Kalyanaraman and posted in December, 2005. Below is an excerpt quoting a scientific paper on the origin of Indians, with the full text available at the URL above. This particular research contradicts two key aspects of the theory, one that Dravidians came into south India from the north, and two, that the Aryan people came into north India from Central Asia.<\/p>\n<p>&#8220;Although  considerable cultural impact on social hierarchy and language  in South Asia is attributable to the arrival  of nomadic Central Asian pastoralists, genetic data (mitochondrial and Y chromosomal) have yielded dramatically conflicting inferences on the genetic origins of tribes and castes of South Asia. We sought to resolve this conflict, using high-resolution data on 69 informative Y-chromosome binary markers and 10  microsatellite markers from a large set of geographically,  socially and linguistically representative ethnic groups of South  Asia. We found that the influence of Central  Asia on the pre-existing gene pool was minor. The ages of accumulated microsatellite variation in the majority of Indian haplogroups exceed 10,000-15,000 years, which  attests to the antiquity of regional differentiation. Therefore,  our data do not support models that invoke a pronounced recent genetic input from  Central Asia  to explain the observed genetic variation in  South Asia. R1a1 and R2 haplogroups indicate demographic complexity  that is inconsistent with a recent single history.  Associated microsatellite analyses of the high-frequency R1a1 haplogroup chromosomes indicate independent recent  histories of the Indus  Valley and the peninsular Indian region. Our data are also more consistent with a peninsular origin of Dravidian speakers than a source with proximity to the Indus and  with significant genetic input resulting from demic diffusion associated with agriculture. Our results underscore the importance of marker ascertainment for  distinguishing phylogenetic terminal branches from basal nodes when attributing ancestral composition and  temporality to either indigenous or exogenous sources. Our  reappraisal indicates that pre-Holocene and Holocene-era  not Indo- European expansions have shaped the distinctive South  Asian Y-chromosome landscape.&#8221;<\/p>\n<hr \/>\n","protected":false},"excerpt":{"rendered":"<p>www.ivarta.com October 22, 2007: HPI has just come across a marvelous summary of DNA evidence with regard to the Aryan,&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-6365","post","type-post","status-publish","format-standard","hentry","category-news"],"_links":{"self":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/posts\/6365","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/comments?post=6365"}],"version-history":[{"count":0,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/posts\/6365\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/media?parent=6365"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/categories?post=6365"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hinduismtoday.com\/hpi\/wp-json\/wp\/v2\/tags?post=6365"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
