R1b-V88 haplogroups were identified in ancient Neolithic individuals in Germany, central Italy, Iberia, and, at a particularly high frequency, in Sardinia. A part of the branch leading to present-day African haplogroups (V2197) was already derived in Neolithic European individuals from Spain and Sardinia, providing further support for a North ...

2010年1月6日 · The incorporation of these new mutations into a phylogeny of the R1b haplogroup led to the identification of a new clade (R1b1a or R-V88) encompassing all the African R-P25 * and about half of...

2018年2月13日 · One of the theories I proposed in the Indo-European demic diffusion model since the first edition – based mainly on phylogeography – is that R1b-V88 lineages had probably crossed the Mediterranean through southern Italy into a Green Sahara region, and distributed from there throuh important green corridors, humid areas between megalakes.

R1b-V88是撒哈拉以南黑非洲的一个特别分支，在喀麦隆北部60％-95％的男性中发现。 单倍群R*起源于末次盛冰期（Last Glacial Maximum，26500-19000年前）之前的北亚地区（North Asia）。 这个单倍群最早是在西伯利亚中南部阿尔泰地区，一个24000年前男孩的遗骸里发现的 (Raghavan et al. 2013)。 这个人属于旧石器时代游荡在西伯利亚和欧洲部分地区的一个猛犸象猎人部落（mammoth hunters）。 这种旧石器人群似乎对现代欧洲人和南亚人祖先的常染色体 …

2016年12月1日 · It brought to Africa a Y chromosome lineage (R1b-V88) whose closest relatives are widespread in present-day Eurasia; we estimate from sequence data that the Chad R1b-V88 Y chromosomes coalesced 5,700–7,300 years ago. This migration could thus have originated among Near Eastern farmers during the African Humid Period.

R1b-V88 is found among the native populations of Rwanda, South Africa, Namibia, Angola, Congo, Gabon, Equatorial Guinea, Ivory Coast, Guinea-Bissau. The wide distribution of V88 in all parts of Africa, its incidence among herding tribes, and the coalescence age of the haplogroup all support a Neolithic dispersal.

All the African R1b chromosomes, with the exception of one eastern- and a few northern-African R-M269 chromosomes, turned out to belong to the haplogroup R-V88. About one third of the African R-V88 chromosomes carried mutation V69, which was not observed outside Africa.

The incorporation of these new mutations into a phylogeny of the R1b haplogroup led to the identification of a new clade (R1b1a or R-V88) encompassing all the African R-P25(*) and about half of the few European/west Asian R-P25(*) chromosomes.

2018年3月4日 · R1b支系V88，在非洲下撒哈拉常见的一个遗传标记，在喀麦隆北部的各部落人群中，比例从60%到95%不等。 旧石器时代的猛犸猎人. 人类Y染色体DNA单倍型R*起源于末次盛冰期（26,500-19,000 年前）之前的北部亚洲。 在中西伯利亚南部的阿尔泰地区一具死于24,000年前的男孩遗体被发现，之后在DNA检测中鉴别出单倍型R*。 这个男孩属于一个在旧石器时代游猎在从欧洲到西伯利亚的猛犸猎人部落。 与之相对应的常染色体被发现散布于现代欧洲到南西伯 …

With a 95% probability, the most recent common ancestor of all members of haplogroup R-V88 was born between the years 16,367 and 11,791 BCE. The most likely estimate is 13,916 BCE , rounded to 14,000 BCE .
