New research shows that family ties and traits such as manipulation, sacrifice and selflessness are just as key to survival in parasitic organisms as they are in cognitive species like humans. In ...

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 ...

Last week Sarah Jane explained the evolutionary advantage of helping out family members, an idea known as kin selection. While the benefits are clear, we don't know how kin selection initially evolves ...

In 1975 Harvard biologist E. O. Wilson published Sociobiology, perhaps the most powerful refinement of evolutionary theory since On the Origin of Species. Darwin’s theory of natural selection ...

This is a preview. Log in through your library . Abstract Social Hymenoptera have played a leading role in development and testing of kin selection theory. Inclusive fitness models, following from ...

We present here a stochastic two-locus, two-habitat model for the evolution of migration with local adaptation and kin selection. One locus determines the migration rate while the other causes local ...

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 ...

New research by Texas A&M University biologist Dr. Charles Criscione and collaborators in Canada shows that family ties and traits such as manipulation, sacrifice and selflessness are just as key to ...

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.
