Wildfires Changed Human Evolution - Is It Happening Again?
Summary
This episode explores how environmental fluctuations and wildfires in East Africa 1.75 million years ago may have driven human evolution, tool use, and fire control. Hosts Penny Sarchet and Owen Hooper discuss new research with guests Michael LePage and Sam Wong, linking ancient climate variability to modern challenges. The conversation shifts to contemporary impacts, including rapid climate change, forced migration, and the limited ability of wildlife to adapt to intensifying wildfires.
