[QUOTE]Originally posted by Elmaestro: [QB] [QUOTE]Originally posted by Ish Gebor: [qb] There are many aboriginal "black" ethnic groups in North Africa and the Haratin happen to have a farmer legacy, ironically. [/qb][/QUOTE]I'm a rook when it comes to North African culture/history, When you say "aboriginal," what do you mean? more specifically as a genetic subgroup how are they Identified? are they sequenced or is Henn 2012 the closest we have to a diverse sample set? they date west african admixture to what like 1500 years ago, though Araunna Dates Sahelian or non Saharan African Admixture (SNS) to over 2.2Kya, chiang Dates SNS admixture in Sardinia to roughly before & during that period as well... So are these "mixed" populations the potentially "Aboriginals" or are there un-indexed Black Saharan populations being overlooked. I also want to point out that while [b]9kya[/b] is the estimate date for this Eurasian component in SSA, Sardinia is often most typically the best reference population for ancient admixture... Sometimes called Eurasian, sometimes called San-like HG. I mention that here because... According to researchers [QUOTE]Our analysis of cross- coalescent rates suggest the population lineage [i][b]ancestral[/b][/i] to modern-day Sardinia was effectively isolated from the mainland European populations approximately 330 generations ago. This estimate should be treated with caution, [b]but corresponds to approximately 9,900 years ago assuming a generation time of 30 years and mutation rate of 1.25x10-8 per basepair per generation[/b][/QUOTE][i]Chiang 2016[/i] I eventually hope to hear/read from people about these ancestral groups in tukulers other thread, as some of these dates and components in SNS populations are a lil eye opening for me.
