COLLATERAL ALTRUISM. “Why, then, has eusociality been so rare? The answer is that it requires collateral altruism, which is behavior benefiting others at the cost of the lifetime production of offspring by the altruist. The existence of collateral altruism is one of the perennial problems of evolutionary biology. Given its genetic consequences, how can programmed sacrifices to collaterally related group members arise by natural selection?” https://lnkd.in/drgWvGT View in LinkedIn

SO ENDS this first of two weekends on a wonderful EO Wilson article about the evolution of eusocial insect societies. Insect societies are far older than human societies and very diverse in structure. How these groups are organized, and what ramifications they have, may shed some light on future human societies, after our initial rather blundering experiments on the subject. View in LinkedIn
