Traditional life history theory ignores trade-offs due to social interactions, yet social systems expand the set of possible trade-offs affecting a species evolution—by introducing asymmetric ...

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.

The dominant evolutionary theory for Earth's most successful creatures, and a proposed influence on human altruism, is under attack. For decades, selflessness -- as exhibited in eusocial insect ...

In an article to be published in the January issue of BioScience, two philosophers tackle one of the most divisive arguments in modern biology: the value of the theory of "kin selection." Kin ...

Several models have been proposed to explain the evolution of leks, both in terms of direct or indirect fitness benefits, and in survival. According to kin selection theory, male skewed reproductive ...
