[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by Ish Gebor: [qb] [QUOTE]Originally posted by Swenet: [qb] [QUOTE]Originally posted by the lioness,: [qb] Haplogroup R-V88 is thought to originated in thew Cameroon/Chad region [/qb][/QUOTE]You might wanna revisit [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009543;p=1#000018]that post[/URL]. The 7ky old V88 Y chromosome in Iberia casts doubt on V88 originating in West/Central Africa. It can't be in West/Central Africa and Iberia at the same time so close to its estimated age. You're better off stating that most or all of the [i]current[/i] variation of R-V88 comes from the Cameroon/Chad region. I think you might have missed that extra information because I see that you quoted an [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009543;p=1#000019]older version[/URL] of that post at the time that doesn't contain the caveats I put in there. [/qb][/QUOTE]Swenet, What are the mtDNA L* markers correlating with these West / Central African populations? [/qb][/QUOTE]Some of the more important ones with a West/Central African origin (except for L0): [QUOTE]"Among the 16 expansion haplogroups, 5 lineages (L0a1a2, L2a1f, L3b1a1, L3e2a1b, and L3e3b) showed coalescence time less than 10 kya at least by three of five estimates mentioned in Methods, while the remaining 11 lineages (L0a1a, L1b1a3, L1b1a, L2a1a, L2a1c, L2a1, L3b1a, L3e1, L3e2a, L3e2b and L3d1–5) expanded before 10 kya (see Table S2). Specially, the expansion of lineage L3d1–5 took place before the LGM. From the ages estimated above, we found that most lineages shared among populations (11/15) expanded before 10 kya, i.e. the first occurrence of farming in the land of Africa. Thus, the result of lineage expansions showed that maternal African growth could be mainly attributed to pre-Neolithic expansion."[/QUOTE]--[URL=http://www.nature.com/articles/srep00745]Zheng et al 2012[/URL] [/QB][/QUOTE]
