An international team comprising researchers from Australia, Germany, the UK, India, and Canada have unearthe stone tools from a site in the Son River valley in Madhya Pradesh that depicts the continuous human occupation at the site since the last 80,000 years. This has put to rest on the decades-long argument that says supervolcanic eruption in the Indonesian island of Sumatra wiped out the ancient human species 74,000 years. The recent archaeological discovery provides strong evidence for the survival theory of the local population beyond the catastrophic eruption.
