Dmitry Konstantinovich Belyaev (Russian: Дми́трий Константи́нович Беля́ев, 17 July 1917 – 14 November 1985) was a Soviet scientist and academician. He was director of the Institute of Cytology and Genetics (IC&G) of the present-day Russian Academy of Sciences from 1959 to 1985. The changes to the foxes' coats as they became domesticated may have helped solve the biological riddle of how dogs developed coats different from wolves.
