So in hindsight, it looks like the British archaeologist and director general of the Archaeological Survey of India between 1944 and 1948, Sir Robert… - Tony Joseph

So here is a question: if you were to identify a single person who embodies us Indians the best, who do you think it should be? Ideally, it should be a tribal woman because she is most likely to be carrying the deepest-rooted and widest-spread mtDNA lineage in India today, M2. In a genetic sense, she would represent all of our history, with very little left out. She shares the most with the largest number of Indians, no matter where in the social ladder they stand, what language they speak and which region they inhabit because we all migrants and we are all mixed. And she was here from the beginning. And she was most likely also at Mohenjo-daro as the 'dancing girl' (the image on the cover) about 4500 years ago, during the period that most shaped us as we are today.

The millennium or so that followed the dimming of the Harappan Civilization would have been the most tumultuous and turbulent period in the history of the modern human in south Asia. But we have very little record of this and hence very little understanding of it. Look at all that happened: a long-standing civilization, the largest of its kind at the time, fell apart due to the ravages of a long drought, and its most visible symbols of power and prestige slowly disappeared even as urbanism itself did; people migrated to the east and the south in search of a new life; a new set of migrants came in from the north-west, bringing new languages and a different culture that put emphasis on sacrificial rituals and prioritized pastoralism and cattle breeding over urban settlements; another set of migrants came in from the north-east, bringing new languages, new domesticated plants and perhaps wetland farming techniques and a new variety of rice... and thus the pot of Indian culture was put on the boil. Four thousand years later, it is still simmering, with new ingredients getting added once in a while, from the Jews to the Syrians to the Parsis.

The residents of Mehrgarh who raised the first mud-brick homes of two or three rooms may not have realized it then, but they were laying the foundation for the first efflorescence of civilization in South Asia, called the Harappan Civilization, or the Indus Valley Civilization. It took about 4500 years or over 150 generations, for those humble mud-brick abodes to turn into the urban structures of a Harappa or a Mohenjo-daro or a Dholavira and there must have been many twists and turns along the way. But once agriculture took root, and modern humans started creating a surplus that they could save and invest, the wheels of history started spinning fast - which would, of course, lead to the invention of the wheel itself!
