Nuances & Consequence of Genetics On Aryan Origins

Encounter With Harvard's School of Genetics : Nuances & Consequence of Genetics On Aryan Origins 
( David Reich, Lal Ji Singh, Priya Moornjini, K. Thangaraj)
================================================

All my patriotic friends.

Have seen most of us keep quoting outcome of a genetic research  which was facilitated in India by Dr Lal Ji Singh (former VC of BHU)  under David Reich director of research program, it's results were published in 2009 which was the first phase.

Millions of young Indians mostly from technology, engineering and humanities keep quoting this research of 2009 in which Dr Lal Ji Sigh was involved.

Second phase of research was carried out in 2012, which corrected several outcomes of preliminary research of year 2009 and stamped migration of Indo-Europeans from Uralic mountains to India, moreover created two objectionable terms (ANI) and (ASI)   which most of Indians and many of my friends are not aware.

I was an early observer of what has been happening in Harvard and kind of popularity Dr Lal Ji Singh has been earning in India and how he was silently supporting a team that was undercutting our umbilical chord with our own history. Having studied genetics and grasping concepts like ( Y-Haplogroup or mtDNA ) for some two months, I filed a direct petition on Harvard's team who carried out the research studies.

*****************************************************************
Below is explanation given by real researchers,  firstly by Priya though I expected Dr Lal Ji Singh and secondly by the director of research program Dr David Reich.

Dr David Reich confessed that genetics is not equipped for finding out questions like origin of Aryans as sample genetic pool of that antiquity is not available. Priya though gave rounded clarifications but she also confessed that they used linguistics to relate genetic findings to solve historical issues. She cited Michael Witzel's linguistics to corroborate her genetics findings.

Dear friends, it's clear that if linguistics goes wrong, genetics w'd obviously go wrong and if genetics go wrong linguistics w'd for sure go wrong as it moves in circle.

Pls never be oblivion to basics that no human gene records what language humans speak and to what direction humans travel which is the essence of this encounter with entire Harvard team, the super experts who captures so much space in Indian media and millions of youth and senior citizens, academicians feel proud in following them.

!! Never stop raising questions, Reputation is a junk !!

Read and Enjoy

Response From Priya Moorjani

Dear Lalit Mishra,

Thank you for your interest in our work. I am cc'ing David Reich and  Kumarasamy Thangaraj who might have further comments related to your questions. Please see my responses to your questions below -

LM #1 - How you ensure that an expansion of ANI ( North Indian Vedic Aryans) hasn't happened from India to Europe that is what Rigveda suggests to us, I have attached two maps based on Rigvedic and Mahabharata accounts for easy understanding of the ANI ( North Indian Aryan) to your team.

Priya#1 -  Our analysis shows that many middle and upper caste groups in India have evidence for a complex history of ANI-ASI mixture, with signals of multiple layers of ANI ancestry from slightly different ANI ancestral populations.

This in combination with the evidence from linguistic data analysis (which does not support the position of Sanskrit at the root of the Indo-European language tree), suggests that the migration happened from West Eurasia (from Caucasus, Middle East or Europe) to India.

LM #2 -   How do you estimate age of the admixture of people through the study hypothesis.

Priya#2 - When two populations with distinct ancestries such as ANI and ASI mix with each other, the descendants (Indians) inherit long chromosomal segments from each ancestral population. After the mixture, in each generation due to recombination, these long segments get broken down. However, the key insight is that the length of these segments are still informative of the time of the mixture. We study the extent of correlation in ANI and ASI ancestry across the genomes of the Indians to estimate the time of the mixture. For details of our method (ROLLOFF), please see

[ Moorjani et al Plos Genetics 2011, Patterson et al Genetics 2012 and Chakraborty and Weiss et al 1984]

LM #3 -  What is your view on exceptions found in this research’s outcomes, where it leads to us, how you handled such exceptions

Priya#3 - I am entirely sure if I understand your question. The main exceptions in this study I would say includes groups with a simple history of ANI-ASI ancestry - some lower caste and tribal groups have a history consistent with a single wave of mixture, to the limits of our resolution. This suggests that as early as 4,000 years ago there were unmixed groups of ANI and ASI residing in India.

I hope I have answered your questions. Please email us if you have any further questions.

Note# In her part of the same paper, Pritya had written which she skipped while responding to my questions put to her -

“The bulk of the Rig-Veda describes a society in which there is substantial movement among groups"

Further clarification produced by Dr David Reich

Dear all,

I just wanted to add my own comment, which is that in my opinion, the genetic data currently do not currently show the direction of migration or date of migration.

All the data show right now is that major population mixture of very different populations occurred in the history of Indian groups 2000-4000 years ago. As Priya’s paper in 2013 showed, before 4000 years ago there were unmixed ANI and ASI groups in the Indian subcontinent, but today, there do not seem to be any.

Some migrations must have occurred in the past to explain this mixture of two highly different populations, but we do not know when – they could have occurred shortly before the mixture, or thousands of years before, or in principle even older than that.

Right now, I am not convinced that
there is any evidence of a genetic link between Europe (in particular) and India within the last approximately ten thousand years, although my opinion could change on this with more data.

Yours,
David
