Ep 3. Why is life so diverse?

In the first two episodes of this season, we’ve examined how fundamental rules like scaling laws constrain evolution for all forms of life. But if everything is bound to these core rules, then why do we see exceptions? In this episode, Abha and Chris get into the incredible diversity of plants and animals on this planet, where that diversity comes from, and if it’s possible to make forecasts about the biosphere, just like we do for the weather. And, what happens when biodiversity is threatened?
