UPSC Civil Services Model Paper 6

The year 2020 marks 100 years of discovery of Indus Valley Civilisation , and a new study has shown that dairy products were being produced by the Harappans as far back as 2500 BCE .
Hence statement 1 is correct.
By analysing residues on ancient pots, researchers show the earliest direct evidence of dairy product processing, thus throwing fresh light on the rural economy of the civilisation.
“When we talk about Harappans, we always refer to the metropolitan cities and the big towns. But we have no idea of the parallel economy —
agro-pastoral or rural . We know they had great urban planning , trading systems , jewellery making. But we don't have any idea how the common masters were living during the Harappan times, their lifestyle and how they were contributing in the larger network,” explains Prabodh Shirvalkar, from the Department of Ancient Indian History, Culture and Archaeology at the Deccan College Postgraduate and Research Institute, Pune.
The team used molecular analysis techniques to study the residues from ancient pottery.

The study also shows which type of animals were being used for dairy production.
They studied the tooth enamel from fossils of cattle, water buffalo, goat and sheep found in the area.
