Y-DNA genetic evidence reveals several different ancient origins in the Brahmin population
2021
Mahal, David G.
The ancient geographical origins of Brahmins—a prominent ethnic group in the Indian subcontinent—have remained controversial for a long time. This study employed the AMOVA (analysis of molecular variance) test to evaluate genetic affinities of this group with thirty populations of Central Asia and Europe. A domestic comparison was performed with fifty non-Brahmin groups in India. The results showed that Brahmins had genetic affinities with several foreign populations and also shared their genetic heritage with several domestic non-Brahmin groups. The study identified the deep ancient origins of Brahmins by tracing their Y-chromosome haplogroups and genetic markers on the Y-DNA phylogenetic tree. It was confirmed that the progenitors of this group emerged from at least 12 different geographic regions of the world. The study concluded that about 83% of the Brahmins in the dataset belonged to four major haplogroups, of which two emerged from Central Asia, one from the Fertile Crescent, and one was of an indigenous Indian origin.
