Indus Peoples to Australia in 2200 BCE?

However incredible this may seem, there now seems to be good genetic and material evidence that sailors from India arrived in Australia from either Sindh or South India at the height of the ancient Indus civilization. They brought with them some technologies and a type of dog that forever changed Aborigine culture. As principal scientist Irina Pulgach at the Max Planck Institute writes, "Their findings suggest substantial gene flow from India to Australia 4,230 years ago. i.e. during the Holocene and well before European contact. Interestingly this date also coincides with many changes in the archaeological record of Australia, which include a sudden change in plant processing and stone tool technologies, with microliths appearing for the first time, and the first appearance of the dingo in the fossil record. Since we detect inflow of genes from India into Australia at around the same time, it is likely that these changes were related to this migration.”
