It has really only been since the 1980s that a more comprehensive picture of the wide and deep roots of Indus civilization in the larger Sindh and Balochistan region have become apparent. Mehrgarh did not spring out of nowhere but was embedded in a region where fishing, shell collecting, flint mining and other crafts were present and flourishing at different times.
The authors write that "the discovery of a knapped stone assemblage with microlithic backed tools and geometrics represents a groundbreaking point for the prehistory of Punjab. It opens new research perspectives in a promising territory that had never been explored before, where surveys are undoubtedly to be continued in the future because of its great potential."
This paper reviews the work done since the early 1970s east of Karachi along the Makran coast, containing what were once extensive mangrove areas (where salt and fresh water meet to create unique habitats).
Another important summary paper by Paolo Biagi reprises all the discoveries made by Italian teams in Sindh and Balochistan that have upended our understanding of pre and neighbouring areas to the Indus civilization.
The Mesolithic Settlement of Sindh (Pakistan): New Evidence from the Khadeji River Course, an article by Paolo Biagi is another piece of the puzzle of habitation in the Indus delta long before the ancient Indus civilization.
A very important recent exposition of one of the most important underlying elements – used to make fire, crucial items like weights and much else – of ancient Indus civilization and its connection to, in particular the Rohri Hills.
Preliminary results from recent surveys along the little explored coast of Sindh and Balochistan, where the evidence of ancient human habitation along a one-time mangrove coast keeps growing.
The research carried out in Sindh during the last forty years, and the study of the chipped stone assemblages stored in Karachi University collections, show that Late (Upper) Palaeolithic [50,000-10,000 years ago] complexes are known from at least five regions of Sindh. Most sites are located close to good quality raw material outcrops and freshwater sources.
In this 2004 article from the quarterly publication Sindh Watch, Paolo Biagi synthesizes the evidence of female clay figurines from Bronze Age sites in the Indus Valley to highlight the social and cultural roles of women in that society. He draws on earlier evidence from the neolithic site of Mehrgarh, in Balochistan, as well as that from mature Harappan sites like Mohenjodaro and Harappa. Based on this analysis he offers the insights into the role of women as depicted in the figurines.
The research carried out in the Indian Subcontinent, Central Asia, Iran, and the Arabian Peninsula has improved our knowledge of the Middle Paleolithic in the regions. However, the southeasternmost distribution of the Levallois Mousterian is still poorly defined.
