Gene-centered view of evolution selection was developed mainly in the works of Richard Dawkins, W. D. Hamilton, Colin Pittendrigh and George C. Williams. It was mainly popularized and expanded by Dawkins in his book "The Selfish Gene" (1976). According to Williams' 1966 book "Adaptation and Natural Selection", Williams argued that "[t]he natural selection of phenotypes cannot in itself produce cumulative change, because phenotypes are extremely temporary manifestations." Each phenotype is the unique product of the interaction between genome and environment. It does not matter how fit and fertile a phenotype is, it will eventually be destroyed and will never be duplicated. Since 1954, it
The Selfish Gene by limiting family size to conform with available resources, thus avoiding extinction as predicted under the Malthusian model of population growth. Dawkins says that his "purpose" in writing "The Selfish Gene" is "to examine the biology of selfishness and altruism." He does this by supporting the claim that "gene selfishness will usually give rise to selfishness in individual behaviour. However, as we shall see, there are special circumstances in which a gene can achieve its own selfish goals best by fostering a limited form of altruism at the level of individual animals." Gene selection provides one explanation for kin selection
