How and when did the major races of humankind emerge?

Question

I'm not convinced of the Evolutionary Model (but I'm not a Creationist either), with that said, for the case of this question let us "assume" the former is true. If this is so, how and when to the differential ethnic races emerge? Was the first Homo sapiens *******, Caucasian or Mongoloid? How did the genetic distinctions of each race emerge? We are told by anthropology that Africans are black-skinned because of Africa’s high elevation (though the Congo and the coastlines are near sea level) and close proximity to the sun. Yet, English people living in South Africa are still white-skinned, and Africans have migrated around the world to cooler climates and they are still black-skinned, i.e. the Blacks of Great Britain, Chicago or Detroit. Thus, an “environmental rationale” does not seem to support this claim, but appears more like a fable and modern myth. And why are the Mongoloid Asians’ bone structure so dramatically different from the other races, having long torsos and short-legged, not to mention their completely unique eyes demonstratively different from all other races? In reality, it appears that the separate race groups are from entirely separate sources and not from one common source.

Answer 1

There is one race of humans now that it has extincted the other one about 30,000 years or so ago.

The research is simple enough even for the average person. So, do some.

Answer 2

primarily though the effects of UV rays on skin cells.As people moved though to the more Northern climes(say Europe),the people with lighter skin were able to adept and so ended up being white,black,asian,native american or whatever else they turned out to be.

Answer 3

I read recently, that the root of all Homo Sapiens DNA originated in Sub-Sahara Africa among the "Click" speaking people (Bushmen)...

From that, a secondary DNA-branch emerged, which had more diversity & variation in it. This offshoot was also in the Sub-Sahara, but nearer to the Old Ethiopia.

From this group, which is believed to have migrated to the Saudia Arabian peninsula, the rest of the world was eventually populated, and subsequently changed skin & eye colors, as well as hair textures, while adapting to specific environments...

Answer 4

The following information has been available for decades, is not only such source, and throws opinion of writer into 'dreck'

(as Jesus would say).  A quick resolution to your thought

process involves keeping something mutagenic from Oklo, Africa, in pocket next to testicles of  Question Source until mutations of future offspring present themself or not.  

P.S. :  You can put truth into a grave but it won't stay there.

Answer 5

Of course it would take more than a few hundred years or even a few thousand.  I have trouble believing that it took the 40,000 years that it is said for Europeans to have developed. I think it would take longer.  They only find bones so skin is more of a guessing game.  They don't know the color of the Neanderthal.  Neanderthal was in Europe for much longer and if they could find skin, it would be a great discovery.
