Episode 320 - Extinction events and their causes

April 1, 2019

Life has been around on earth for a long time, but there have been many extinction events that have wiped out large numbers of species. This week we find out how scientists peel back the layers of rock to uncover what caused these extinction events. Plus we find out about current extinction events and what we can learn from the past to protect species today.
