  1. Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. [1] Kin selection can lead to the evolution of altruistic behaviour.

  2. Kin selection occurs when an animal engages in self-sacrificial behaviour that benefits the genetic fitness of its relatives. The theory of kin selection is one of the foundations of the modern study of social behaviour.

  3. May 14, 2022 · Natural selection working at the level of the family rather than the individual is called kin selection. How good is the evidence for kin selection? Does the behavior of the mother bird really increase her chances of being killed?

  4. Jan 1, 2021 · In its modern form, kin selection is composed of a robust general theoretical framework (regression models) and a set of more practical modelling tools (weak selection models). Kin selection has been the source of considerable debate, and much of this debate has focused on the tension between kin selection and group selection.

  5. Kinship is a key element of most contemporary field studies of social behavior in animals. Kin selection requires and is based on genetic relatedness between the donor and the recipient of the altruistic act. Kin selection is the dominant explanation for the evolution of aid-giving behavior.

  6. Jan 1, 2020 · The term first coined by Maynard Smith in 1964, kin selection is an extension of natural selection that incorporates how indirect sources of reproductive success (fitness of relatives) affect an organism’s actions to optimize its own fitness.

  7. Mar 23, 2011 · Hamilton 1 described a selective process in which individuals affect kin (kin selection), developed a novel modelling strategy for it (inclusive fitness), and derived a rule to describe it ...

  8. Aug 26, 2010 · For the past four decades kin selection theory, based on the concept of inclusive fitness, has been the major theoretical attempt to explain the evolution of eusociality. Here we show the ...

  9. Dec 23, 2002 · Kin selection is a part of natural selection. Selection normally favors a gene if it increases reproduction, because the offspring share copies of that gene, but a gene can also be favored if it aids other relatives, who also share copies.

  10. Mar 30, 2015 · An encyclopedic, well-illustrated survey of social systems in nature, first published in 1975. Endorsed kin selection and sparked controversy through applying kin selection and similar ideas to social evolution in humans. The author has since become a critic of kin selection theory (see Controversy).
