    " Kin selection is the evolutionary mechanism that selects for those behaviors that increase the inclusive fitness of the donor. A well known example of kin selection in operation is the study of alarm calls in squirrels by Paul Sherman (1977. Nepotism and the evolution of alarm calls. Science 197:1246-1253). In this study, Sherman studied the likelihood of males (who do not nest near genetic relatives) and females (who do nest near genetic relatives) to give alarm calls that warn others of predators while placing caller at a greater risk of attack. It turns out that males are less likely to give such calls than females, thus supporting the kin selection hypothesis."
