Inclusive fitness vs kin selection
WebDec 17, 2008 · INTRODUCTION. Kin-selection theory predicts that animals increase their fitness by allocating more cooperation to kin than to non-kin. Hamilton (1964) showed that altruism (or, conversely, reduced aggression) is favored when rb − c > 0, where r is the genetic relatedness between two individuals, b is the (genetic) fitness benefit to the … WebApr 12, 2024 · Kin and multilevel selection provide explanations for the existence of altruism based on traits or processes that enhance the inclusive fitness of an altruist individual. Kin selection is often based on individual-level traits, such as the ability to recognize other altruists, whereas multilevel selection requires a metapopulation structure and dispersal …

WebJul 1, 2012 · We find that with sex‐limited selection, direct and kin selection are equally effective when queens are singly mated, and we expect no difference in rates of molecular evolution of queen versus worker‐expressed loci. This result is in sharp contrast to the situation in which fitness traits are not sex limited (Linksvayer and Wade 2009). In ... WebThe existence of kin selecting behaviors, selectively favoring relatives with assistance, is well established in other members of the animal kingdom, but the mental aspects of kin selection are relatively unknown. Some claim that no clear evidence exists for processes enhancing inclusive fitness in humans (e.g., Batson, 1997). However,

WebJun 3, 2003 · Kin Selection and Inclusive Fitness The basic idea of kin selection is simple. Imagine a gene which causes its bearer to behave altruistically towards other organisms, e.g. by sharing food with them. Organisms without the gene are selfish—they keep all their food for themselves, and sometimes get handouts from the altruists. WebMay 14, 2024 · 18.8: Kin Selection. In the discussion of natural selection, the emphasis was on how natural selection works on individuals to favor the more fit and disfavor the less fit in a population. The emphasis was on the survival (mortality selection), mating success (sexual selection), or family size (fecundity selection) of individuals.
