The first urban settlement of the Early Harappan phase was Mehrgarh (in present-day Baluchistan). The people in Mehrgarh used stone tools in the initial. There is no evidence of the use of pottery in this settlement. In the second phase of urban development, there was some advancement in stone tools and pottery began to be used. As the settlement grew, the size of the villages also expanded. The houses started becoming bigger. Agriculture also began to be practiced on a large scale. Similar Early Harappan settlements have also been discovered in Mundigak in Afghanistan and in the Cholistan desert region in the Ghaggar-Hakra valley.
