Just as I suspected, you have no fucking clue of what i'm talking about; The language barriers might be big, but don't try to play the smart-ass with me again kid.

Cro-Magnid is an archetype of the old physical anthropology which was used to describe any eurydolichomorphic individual of the present day. As of now we know that nutrition, lifestyle and climate are the key factors for any change of the plasticity of the Human body, which it can change very quickly, even in less than one generation.Originally Posted by Hellhammer
In an attempt to answer your question - which was not put in scientific terms - I'll use a phylogenetic approach:
By some 70 millennia ago, a part of the bearers of mitochondrial haplogroup L3 migrated from East Africa into the Near East. The date of this first wave of "out of Africa" migration has been called into question in 2011, based on the discovery of stone tools in the United Arab Emirates, indicating the presence of modern humans between 100,000 and 125,000 years ago.

How population phenotypes change over time is no great mystery
The slightly more wide-bodied of the ancestral leptosomic types were more adapted to the new environment, so genes for progressively wider and wider bodies were propagated.
Now, if it’s indeed true that humans originated in Africa and that non-Africans descend from a small group that crossed the Red Sea some 80-90 thousand years ago, we should expect a clear trail demonstrating this, and the clearest trail can be found in DNA. If you look at all the Y-DNA of humans, for example, you’ll see that you can join every single haplogroup into a phylogenetic tree (you can do something similar to look at the phylogeny of species too), where each mutation can be traced back to an ancestral haplogroup until every single one converges. Let’s say you have some hypothetical current and ancestral haplotypes that look like this:
...and you want to give the most parsimonious tree to explain it, it’s this:
You can do something like this with the Y-DNA and mtDNA of humans. For example, my Y-DNA is R1a. I can trace this all of the way back to Africa by looking at the mutation tree. A lot of the geographical specifics are still very much debated, but with our current knowledge it would probably be roughly:
My subclade of R1a (somewhere in Europe) -> R1a (South Asia) -> R (Central Asia or Middle East) -> P (Central Asia/Siberia) -> K(xLT) (South Asia/Central Asia) -> K (South or West Asia) -> IJK (Southwest Asia) -> F (South or Southwest Asia) -> CF (Southwest Asia) -> CT (East Africa) -> BT (Africa) -> “Y-chromosmal Adam” (Africa)
It’s funny how you dogmatically come to such a conclusion before I even respond.

Ouch. You just got your ass handed to you, Hell old boy. How embarrassing for you.Maybe you should learn to think before you open your big mouth and spew your verbal diarrhea.

It’s funny how you dogmatically come to such a conclusion before I even respond.I was expecting your response tomorrow. Sorry to burst your bubble tho, but Halogroups doesn't directly correlate with someone's Phenotype, so your explanation is biased. I was expecting some environmental/anthropological explanation rather than genetical gibberish that I do already have some knowledge about.
Say, if you do a genetic test to a Mexican Mestizo with predominantly Caucasian ancestry he will probably gonna came out with his Y-DNA being R1b1b2 due his paternal forebears being Spanish Conquistadores, still he could look as dark as chocolate, despite the fact of having European Y-DNA. So that doesn't say much about morphological variations really.
Then again, you DIDN'T answer my question, I wanted to know place of origin of the said races, how they theorically evolved from being Black to being White -without- the aid of genetic gibberish. You are just a hard headed guy aren't you? I'm not willing to keep up with your childish ramblings untill you show me some adaptative anthropological proofs of the so called ' White man evolution '

Dude, stop with your genetic shit, i'm asking about anthropological proofs of the ' missing link ' so to speak. Where are the transitionary specimens of Blacks and what we today know as Cromagnids? Do you have anything to back up your statements?

Whatever, I said I was out of this conversation untill you could provide me with some solid proofs of human evolution, and you personally haven't give me any solid argument whatsoever.I'm the guy who's laughing at you.

Look around you, Humanity is a big phenotypical cline, each phenotype is transitional to some other phenotype. And of course transition is determined by geography, climate, nutrition and lifestyle.
I don't really see the mistery here, it's a pretty down to earth subject.
