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. Kin selection can lead to the evolution of altruistic behaviour.
Kin selection, a type of natural selection that considers the role relatives play when evaluating the genetic fitness of a given individual. It is based on the concept of inclusive fitness, which is made up of individual survival and reproduction (direct fitness) and any impact that an individual.
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?
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.
Jan 1, 2021 · Kin selection, Hamilton’s rule, and inclusive fitness are three of the most widely known concepts originating from Hamilton’s work, and they are at times used with much overlap in the literature. Here a separation is maintained between these notions, each with its own meaning.
Kin selection theory is a formulation of natural selection theory that is particularly suitable for understanding cases of reproductive self-sacrifice. For example, sterile workers in insect societies help the queen to reproduce by rearing her offspring.
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.
Kin selection is best understood by taking a gene's eye view (which, we should be reminded, is not a commitment to invoking selection at any particular level), though it is most accurately described as a form of group selection. Although mathematically it is possible – and even sometimes heuristically invaluable – to make all fitness ...
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).
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 ...
