In contrast, some of the other white South Africans were Ashkenazi Jews, and others seemed to be English with no African ancestry.<\/p>\n<p>Last year the paper, <a href=\"https:\/\/bmcbiol.biomedcentral.com\/articles\/10.1186\/s12915-020-0746-1\">Patterns of African and Asian admixture in the Afrikaner population of South Africa<\/a>, investigated the issue thoroughly. The authors investigated 77 Afrikaners on high density chips, and they found ubiquitous ancestry from non-European population groups:<\/p>\n<p>1) Likely Khoi ancestry related to the \u01c2Khomani<br \/>\n2) Sub-Saharan African ancestry, but closer West Africans and even East Africans than neighboring Bantu<br \/>\n3) Indian ancestry<br \/>\n4) East Asian ancestry<\/p>\n<p>The East Asian ancestry is almost certainly from what is today Indonesia. The ubiquity of Indian slaves in the 17th century should make #3 unsurprising. And the Khoi people were indigenous to the Cape when the Dutch arrived.<\/p>\n<p>The second component is harder to parse. But, it seems that the arrival of a few external slave ships was critical. The non-European admixture into the Afrikaners dates to the earliest period of settlement, not to later centuries when there was much more ubiquitous contact with Bantu-speaking populations. By then the whites were endogamous. Or, the mixed offspring were being assimilated into the Coloured community, rather than into the whites.<\/p>\n<p>Curiously, the European ancestry of the Afrikaners was not subject to a strong bottleneck. Perhaps this is due to the heterogeneity of its source? Dutch, French Huguenots, and Germans, all played a role.*<\/p>\n<p>* Not an <a href=\"https:\/\/www.biorxiv.org\/content\/10.1101\/009340v1.full.pdf\">apples-to-apples comparison<\/a>, but it is clear that self-identified non-Hispanic whites of European heritage have a much lower proportion of non-European ancestry than Afrikaners.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>About seven years ago I got my hands on some white South African individuals from the Family Tree DNA database.
