[QUOTE]Originally posted by Troll Patrol # Ish Gebor: [QB] [QUOTE]Originally posted by the lioness,: [qb] [QUOTE]Originally posted by xyyman: This is really funny. Ha! Ha! You are missing the key point. First, R-V88 radiates/variability is OUTWARDS from Central Africa. Meaning the older version of R-V88 is inner Africa. European sub-clade of R1b is much much much younger than R-V88. [/QUOTE]R1b is Eurasian so a subclade of it is irrelevant to the fact it is Eurasian V88 is a subclade of R1b (aka M343) as we have seen in every chart posted in this thread [IMG]http://i40.tinypic.com/14tu5xt.jpg[/IMG] ^^^ This is Haplgroup R It begins on the upper left at M207 M207 is Eurasian not African So any subclades of R found outside of Eurasia arer younger The younger estimate for haplogroup the age of M207 is 19,000 years, in other words Haplogroup R Subclade V88 found at highest frequencies in Cameroon and Chad and is very rare and at low frequencies outside of Africa The R-V88 coalescence time was estimated at 5,600 9,200 year old The highest levels of V88 found outside of Africa are 1-4% in the Levant, comparitively in some tribes of Cameroon and Chad upwards of 95% V88 is believed to have been spread by cattle herding nomads _________________________ There is no need to complicate the topic Haplogroup R originates outside of Africa and is represented by the M207 mutation. It is at least twice as old as it's sub-clade R-V88 ^^^ this last sentence = /close thread [/qb][/QUOTE] :rolleyes: http://files.figshare.com/292764/Table_S1.xls [QUOTE] [i]Table S1. Haplogroup Affiliation of the Seven Chromosomes that Were Re-sequenced[/i] Haplogroup (by lineage): R1b1*(ŚR1b1a,b,c) Haplogroup (by mutation): R-P25*(ŚM18,P297,M335) Although the level of resolution of the MSY tree has been significantly increased in the last decade, its basal backbone has remained substantially unchanged. [b] The first branching in the MSY tree has been reported to be the one that separates the African-specific clade A (called clade I in 10) from clade BT (clade II-X in 10), whereas the second branching determines the subdivision of BT in clades B, mostly African, and CT, which comprises the majority of African and all non-African chromosomes.13 and 14 This branching pattern, along with the geographical distribution of the major clades A, B, and CT, has been interpreted as supporting an African origin for anatomically modern humans,10 with Khoisan from south Africa and Ethiopians from east Africa sharing the deepest lineages of the phylogeny.15 and 16[/b] The deepest branching separates A1b from a monophyletic clade whose members (A1a, A2, A3, B, C, and R) all share seven mutually reinforcing derived mutations (five transitions and two transversions, all at non-CpG sites).
