That is undeniable. That is clear now. So the follow-up question is can humans morph that quickly? [/QUOTE] [QUOTE] Outside central Africa, haplogroup R-V88 was only observed in Afroasiatic-speaking populations from northern Africa, with frequencies ranging from 0.3% in Morocco, to 3.0% in Algeria, and to 11.5% in Egypt, where a particularly high frequency (26.9%) was observed among the Berbers from the Siwa Oasis. --2010 Jan 6. doi: 10.1038/ejhg.2009.231 [b]Human Y chromosome haplogroup R-V88: a paternal genetic record of early mid Holocene trans-Saharan connections and the spread of Chadic languages[/b] Fulvio Cruciani, [/QUOTE]…remember that R-V88 had not been discovered in 2007…[/qb][/QUOTE]I wonder if that is actually truly the case. Could it be the data was not stable enough? [QUOTE] Haplogroup A1b. The P114 mutation, which defines haplogroup A1b according to Karafet et al. [14], had been detected in central-western Africa at very low frequencies (in total, three chromosomes from Cameroon) [16,19]. [...] ‘‘Out of Africa’’ haplogroups. All Y-clades that are not exclusively African belong to the macro-haplogroup CT, which is defined by mutations M168, M294 and P9.1 [14,31] and is subdivided into two major clades, DE and CF [1,14]. In a recent study [16], sequencing of two chromosomes belonging to haplogroups C and R, led to the identification of 25 new mutations, eleven of which were in the C-chromosome and seven in the R-chromosome. Here, the seven mutations which were found to be shared by chromosomes of haplogroups C and R [16], were also found to be present in one DE sample (sample 33 in Table S1), and positioned at the root of macro-haplogroup CT (Figure 1 and Figure S1). [/b] Six haplogroup C chromosomes (samples 34–39 in Table S1) were analyzed for the eleven haplogroup C- specific mutations [16] and for SNPs defining branches C1 to C6 in the tree by Karafet et al. [14] (Figure S1). Through this analysis we identified a chromosome from southern Europe as a new deep branch within haplogroup C (C-V20 or C7, Figure S1). Previously, only a few examples of C chromosomes (only defined by the marker RPS4Y711) had been found in southern Europe [32,33]. To improve our knowledge regarding the distribution of haplogroup C in Europe, we surveyed 1965 European subjects for the mutation RPS4Y711 and identified one additional haplogroup C chromosome from southern Europe, which has also been classified as C7 (data not shown). Further studies are needed to establish whether C7 chromosomes are the relics of an ancient European gene pool or the signal of a recent geographical spread from Asia. Two mutations, V248 and V87, which had never been previously described, were found to be specific to haplogroups C2 and C3, respectively (Figure S1). [b]Three of the seven R-specific mutations (V45, V69 and V88) were previously mapped within haplogroup R [34], whereas the remaining four mutations have been here positioned at the root of haplogroups F (V186 and V205), K (V104) and P (V231) (Figure S1) through the analysis of 12 haplogroup F samples (samples 40–51, in Table S1).[/b] http://journals.plos.org/plosone/article/file?type=supplementary&id=info:doi/10.1371/journal.pone.0049170.s001 [...] Supporting Information Figure S1 Structure of the macro-haplogroup CT. For details on mutations see legend to Figure 1. Dashed lines indicate putative branchings (no positive control available). The position of V248 (haplogroup C2) and V87 (haplogroup C3) compared to mutations that define internal branches was not determined. Note that mutations V45, V69 and V88 have been previously mapped (Cruciani et al. 2010; Eur J Hum Genet 18:800–807). (TIF) [/QUOTE]—Rosaria Scozzari, Fulvio Cruciani et al.
