If transmission occurs before selection in the life cycle of a host-associated bacterial species, gene mobility will also have a substantial effect on the selection term. This will primarily be by ...

I promised I'd go over the recent PNAS paper, Group selection and kin selection: Two concepts but one process. This is one of those articles where most of the heavy lifting is in the technical ...

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 ...

Natural selection favors people who help close kin at their own expense: It can increase the odds the family’s genes are passed to future generations. But why assist distant relatives? Mathematical ...

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 ...
