Why people help distant kin

A new study suggests that socially enforced nepotism, a concept that expands the classic theory of kin selection, may explain why people are altruistic towards distant kin. The simulations show that helping distant relatives can increase one's reputation and lead to more help from others, improving social rules and enforcing them.

Robots learn to share, validating Hamilton's rule

Scientists used simple robots to test how altruism evolves over generations. The results matched Hamilton's rule, suggesting that helping relatives increases their chances of passing on genes. This study has implications for swarm robotics and the evolution of cooperation in nature.
