The Bengalis Were Never Who We Thought — DNA Finally Proved It

The Bengalis Were Never Who We Thought — Ancient DNA Finally Proved It Three hundred million people live in the Bengal delta and its diaspora across the world, and almost all of them understand themselves as South Asian. Bengali. Part of the great genetic tapestry of the Indian subcontinent. That understanding is real. But when researchers analyzing the 1000 Genomes Project Bengali dataset ran their admixture analyses, they found something that separates Bengalis from every other South Asian population in a way that no cultural or linguistic history had fully captured. Bengali genomes carry a measurable and substantial East Asian ancestry component — ancestry that connects them not to the populations of the Indo-Gangetic plain to their west, but to the populations of East and Southeast Asia to their east and northeast. No other major South Asian population carries this component at the same level. The Bengalis are the most genetically distinctive population in all of South Asia, sitting at the crossroads of three entirely different streams of human ancestry that converge nowhere else in quite the same way. The Ancestral North Indian component connects them to the ancient populations of the Iranian plateau and the Eurasian steppe. The Ancestral South Indian component connects them to the most ancient inhabitants of the subcontinent. And the East Asian component — the one nobody in the standard South Asian narrative accounts for — connects them to the populations of Southeast Asia, Burma, and East Asia, whose long-standing presence at the eastern edge of Bengal left a biological trace that is still clearly visible in Bengali genomes today. On top of all of this sits the finding that has the most immediate cultural resonance for the people of Bangladesh: the Muslim majority of Bangladesh, the population that makes up most of the 170 million people in that country, descends overwhelmingly from local converts rather than from Arab or Central Asian immigrants. The DNA confirmed what historians had long suspected and what the genetic data now proves — the Islamization of Bengal was a cultural and religious transformation, not a population replacement. The Bengalis who adopted Islam remained genetically Bengali. And the Bengalis, across all their religious, national, and cultural divisions, remain one of the most genetically layered and historically complex populations on earth.
