Sexual selection: Difference between revisions

Other kinds of selection are for example ''environmental'' or ''asexual selection'', referring to selection done by the environment or ecology e.g. due to famines, disease or natural death, and everything else that is not sexual. Further, there is ''kin selection'', referring to how the individual influences the [[reproductive success|reproductive success]] of his relatives in which the individual's genes have interest in due to the genetic similarity of relatives. E.g. altruism within families may be kin selected. Lastly, there is ''group selection'', i.e. selection based on how the individual affects the survival and reproduction of entire groups. If a mutation results in better group survival, then that mutation may stick around because it may also (slightly) increase the individual's reproductive success. The effects of group selection are believed to be small compared to kin, sexual and environmental selection.
