Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thought is a 1966 book by the American evolutionary biologist George C. Williams.Williams, in what is now considered a classic by evolutionary biologists, [1] outlines a gene-centered view of evolution, [2] disputes notions of evolutionary progress, and criticizes contemporary models of group selection, including the ...
George Christopher Williams (May 12, 1926 – September 8, 2010) was an American evolutionary biologist. [1] [2] [3]Williams was a professor of biology at the State University of New York at Stony Brook who was best known for his vigorous critique of group selection.
The view of the gene as the unit of selection was developed mainly in the works of Richard Dawkins, [10] [11] W. D. Hamilton, [12] [13] [14] Colin Pittendrigh [15] and George C. Williams. [16] It was popularized by Dawkins in his book The Selfish Gene (1976). [1] According to Williams' 1966 book Adaptation and Natural Selection,

[1] The group of biologists writing on a single unified (if somewhat broad) theme contrasts with Williams' earlier seminal 1966 book Adaptation and Natural Selection ...
Strength of natural selection plot as a function of age. The antagonistic pleiotropy hypothesis (APT) is a theory in evolutionary biology that suggests certain genes may confer beneficial effects early in an organism's life, enhancing reproductive success, while also causing detrimental effects later in life, contributing to the aging process.
George C. Williams in his book Adaptation and Natural Selection (1966) argues that the best way to explain altruism among animals is based on low-level (i.e., individual) selection as opposed to high-level group selection. Altruism is defined by some evolutionary biologists (e.g., R. Alexander, 1987; W. D. Hamilton, 1964) as behavior that is ...
