New DNA evidence is solving the most fought-over question in Indian history. And you will be surprised at how sure-footed the answer is, writes Tony Joseph

Genetic research based on an avalanche of new DNA evidence is making scientists around the world converge on an unambiguous answer: yes, they did.
This may come as a surprise to many — and a shock to some — because the dominant narrative in recent years has been that genetics research had thoroughly disproved the Aryan migration theory. This interpretation was always a bit of a stretch as anyone who read the nuanced scientific papers in the original knew. But now it has broken apart altogether under a flood of new data on Y-chromosomes (or chromosomes that are transmitted through the male parental line, from father to son).
