Twenty three nonmetric traits of 248 Japanese monkey skulls from 5 regions were investigated, and 22 traits showed significant geographic variation in frequency.Fifteen traits were compared between two populations which originated in the same lowland area of Yakushima, but developed in different environments: the wild population of Yakushima and the second and third generations of the provisioned troop in Ohirayama Park, where the climate is much colder. Twelve traits did not differ in frequency between the two populations. This stability of these nonmetric traits despite environmental change suggests their high heritability.
