Under the supposed condition that pollen grains compete with each other over fertilization success in a pistil (Iritani 2024 , Kobayashi, 2024a ), kin selection favours cooperative traits when pollen grains on a flower stigma … WebHamilton’s inclusive fitness theory, as well as kin selection, seemed to many biologists to reconcile the conflict between natural selection, in which “selfish” genes perpetuate their …
WebKin selection, a recognized evolutionary process amongst living organisms, was first recognized as an important mechanism in evolutionary theory by Hamilton (1964). The example of siderophore production and the development of cheaters raises problems concerning the survival of the non-cheating organism. Kin selection is the evolutionary strategy that favours the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. Kin altruism can look like altruistic behaviour whose evolution is driven by kin selection.
