A furor has broken out among biologists over ant specialist E.O. Wilson’s latest attack on a concept used to explain the origins of self-sacrifice in the dog-eat-dog world of evolution. The debate ...

Researchers have used several different ways of testing Hamilton's rule, the core mathematical formula of kin selection, as an explanation for the evolution of much altruistic behavior in animals.

A battle is being waged over kin and kind: Did cooperation evolve in humans and other animals because it helped relatives? Or because it promoted group living? A school of thought known as inclusive ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 78, No. 7, [Part 2: Biological Sciences] (Jul., 1981), pp. 4440-4443 (4 pages) The altruistic-gene theory of kin ...

Understanding the maintenance of cooperation is of fundamental importance in evolutionary biology. Kin selection is a powerful mechanism that explains altruism (Hamilton, 1964), the principle being ...
