[QUOTE]Originally posted by Amun-Ra The Ultimate: [QB] [QUOTE]Originally posted by the lioness,: [qb] Amun-Ra do you consider Barack Obama an African? to what extent? In America he's considered to be black or is he more like a berber? [/qb][/QUOTE]Obama is obviously 50% African 50% European, but this situation in a real practical sense is completely different that the Berbers situation, or the situation of Albert Einstein or Balkans (who carry the E hg up to around 20%) because of the timeframe and it's application on the population level (not on the individual level). Those [b] people, like Albert Einstein and his ancestors grew up within a population which was mostly non-African for a long time.[/b] So beside their one line of descent along the paternal Y-DNA line, all, or almost all the other lines of descents are non-African. You can carry the E haplogroup and be 99.9% non-African (as I have shown in another thread). Obama is direct descendant of an African father and European mother, so he's 50% African. In the case of Balkans and Einstein it just happens that one line of descent which happens to be the E haplogroup one, had a lot of male descendants. In term of maternal and autosomal, they are mostly part of their respective populations. Almost all the other line of descent are part of their respective people (Jewish for Einstein, Europeans for the Balkans, European-West Asian for the Berbers). For the Balkans we can see this may be possible by the fact that they don't carry any African maternal haplogroup to significant level only the y-DNA E, so the E carriers who migrated to the Balkans were probably already part of a non-African population when they migrated to the Balkans or they would have brought African mtDNA L haplogroups with them who would still be found in the Balkans to a high degree. At the extreme case, it's possible, that only one, or very few, E carriers made his way to the Balkans but then he and his descendants had a lot of male descendants to the point of forming 20% of the male population on the Y-DNA paternal line. Obviously intermarrying with local women of European descent, while the female descendant of E carriers also intermarry with local European/Balkans people, thus autosomally they would cluster in a big way with other europeans populations. They may be 99% Europeans beside carrying the E haplogroup. [b] Imagine if the descendants of Obama, his children and his children's children only intermarry with European people (as if they were in the Levant or the Balkans). Let's say Obama married an European woman instead of an African woman. 1st generation - Obama himself 50% African possibly E carrier. Let's suppose he is. 2nd generation - The male children of Obama with a white woman 25% African 3rd generation - 12.5% African 4- 6.25% 5- 3.125% but the males would still be E carriers (if Obama was) So within only 5 generations, the E carriers descendant of a single male, Obama, are only 3.125% African despite carrying the E haplogroup. Thus the importance of analysing all lines of descents and the general context.[/b] [/QB][/QUOTE]
