Episode 314 - Ancient life and life in extreme places

February 18, 2019

From the bottom of the ocean, to the earliest days of the earth, life has managed to not just survive but thrive. We look at several cases which change our understanding of the earliest life on earth and just what that might mean for understanding life on this planet and beyond. From moving life fossilised in mud, to using isotopes to study metabolism and discovering whole new methods of getting food, life continues to astound researchers with its inventiveness.
