One of the mysteries of the English language finally explained.
Natural selection in favor of behavior by individuals that may decrease their chance of survival but increases that of their kin (who share a proportion of their genes).
- ‘A prerequisite for individuals accruing advantages through kin selection is interaction among relatives.’
- ‘But kin selection theory explains altruistic behaviour as a clever strategy devised by selfish genes as a way of increasing their representation in the gene-pool, at the expense of other genes.’
- ‘A predominant theory of social evolution is kin selection, which notes that it is advantageous for individuals to help their relatives because it increases the number of their shared genes in future generations.’
- ‘As one of the first models to explicitly examine immediate benefits of food sharing, we set the stage for more general or parsimonious explanations of sharing than kin selection and reciprocal altruism.’
- ‘In this case, reciprocal altruism and kin selection could explain the patterns observed, but these issues are far beyond the scope of this article.’
