Cooperative Interactions

The podcast explores cooperative interactions in living systems, using game theory to illustrate the benefits of cooperation over conflict. It discusses cooperation at three levels: single cells in the rumen of a cow, cooperation within cells, and cooperation among organs in the digestive system. The podcast emphasizes that cooperation leads to mutual benefits, while competition can be detrimental.
