摘要

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 (Rhinopithecus) that resulted in the origin of a hybrid species. The geographically isolated gray snub-nosed monkey Rhinopithecus brelichi shows a stable mixed genomic ancestry derived from the golden snub-nosed monkey (Rhinopithecus roxellana) and the ancestor of black-white (Rhinopithecus bieti) and black snub-nosed monkeys (Rhinopithecus strykeri). We further identified key genes derived from the parental lineages, respectively, that may have contributed to the mosaic coat coloration of R. brelichi, 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.
