For starters, race (archaic), in the biological sense, is synonymous with subspecies. It is scientific fact that all humans alive today are of the same subspecies. Secondly, Europeans show a range of skin colors.
The origin of white pigmentation is believed to have evolved from dark pigmentation. It is an adaptation that allows photosynthesis of Vitamin D in higher latitudes where sunlight is weaker than the tropics where dark pigmentation serves to protect against skin cancer. There is a tradeoff between these two risks. Earliest Europeans probably migrated from the East, from descendants of people who had migrated out of Africa. Don't forget Neanderthals had a foothold in Europe.
The fact is there are Blacks White and Asian, we are the same specie but there must be a beginning for each so called subspecies, and genetically are some geographical clusters were the different color among European prevails.
Blacks, Whites, and Asians are all of the same subspecies or, if you still want to use the word race, of the same race. There is not enough genetic difference between them to class them as separate subspecies.
Here the assumption is any thing from Africa have to be black, Well there are Albino among the black African . At the present time it is known blacks discriminate the Albino. So there are possibilities that in previous times the genetic defect existed and different groups from Ethiopia across the horn or following the Nile river could move North . One of the more predominant cluster of Y chromoasome R is predominant in Spain the Pirinean region . That is saying that cluster have the least intermixing skin color. I like to hear some more opinion
I'm pretty sure that theory has been debunked. I believe the reason is that the genetics responsible for albinism do not match those for light skin. I'll try to look it up tomorrow (it's rather late here and I'm off to bed).
Oh dear lord.. Ermm no. Here is some reading about the evolution of skin colour.. You know, based on scientific studies and not what appears to be a white supremacist is posting on youtube: http://www.bgsu.edu/departments/chem/faculty/leontis/chem447/PDF_files/Jablonski_skin_color_2000.pdf http://humanorigins.si.edu/evidence/genetics/skin-color
I am familiar with your first referencer about the UV and the vitamine D. That does not explain how fast the change started from one color to the other color, or how many generations had to take place . But in Europa there are cluster of inhabitants that have not intermixed with other groups according to some area in the gene and those groups are in the Caucus and the norther Spain . If you look when the Ice was retreating , the inhabitants were moving North and so the genetic marker R was advancing North were the R marker is associated with a white skin population.
By the way there is no thing about supremacists it is about the least mixed white ethnics in Europa . Beside of white skin, there is nostril and lips configuration and the UV and vitamine D does not have much to do. Beside the American blacks who live in North America after possible 13 generation have not evolved the color of their skin.
It is interesting people are afraid to discuss a real issue . The eastern block was not much involved in Paleontology and it was only the west that existed , but now the big territory is going to be explored From Poland to China , we are going to see in the future 20 years that our western knowledge is not complete, and our facts might be shaken.
They are descended from a colony of the ("black") San people who migrated out of Africa around 50,000 years ago (50KYA) and settled in southwestern Asia. (The San still exist but they now live much further south in Africa.) Around 40KYA some members of this colony explored eastward and established a population in eastern Asia, becoming the ancestors of the Chinese, Laotians, Koreans, Indonesians and other "Oriental" peoples. About 30KYA some others explored northward and colonized southern Europe during an ice age, becoming the Cro-Magnon people. The Basques may be their descendants. Much later, around 10KYA, another group broke off. Some of them went northeast, becoming the ancestors of the Persian, Indic, Slavic and Baltic peoples. The rest went north and colonized Europe, replacing the Cro-Magnons (except maybe the Basques). This group were the ancestors of today's "white" western Europeans: the Hellenic, Italic, Germanic and Celtic peoples. But the Slavic people (Russians, Poles, Czechs, Slovaks, Serbs, Croats, etc.) and Baltic people (Latvians, Lithuanians) eventually pushed into eastern Europe, and today they are included in the label of "white" Europeans. They are related, although their ancestors separated 10KYA. But "white Europeans" also include the Finns, Estonians and Hungarians, who are not closely related to the other Europeans and may actually be of Mongolic origin, which would make them "Orientals." And we're not quite sure where the Albanians came from. They're not close relatives of the other Europeans.
We are all Africans. White people are Africans that mutated into pasty skinned people because the live in a crappy climate. I am not sure why white people can't jump.
I don't have problem with humanity originating in Ethiopia or Kenya ( Africa ) , Sense there were two main migration ( 60 000 years and 40 oo0 years ) , one along the coast of Indian ocean and the other by Levant and there could be an other route along the Nile river to North Africa along the Mediterranean into Spain . The question : Were thie migrant into Europa people of the same skin color and other features . I understand the African population have the largest genetic variation , That implay there could be a different migrants instead migrant of the same stock .
You seem confused. It appears that you think that lighter skinned people moved out of Africa. This is incorrect. Descendants of people who moved out of Africa became lighter skinned.
As you know I Africa specially in Ethiopia an Nigeria there are and I believe they were in the past thousands of years people with white feature, ( small lips and pointed nose and strait hair ) Those were the ancestors of the present Ethiopian and Nigerian Fulani . This were the people who migrated into Europa in about 40000 years ago . The migration 60000 years ago probable were ancestors of some other group. What happen that we in our scientific wisdom say every thing that comes out of Africa is a Bushman and they get bleached by the lack of UV produce vitamin D because of that the body does not need to produce melanin to protect itself. Keep in mind The Sahara was a plush area . that for me means there were inhabitants on the both side of the desert not only on the south side of the desert. (I have seen in some literature there were tribe in North Africa about 100000 ..120000 years ago .) http://africanpeople.wordpress.com/2009/08/04/ethiopian-women-africas-most-beautiful-women-not-true/ Perhaps this might give you some idea were some of my thinking come from
By the way Haile Selassie I, of Agaw Zagwe dynasty, is supposed to be from the time of king Salomon been 190 generation he did not turn black ,
