- IDEA 1 OF 8
DNA is rewriting Indian prehistory
Joseph, a journalist, draws on recent studies of ancient and modern DNA to tell the story of who the earliest Indians were.
He argues that genetics, combined with archaeology and linguistics, now gives much clearer answers to long-debated questions.
- IDEA 2 OF 8
The first Indians came from Africa
According to the genetic studies Joseph describes, modern humans who left Africa reached India around sixty-five thousand years ago.
Their descendants form a foundation of ancestry that is still found across almost every population in India today.
- IDEA 3 OF 8
Farmers arrived from the Zagros region
Joseph describes a later movement of people related to early farmers from the Zagros mountains of Iran.
Mixing with the earlier population, they contributed to the farming communities that grew in places like Mehrgarh, in present-day Pakistan.
- IDEA 4 OF 8
Mehrgarh shows early South Asian farming
Joseph highlights Mehrgarh as one of the earliest farming sites in South Asia, where people grew barley and wheat and herded animals thousands of years before the great cities.
It shows the long roots of settled life in the region.
- IDEA 5 OF 8
The Harappans were a mixed people
Joseph argues that the people of the Harappan, or Indus Valley, civilisation came from a mix of the first Indians and the Zagros-related farmers.
Their cities, he suggests, were built by a population that had already blended over thousands of years.
- IDEA 6 OF 8
Steppe migrants brought new languages
Around four thousand years ago, Joseph writes, herders from the Central Asian steppe moved into South Asia.
He links them to the arrival of Indo-European languages, the family that includes Sanskrit and many modern Indian languages.
- IDEA 7 OF 8
Indians share deep mixed ancestry
Joseph explains how most Indians descend from two ancestral groups that geneticists call Ancestral North Indians and Ancestral South Indians, themselves products of earlier mixing.
He argues that no group in India has a pure, unmixed origin.
- IDEA 8 OF 8
Mixing stopped as endogamy spread
Genetic evidence, Joseph reports, suggests that groups in India mixed freely for a long time and then increasingly married only within their own communities.
He connects this shift towards endogamy with the hardening of caste.
