Khoisanid people

coming off a question and answers thread, I thought i would start one on the Khoisan people.

I found this article which touches on what penguin posted.

"Another group that has been the subject of much discussion is the Khoisanid peoples (including the Hottentots, San, !Kung). The San (Bushmen) in southern Africa are a group that physically looks quite different from other Negroids. Baker (1974), and Coon (1965) among others, have argued they are as different from Negroids as Caucasoids are, and should be treated as a separate race from other Negroids. The genetic data reported here shows them to differ more from other sub-Saharan Africans than any of the sub-Saharan groups differ from each other (p. 175).

Interestingly, the San are closer to Near Eastern populations than the adjacent Bantu populations. Their gene frequencies are consistent with their being 56% Near Eastern, with the remainder African. Given that the territory they currently occupy is distant from Caucasoid territory, this is puzzling. However, a possible theory supported by historic remains and linguistic traces, is that they were once were in East Africa, possibly as far north as Egypt. Some mixing with Caucasoids could have occurred then.

The Ethiopian populations, which appear to be a similar Caucasoid, Negroid mix show a considerable genetic distance from the San, suggesting if both are a result of mixture, the mixtures occurred at different times.

An alternative hypothesis, that is supported by mitchorondrial DNA evidence and the San's distinctive morphology, is that they are a relict population of an early race of humans whose territory once covered much of Africa, and are the ancestors of all humans (p. 176). It is interesting to see how modern genetic data supports the earlier idea of Coon that these were a relict of the original populations from which other groups split (1963, 1965). Here the resemblance with the Near Eastern populations is explained by these populations having been derived from the San." Source

I would like to learn a bit more about this group, being unique (and arguably archaic),

The national geographic genetic map

They have some the highest frequencies of both M91 Y chromosome and L1 mitchorondrial DNA. This makes the more directly related genetically to the 'Adam and Eve' of the homo sapians.

Edit:


Some studies that mention Khoisan genetics. (my colouring)

"Hierarchical Patterns of Global Human Y-Chromosome Diversity"

"The root of the gene tree in figure 1 fell between two sets of haplotypes (h1�h4 and h5�h10) that are entirely restricted to the continent of Africa (table 1), thereby supporting the hypothesis of an African origin
of contemporary NRY lineages (Hammer et al. 1998; Underhill et al. 2000). Haplotype 1 represents the ��ancestral�� human NRY haplotype (previously designated haplotype 1A in Hammer et al. 1998), which is found at relatively high frequencies in Khoisan populations. Haplotype 2, a one-step neighbor of h1, was found in;14% of Ethiopian chromosomes in this study, as well as in 42% of Underhill et al.�s (1997) Sudanese samples. The predominantly East African distribution of h1 and h2 (data not shown) lends support to the hypothesis of a remnant archaic gene pool along the African rift and a possible wider East African range for the ancestors of
the Khoisan (Scozzari et al. 1999). Other than the two aforementioned sets of haplotypes confined to Africa and a set of YAP1 haplotypes (h13�h15), all haplotypes in the remainder of the tree were absent or very rare in sub-Saharan African populations"

thanks Pinguin will do a search in here and on the wider web.

Just edited in some genetics talk into the first post

White Nationalists are a bunch of idiots, like all racists. I don't believe that's a good argument at all. Don't you think?

Originally posted by pinguin   (By the way, just as a curiosity, don't you know there are lot of White Americans that have Black African ancestors in the family tree? They look 100% White but genetics don't lay. If you get interested into that, just let me know)

Yes i do know that, but most of the time they'll try to hide it......I'm pretty sure everyone of us humans are mixed with more things then we think.....But yeah i am a little interested in the genetic thing...If you got a link i'll check it out.
