Sewall Green Wright spent his lifetime in the United States. He was born December 21, 1889 in Melrose, Massachusetts. He died in Madison, Wisconsin on March 3, 1988 at 99 years old!
Wright is origin for the term of Genetic drift which is "the random events that change the frequency of various alleles in a population." (NNDB) In his life he published multiple works which included: Systems of Mating and Other Papers (1949), Genetic and Biometric Foundations (1968), Evolution and the Genetics of Populations (1968-78), Experimental Results and Evolutionary Deductions (1977), Variability Within and Among Natural Populations (1978), Evolution: Selected Papers (1986). He utilized mathematics to describe the movements of genes during evolution, proving how natural selection, mutation, and various evolutionary forces change the alleles and genotypes. In his paper Evolution in Mendelian Populations from 1931 he explained "shifting balance" which says that the population of a species is dependent upon various evolutionary forces, such as isolation, geographic locations of groups, and that this can result in overall further "upgrade" the entirety of a species. While at the Department of Agriculture Wright worked on his inbreeding coefficient which is an algorithm that determines effects of inbreeding with heterozygosity.
Wright's work does not hold much effect on the modern theory of evolution. His idea of the shifting balance was highly disputed by Ronald Fisher, whom held an opposing view. In a way, Wright's work spurred others to aid in developing theories of evolution by taking such ardent views and theories on the development of species. Within today's society he is not a well known person but many people unknowingly agree with his ideas, they just are unaware that Wright publicized
