Fisher, Michael H. (2018), An Environmental History of India: From Earliest Times to the Twenty-First Century, Cambridge University Press, ISBN978-1-107-11162-2 Quote: "page 33: "The earliest discovered instance in India of well-established, settled agricultural society is at Mehrgarh in the hills between the Bolan Pass and the Indus plain (today in Pakistan) (see Map 3.1). From as early as 7000 BC, communities there started investing increased labor in preparing the land and selecting, planting, tending, and harvesting particular grain-producing plants. They also domesticated animals, including sheep, goats, pigs, and oxen (both humped zebu [Bos indicus] and unhumped [Bos taurus]). Castrating oxen, for instance, turned them from mainly meat sources into domesticated draft-animals as well."
Dyson, Tim (2018), A Population History of India: From the First Modern People to the Present Day, Oxford University Press, ISBN978-0-19-882905-8, Quote: "(p 29) "The subcontinent's people were hunter-gatherers for many millennia. There were very few of them. Indeed, 10,000 years ago there may only have been a couple of hundred thousand people, living in small, often isolated groups, the descendants of various 'modern' human incomers. Then, perhaps linked to events in Mesopotamia, about 8,500 years ago agriculture emerged in Baluchistan."
