Age of Races and Sub-Races

[cosmocreator]

Has anyone tried to age the races and sub-races? They certainly
aren't all the same age. I think it would be something like this:

Negroid (various sub-races)-- 200,000 years
Australoid (oldest)-- 200,000 years
Mongoloid (various sub-races) -- 100,000 years
Upper Paleolitic Europeans -- 40,000 years
Alpine (various sub-races) -- 25,000 years
Mediterraneans (various sub-races) -- 10,000 years
Hallstatt Nordic -- 5,000 years

This is a very subjective field, and I am far from an expert, so I humbly submit the following possible periods of origin for races and subraces:
Negroid: 200,000 - 250,000 years ago
Australoid: anywhere from 600,000 to 250,000 years ago. I realize this is an extremely long age, but the primitive nature of these groups, especially Aborigines/Maoris/Melanesians, leads me to suspect that they are descended from Java Man...
Mongoloid: 75,000 - 60,000 years ago
UP Europeans: 35,000 years ago
Alpines: anywhere from 35,000 to 20,000 years ago
Mediterraneans: 15,000 years ago
Nordics: 10,000 years ago

And multicult scientists claim that the ancestral node of humans was 100,000 years ago. eyes:

I am inclined to believe your estimates more than theirs, but they did claim to do a mitochondrial DNA-based estimate of this node (by using samples from woman from all over the world). Nordis, this is close to your field. What is your opinion of that study (I'm assuming that you are familiar with it;I believe the key word pertaining to it is "african eve")?

[Stríbog]

Yes, there is a lot of that crap going around with the African Eve and Seven Daughters of Eve ideas. Mitochondrial DNA analysis is much trickier than they claim. Mitochondria are apparently descended from bacteria that were engulfed by eukaryotic cells and formed a symbiotic relationship inside them. This theory is still conjectural, however. The key to mitochondrial racial research is that mitochondria only pass to offspring from the mother, because the sperm cells are not large enough to carry them. This means they can be used to track maternal lineage. Mitochondrial Eve is supposed to be the most recent common ancestor of all races alive today with regard to matrilineal descent specifically. Mutation rates are supposed to indicate how long ago she lived. I don't buy this, because I tend toward the theory that the various races are actually different species, closely related (in a biological sense only), and that they evolved from various related species of hominid. Furthermore, mutation rates are not constant and it is difficult to guess at the time elapsed. Recently, there has been some evidence suggesting that males can actually contribute some mitochondrial DNA in rare and exceptional occurrences...
This tends to complicate the simple multiculti Eve picture that Steohen Jay Gould and the like would have us believe.

Actually, I think that I heard somewhere that this occurs for approximately one in one thousand conceptions.
