Owl Monkeys: Biology, Adaptive Radiation, and Behavioral Ecology of the Only Nocturnal Primate in the Americas (Developments in Primatology: Progress and Prospects) . One hypothesis about the origins of adaptive radiation is that hybridization between species is necessary to trigger diversification, because lineages may be limited in their ability to respond to ecological opportunity by a lack of genetic variation (7, 8).Indeed, extensive histories of hybridization have been documented in many classic and spectacular radiations (9-13).
