Exile of Roma founders from India c. 1405 years ago - Genetic study
in PLoS of Dr. Gyaneshwer Chaubey and team. Re-evaluate I-E/ANE
 studies. 
Proponents of Aryan Invasion/Migration/Trickle-in/Tourist theorists
should re-think and re-evaluate the formation of Indo-European
languages after contacts between Hindu civilization people and
.people of Ancient Near East.
Congrats to Dr. Gyaneshwer Chaubey and Team for such a precisely
calibrated genetic study.

CCMB traced the origin of Roma (Gypsy) population

The origin and migration of Roma (Gypsy) has been curious among
people across the world. Although the linguistic and genetic studies
on European Roma have traced to Eurasia, the exact parental
population group and time of dispersal has remained disputed. In the
absence of archaeological evidence and with the availability of only
scanty historical documentation of the Roma, have made the
international team of scientists led by Dr Kumarasamy Thangaraj from
the Centre for Cellular and Molecular Biology Hyderabad and Dr.
Gyaneshwer Chaubey from Estonian Biocentre and Tartu University,
Estonia; involving scientists from University of Bern, Switzerland,
University of Cambridge, UK and Stanford University, USA to trace the
founder of the European Roma, using the Y chromosome genetic
signatures. This study has been published in the recent issue of the
online journal PLoS one.

Y chromosome is inherited from father to son; to grandson. Therefore,
all the males of a family or a population evolved from a single
founder male will possess the same Y chromosome. Based on the genetic
signatures exist on the Y chromosome, every male could be assigned to
a specific group (haplogroup), hence the paternal lineage can be
traced, using these signatures. 

Previously it has been shown that the European Roma possessed the Y
chromosome haplogroup H1a1a however, the most recent common ancestor
of European Roma, has not been identified because of the absence of
similar data from their putative homeland i.e. India. 

In this study, Scientists have screened approximately 10,000 males
from around the world, includes 7000 males belonging to 205 ethnic
populations of India, to discern a more precise ancestral source of
European Romani (Gypsy) population.

“We have compared the worldwide phylogeographical data, for Indian
H1a1a haplotypes with Roma and concluded that the aboriginal
scheduled tribes and scheduled caste populations of northwestern
India, traditionally referred as the Doma and also known as ‘Dalits’,
are the most likely ancestral populations of modern European Roma”,
said Dr. Kumarasamy Thangaraj. 

“Our finding corroborate the hypothesised cognacy of the terms Rroma
and Doma and resolve the controversy about the Gangetic plain and the
Punjab in favour of the northwestern portion of the diffuse
widespread range of the Doma ancestral population of northern India”,
said Dr. George van Driem – a linguist from the University of Bern,
Switzerland. 

“It is noteworthy the closest as well as matching haplotypes with the
Roma haplotypes were found only in scheduled caste and scheduled
tribe populations of Northwestern India appear to corroborate the
linguistic evidence and the most recent reconstruction of the likely
ethnolinguistic origins and affinities of the gypsies, based on
linguistic and Indological studies” said Dr. Gyaneshwer Chaubey
another member of this team.

This study also estimated that the exile time of Roma founders from
India was approximately 1405 years ago.
