Description: p. Series: Harper torchbooks. Knowing that the Indus civilization traded with those regions, and that those 11 individuals had little in common genetically with others buried in their regions, Reich and colleagues concluded they were likely Harappan migrants. Now working with a bank of Indus genomes presumed to be 12 individuals strong, the researchers compared their genetic signatures to DNA from other ancient civilizations in Eurasia as well as modern populations.

A resulting Indus family tree revealed that although the civilization collapsed nearly years ago, its genetic stock forms the basis of most people living in India today , the team reports today in Cell. The Science paper, also led by Reich, notes that modern people from North India also bear the genetic marks of ancient interbreeding with herders from the Eurasian steppe, a vast grassland that stretches across northern Asia, moving southward around B.

Those steppe herders carried European DNA from previous interbreeding events, the authors note, explaining the once-perplexing genetic link between Europeans and South Asians. One surprise concerns DNA related to ancient Iranians, which was previously found to be prevalent in modern South Asians.

Could an Industrial Prehuman Civilization Have Existed on Earth before Ours?

Yet the new study suggests the Iranian-related DNA in both the Indus individuals and modern Indians actually predates the rise of agriculture in Iran by some years. In other words, that Iranian-related DNA came from interbreeding with 12,year-old hunter-gatherers, not more recent farmers, Reich explains. One explanation, he notes, might be that ancient South Asians learned farming practices from their neighbors without interbreeding with them.

Figuring out exactly what happened will require more archaeological work and more ancient DNA samples from across the region, Chaubey says.
