Cooperation beats selfishness more often than scientists thought

A new study reveals that cooperation does not require close family ties or reputation, but rather opponent-specific responses, leading to the emergence of cooperative behavior. This finding challenges conventional evolutionary theory and has implications for the design of more collaborative artificial intelligence systems.
