Kin selection and local competition in a heterogeneous community.

摘要: When should an individual be willing to pay a cost in order help or harm another its community? Kin selection suggests that relatives each other, while competition for limited resources may select harming behaviour against neighbours. This study considers social interactions between two individuals. For actions influencing non-dispersing reproduction, condition is derived favour helping harming, as function of the actor's relationship rest community and recipient. Where individuals differ their relatedness community, which less related will more helpful. Two with given other helpful they jointly become community. The implications these results are explored through example involving from ancestral groups. directional selective effects depend on extent assortative rather than random, distribution opportunities harming.
