First genetic evidence of ongoing mating between 2 distinct species of guenon monkeys

A new study of guenon monkeys in Gombe National Park is the first to provide genetic evidence of ongoing mating between two distinct species. These monkeys have successfully been producing hybrid offspring for hundreds maybe even thousands of years. Prior studies have suggested that the different physical characteristics of these monkeys keeps them from interbreeding. So, if their faces don’t match, they shouldn’t be mating, right? Wrong, according to this latest evidence.
