Wright is perhaps best known for his concept of genetic drift, called the Sewall Wright effect, which says that when small populations of a species are isolated, out of pure chance the few individuals who carry certain relatively rare genes may fail to transmit them. He then married Louise Lane Williams, a genetics teacher at Smith College and in 1921 they had three kids; Richard, Robert, and Elizabeth Quincy Wright. Nevertheless, it is not clear that his “shifting balance” mechanism actually operates in nature (Coyne et al. Sewall Green Wright was born to parents Philip Green Wright and Elizabeth Quincy Sewall Wright (some sources cite the pair as a pair of first cousins, ironically due to Wright's future research and inbreeding) in Melrose, Massachusetts.

Sewall Green Wright (December 21, 1889 – March 3, 1988) was an American geneticist known for his influential work on evolutionary theory and also for his work on path analysis. As Fisher argued, a changing environment allows continual evolution across the vast space of possible genotypes (see Provine 1986 for the correspondence between Fisher and Wright on these issues). In 1950 he had given the Galton lecture at University College, London and applied his methods for the path of coefficients to problems of population structure from situations such as: random mating and inbreeding, statistical properties of populations, the inbreeding coefficient F, hierarchic structure, natural populations, the island model of structure, isolation by distance, population structure in evolution, ecologic opportunity, and evolution in general.

In 1912 he graduated with a Master's degree and accepted an assistantship at the Harvard Bussey Institution after Ernest "William Ernest" William Castle interviewed him in his last year after he put his input about the size and coat-color experiments on the guinea pigs. He found a new statistical approach called "Path Analysis." B. S. Haldane, which was a major step in the development of the modern synthesis combining genetics with evolution. Within the five years at the College, he strayed away from chemistry and instead into mathematics. The roles of local fitness peaks and gene flow in adaptive evolution remain major open questions in evolutionary biology, nearly a century after Wright first raised the issue. They carried out breeding experiments like previous geneticists, but they also did something new: they built sophisticated mathematical models of evolution. On the one hand, most biologists came to the reality of evolution — that living species shared a common ancestry and had been transformed over time. After the rediscovery of Mendel’s work in 1900, bitter disputes erupted between the first geneticists and the biometricians who studied quantitative traits. He decided to go to University of Chicago in 1926 and remained until his retirement in 1955. Genetics of natural populations. B. S.
