During the 1930s and 1940s population genetics became integrated with other biological fields, resulting in a widely applicable theory of evolution that encompassed much of biology—the modern synthesis.
Tijekom 1930-ih i 1940-ih populacijska genetika integrirana je s ostalim poljima biologije što je rezultiralo široko prihvaćenom teorijom evolucije koja je obuhvatila veliki dio biologije—modernom evolucijskom sintezom.
