Hybridization is widely recognized as promoting both species and phenotypic diversity. However, its role in mammalian evolution is rarely examined. We report historical hybridization among a group of snub-nosed monkeys (
) that resulted in the origin of a hybrid species. The geographically isolated gray snub-nosed monkey
shows a stable mixed genomic ancestry derived from the golden snub-nosed monkey (
) and the ancestor of black-white (
) and black snub-nosed monkeys (
). We further identified key genes derived from the parental lineages, respectively, that may have contributed to the mosaic coat coloration of
, which likely promoted premating reproductive isolation of the hybrid from parental lineages. Our study highlights the underappreciated role of hybridization in generating species and phenotypic diversity in mammals.
