Question

Quizplus · Accepted Answer

Kin selection refers to the selection of traits that promote the survival and reproduction of an individual's relatives, even at a cost to the individual's own survival and reproduction. This can result in the evolution of altruistic behaviors directed towards close relatives, as individuals who possess these traits are more likely to pass them on to their relatives and ultimately increase the representation of their genes in future generations. Kin selection is an extension of the broader theory of natural selection, which posits that traits that increase an individual's reproductive success are more likely to be passed on to future generations.
