The Indian origin of paternal haplogroup R1a1(*) substantiates the autochthonous origin of Brahmins and the caste system.
Sharma S. et al.
摘要:
Many major rival models of the origin of the Hindu caste system co-exist despite extensive studies, each with associated genetic evidences. One of the major factors that has still kept the origin of the Indian caste system obscure is the unresolved question of the origin of Y-haplogroup R1a1(*), at times associated with a male-mediated major genetic influx from Central Asia or Eurasia, which has contributed to the higher castes in India. Y-haplogroup R1a1(*) has a widespread distribution and high frequency across Eurasia, Central Asia and the Indian subcontinent, with scanty reports of its ancestral (R(*), R1(*) and R1a(*)) and derived lineages (R1a1a, R1a1b and R1a1c). To resolve these issues, we screened 621 Y-chromosomes (of Brahmins occupying the upper-most caste position and schedule castes/tribals occupying the lower-most positions) with 55 Y-chromosomal binary markers and seven Y-microsatellite markers and compiled an extensive dataset of 2809 Y-chromosomes (681 Brahmins, and 2128 tribals and schedule castes) for conclusions. A peculiar observation of the highest frequency (up to 72.22%) of Y-haplogroup R1a1(*) in Brahmins hinted at its presence as a founder lineage for this caste group. Further, observation of R1a1(*) in different tribal population groups, existence of Y-haplogroup R1a(*) in ancestors and extended phylogenetic analyses of the pooled dataset of 530 Indians, 224 Pakistanis and 276 Central Asians and Eurasians bearing the R1a1(*) haplogroup supported the autochthonous origin of R1a1 lineage in India and a tribal link to Indian Brahmins. However, it is important to discover novel Y-chromosomal binary marker(s) for a higher resolution of R1a1(*) and confirm the present conclusions.

印度人也是的,非得要证明M17是印度土著,完全不顾R1b的存在。

印度人在学术上有点韩国人的意思,民族主义强烈,主观臆断(甚至可能编造数据)。一拿到国际学术会议上,立马玩完 :Q :lol

文明古国应该都有这毛病:lol

印度的高频未必能排除后期生存环境适宜群体发展导致的可能性

我觉得婆罗门应算是人类学意义上的族内通婚的隔离群体,那么,某个单倍群占主要就很好理解了。
