“DNA tests on bones might conclusively end the debate on whether the Harappans were an indigenous population or migrants. Trace element analyses will help us chart their diet ¿ a higher percentage of zinc will prove they were non-vegetarians; larger traces of magnesium will suggest a vegetarian diet.”

Most chemical, botanical and physical anthropology tests will be done at Deccan College. But the more sophisticated and expensive DNA and dating tests will be conducted in Japan. The Research Institute for Humanity and Nature, Kyoto and Maharshi Dayanand University, Rohtak, are collaborating with Deccan College under the aegis of the Archaeological Survey of India for the project.

The team also plans to carry out coring tests in lakes around the Farmana site to ascertain climatic conditions prevalent at the time of the Harappan civilization, and investigate whether the decline of the culture followed catastrophic climate change.

The burials found so far are expected to be from around 4509 BP (before present), or 2600-2200 BC. “There are three different levels of burials and at some places skeletal remains have been found one above the other. All the graves are rectangular ¿ different from other Harappan burials sites, which usually have oblong graves,” Prof Shinde said.

The site shows evidence of primary (full skeleton), secondary (only some bones) and symbolic burials, with most graves oriented northwest-southeast, though there are some with north-south and northeast-southwest orientations as well. The variations in burial orientation suggests different groups in the same community, Prof Shinde said. The differences in the numbers of pots as offerings suggest social and economic differences within the community. Also in evidence are significant signs of regional variations that contest the idea of a homogenous Harappan culture.
