Research Abstract

Kin selection is one of the theories that explains the evolution of altruism, which means a behavior that benefits other individuals in terms of survival or reproductive success. I have extended this theory, which originally concentrated on kinship between two individuals, to incorporate interactions of more than two individuals. For that purpose, I have generalized genetic relatedness for two individuals to a higher order one which represents genetic similarity of three individuals or more. As an application, I have studied quorum sensing, a form of microbial communication by chemical signals. I have shown that quorum sensing evolves under the existence of high genetic relatedness between individuals.
