The Khoisan Probably took haplogroups N and y-chromosome R to Eurasia during the Aurignacian period


.

I discuss the origin  Europeans genes  in my recent paper: " Were the First Europeans Pale or Dark Skinned? http://www.scirp.org/journal/aahttp://dx.doi.org/10.4236/aa.2014.43016

 

I quote"
The traditional view for the spread of L3(M, N) across Eurasia is that the M and N macrohaplogroups originated in western Eurasia and returned to Africa as a result of back-migration. The big problem for this theory is that the proposed dates for the origin of haplogroups N and M in western Europe, date to a period when these areas were inhabited by Neanderthal people—not AMH. This supports an African origin for L3(M, N).


The craniometric evidence supports a Khoisan presence in Europe during Aurignacian times. If the Khoisan represent the ancient dark skinned European population, this reality should be able to be confirmed by genetic research.


The most archaic AMH remains come from Florished, South Africa; they date between 190 - 330 kya (Rito et al., 2013). Other ancient fossil evidence of AMH in South Africa come from Broken Hill (c. 110 kya) and the Klasis River caves (c. 65 - 105 kya). Researchers have been surprised to find Khoisan and European admixture. The idea that the Khoisan acquired Eurasian admixture via Ethiosemitic speakers is pure speculation (Pickrell et al., 2013). There is no archaeological
evidence of Ethiopians migrating into East and South Africa, but there is evidence of an ancient migration of Khoisan into Europe based on archaeological and skeletal data.


The Khoisan carry haplogroups L3(M, N). Before they reached Iberia, they probably stopped in West Africa. The basal L3(M) motiff in West Africa is characterized by the Ddel site np 10,394 and Alul site np 10,397 associated with AF-24. This supports my contention that Khoisan speakers early settled West Africa on their way to Iberia.


Granted L3 and L2 are not as old as LOd, but Gonder et al. (2006) provides very early dates for this mtDNA e.g., L3(M, N) 94.3; the South African Khoisan (SAK) carry L1c, L1, L2, L3 M, N dates to 142.3 kya; the Hadza are L2a, L2, L3, M, N, dates to 96.7 kya.


The dates for L1, L2, L3, M, N are old enough for the Khoisan to have taken N to West Africa, where we find L3, L2 and LOd and thence to Iberia as I suggested in my paper (Winters, 2011). It is interesting to note that LO haplogroups are primarily found among Khoisan and West Africans. This shows that at some point in prehistory the Khoisan had migrated into West Africa.


The first modern European reconstructed by Forensic artist Richard Neave based on skull fragments from 35,000 years ago resembled a Khoisan (Figure 1). The skull was discovered in the southwest region of Romania’s Carpathian Mountains. This supports the research of Boule and Vallois that South Africans migrated into Europe 35 kya. This genetic evidence now supports Boule and Vallois of a Khoisan migration into Europe.


The Khoisan may have introduced the L haplogroup to Iberia. The SAK populations carry haplogroups L2, and L3. de Domínguez (2005), noted that much of the ancient mtDNA found in Iberia has no relationship to the people presently living in Iberia today and correspond to African mtDNA haplogroups. de Domínguez (2005) found that the lineages recovered from ancient Iberian skeletons are the African lineages L1b, L2 and L3."
