Inclusive fitness example biology
Hamilton showed mathematically that, because other members of a population may share one's genes, a gene can also increase its evolutionary success by indirectly promoting the reproduction and survival of other individuals who also carry that gene. This is variously called "kin theory", "kin selection theory" or "inclusive fitness theory". The most obvious category of such individuals is close genetic relatives, and where these are concerned, the application of inclusive fitness theor… WebDec 1, 2016 · Inclusive fitness theory is a cornerstone of modern evolutionary biology, yet critics contend it is not general but subject to serious limitations, and is ripe for replacement, for example by ...

WebOct 8, 2024 · Photo by Marcel Brekelmans. Loosely defined, fitness is the probability of raising more offspring in the future (or eventually). That is in line with the common but fallacious notion that the primary goal of all living beings is to survive and reproduce. Evolutionary success is indeed measured in the number of offspring or gene copies an ... WebJan 1, 2024 · Inclusive fitness relies in part on kin recognition and relatedness coefficients, which reflect the probability of sharing a given gene or allele between two relatives. For example, first-, second-, and third-order relatives have relatedness coefficients of 0.5, 0.25, and 0.125, respectively. Hamilton’s rule (see Eq.
WebMar 23, 2015 · Abstract. The evolution of sterile worker castes in eusocial insects was a major problem in evolutionary theory until Hamilton developed a method called inclusive fitness. He used it to show that sterile castes could evolve via kin selection, in which a gene for altruistic sterility is favored when the altruism sufficiently benefits relatives ...

Inclusive fitness is a fundamental concept in evolutionary biology, but some critics argue that it has limitations and should be replaced by multilevel selection theory.
