After doing genetic testing it has been revealed that Jatars and their descendants can trace back their roots to a European. This original ancestor was white and this is so for all the descendants belonging to the R-M198 haplogroup. This haplogroup originated in Central Asia, the Indian Subcontinent, Eastern and Northern Europe. The parent haplogroup is R-M198 and the age of this haplogroup is 10,000 years.
(More technical information: The more precise predicted Haplogroup is R-M512. Haplogroup R originated in Central Asia. Most descendants belong to one of two major lineages. They are present at low frequencies across Central Asia, South Asia, and Europe.)
3000 years ago our ancestors were from the Kurgan culture. These people are believed to be the first speakers of the Indo-European language group. Descendants of these people (example, the Jatars) are found in Slavic populations (native to Central Europe, Eastern Europe, Southeastern Europe, Northeastern Europe, North Asia and Central Asia) in Europe, India, and Central and Western Asia.
This is the migratory map of the haplogroups taken from familytreedna.com (Please go to this link if you want to test your DNA):
The Jatars are an offshoot of the R1a haplogroup which is basically East European or Central Asian in origin.
Sure, if we go back far enough we are all from Africa, but the Jatars are the offspring of those who went northwards, settled in Central Asia or Eastern Europe or thereabouts and then travelled down into India a few thousand years ago.
The presence of this particular haplogroup (R1a) is found more commonly in the YDNA (passed on through the male line) of Indians, and therefore it is believed that these people did not enter India as a migratory group but were invaders. They have a mention in the Rig Veda which was written thousands of years ago and are called “Aryans” if you believe that theory. There is no evidence of these people being in India beyond the last few thousand years and possibly have been present in India only for about 1000 years.
If we go beyond that, it is clear is that they lived on the Indo-Gangetic plains about 15,000 years ago, and were Indo-Scynthians. A significant number of people from the western side of the Indian sub-continent, ie Sindhis, Gujaratis and Punjabis also share this haplogroup (R1a). This haplogroup is more common amongst the Brahmins of India, even found to some extent amongst South Indian Brahmins, but it is not found in Deshastha Brahmins who were here long before them.
