Sewall Wright was born on December 21, 1889, in Melrose, Massachusetts, to Philip Green Wright and Elizabeth Quincy Sewall Wright. He developed an interest in science and mathematics at an early age, which was encouraged by his parents. Wright attended Lombard College in Galesburg, Illinois, where he earned his Bachelor's degree in 1911. He then moved to the University of Illinois, where he earned his Master's degree in 1912 and his Ph.D. in 1915, working under the guidance of William Ernest Castle, a prominent geneticist. During his time at the University of Illinois, Wright was also influenced by the work of Thomas Hunt Morgan, a renowned geneticist who discovered the role of chromosomes in heredity.

Wright's most notable contributions to population genetics include the development of the shifting balance theory, which describes the process by which genetic variation is maintained within a population. He also worked on the concept of genetic drift, which refers to the random change in the frequency of a gene or genetic trait within a population over time. Wright's work on these topics was influenced by his collaborations with other prominent scientists, including Ronald Fisher, who is known for his work on statistical analysis, and Theodosius Dobzhansky, who made significant contributions to the field of evolutionary biology. Wright's research also built upon the foundational work of Charles Darwin, whose theory of evolution by natural selection laid the groundwork for modern genetics. Additionally, Wright was influenced by the work of Gregor Mendel, who is considered the father of modern genetics, and by the statistical methods developed by Karl Pearson, a prominent statistician.

Wright's influence on modern genetics is undeniable. His work on the shifting balance theory and genetic drift has been widely cited and built upon by other scientists. For example, the work of Motoo Kimura, a Japanese geneticist, on the neutral theory of molecular evolution was influenced by Wright's concept of genetic drift. Wright's collaborations with other scientists, including Leonard Darwin, the son of Charles Darwin, also helped to establish him as a leading figure in the field of genetics. The development of modern genetic tools, such as those used in genome-wide association studies, has also been influenced by Wright's work on population genetics. Furthermore, Wright's research has been applied in fields such as agriculture, where it has been used to improve crop yields and disease resistance, and in medicine, where it has been used to understand the genetic basis of human disease.

Sewall Wright passed away on March 3, 1988, at the age of 98, leaving behind a legacy of significant contributions to the field of genetics. His work continues to influence modern genetics, and his collaborations with other prominent scientists have had a lasting impact on the study of evolution and genetics. Wright's research has also been recognized by numerous awards, including the Thomas Hunt Morgan Medal, which is awarded by the Genetics Society of America. Today, Wright's work remains an essential part of the foundation of modern genetics, and his influence can be seen in the work of scientists such as David Reich, who has used genetic data to study human evolution, and Svante Pääbo, who has used genetic data to study the evolution of humans and other organisms.
