Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thought is a 1966 book by the AmericanGeorge C. Williams on evolutionary biology. In it, Williams outlines a genecentric view of evolution, disparaging group selection and progress. This viewpoint was subsequently adopted by the scientific community in the Williams revolution.

Naturalselection works on the whole individual, but only the heritable component of a trait will be passed on to the offspring, with the result that favorable, heritable traits become more common in the next generation.
Naturalselection is one of the cornerstones of modern biology.
A strong selective sweep results in a region of the genome where the positively selected haplotype (the allele and its neighbours) are essentially the only ones that exist in the population.
