Speaker: Tianchen He
Animal life only emerged after the oxygen content of the atmosphere and ocean increased dramatically roughly 700 million years age. However, the exact triggers that allow this fundamental change in life on Earth are still not clear. The talk will provide insights into the story of early animal evolution and resolve the plausible causes and consequences of the unprecedented Cambrian explosion.
Note: When you book for this talk you also book for the other talk in this session - Mechanisms for keeping the Earth habitable.
