Vavilov center
A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties. Centers of origin were first identified in 1924 by Nikolai Vavilov. Vavilov posited that the center of origin for a species or genus is the same as its center of diversity, the geographic area where it has the highest genetic diversity, but this equivalence has been disputed by later scholars.
