a bunch of aliens reading this thread, what would they make of us?

I suspect their response (or lack thereof) has been encapsulated by Bill Watterson:

"The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us."

One man, his sons, their wives - eight people. There's nothing to say they were 'Middle Eastern', but were possibly drawn from a society of rich genetic variation. What are the issues with the gene pool?
