Who built the Indus Valley civilisation?

The Harappans as Vedic Aryans

  • In the ancient DNA from Rakhigarhi, scientists identify R1a, one of the hundreds of Y-DNA haplogroups (or male lineages that are passed on from fathers to sons). They also identify H2b — one of the hundreds of mt-DNA haplogroups (or female lineages that are passed on from mothers to daughters) — that has often been found in proximity to R1a.
  • There is no reason whatsoever to think that this would be the research finding, but if it is, it would cause a global convulsion in the fields of population genetics, history and linguistics. It would also cause great cheer among the advocates of the theory, which says that the Indus Valley civilisation was Vedic Aryan.
  • The global churning would be caused by the fact that such a finding would go against the current understanding of the spread of Indo-European languagesacross Eurasia and also against current genetic evidence. R1a is the haplogroup most closely associated with Indo-European language speakers in a vast swathe of the Eurasian landmass, ranging from Ireland and the U.K. to Italy, France, Germany, Poland, Russia, Iran and northern India. In the majority of European countries, especially in central and eastern Europe, R1a has a frequency of 40-60%. In India, it has a frequency of about 17.5% — it is most common among north Indian Brahmins and least common among the tribals and the northeastern populations.
