New Delhi, Sept. 3 -- Summary Evolution scientist Francis Thackeray proposes a groundbreaking hypothesis linking supernova remnants to global cooling and human evolution.

He suggests that cosmic rays from an exploding star may have caused climate changes between 3 million and 2.6 million years ago, impacting the evolution of hominins.

This theory challenges previous assumptions about ocean currents being the primary cause of ancient global cooling.

What's the link between an exploding star, climate change and human evolution? Francis Thackeray, who has researched ancient environments and fossils for many years, sets out his ideas about what happened in the distant past - with enormous consequences.
