They performed a comparative study of representative species from all three cebid genera, unveiling the evolutionary history of genetic modifications that allowed the rise of the distinctive neurobiology of capuchins and squirrel monkeys.īyrne et al. ( 2) sequenced a high-quality genome of the robust capuchin Sapajus apella. Up to now, two of the three genera of extant cebids have publicly available genomes: the squirrel monkey Saimiri boliviensis and the gracile capuchin Cebus imitator. Although research on capuchin monkey behavior is extensive, the genetic basis underpinning the development of advanced cognition of cebids remains unknown. ![]() Capuchins are characterized by advanced cognitive abilities and sensorimotor intelligence, which is particularly true of the robust capuchin monkeys (genus Sapajus), who frequently exhibit imaginative use of tools. Cebids present one of the largest encephalization quotients found in primates. Living platyrrhines comprise five evolutionary offshoots (families) with diverse morphologies and ecologies: the seed-eating sakis and uakaris and the titi monkeys (Pitheciidae), the large-sized Atelidae with their prehensile tails, the tiny and brightly colored marmosets and tamarins (Callithrichidae), the nocturnal owl monkey (Aotidae), and the Cebidae (squirrel monkeys and capuchins) ( 1). They arrived in South America ∼40 Ma, probably by transoceanic dispersal, when the continent had no connections with other landmasses. Neotropical primates(infraorder Platyrrhini) are among the most species-rich primate lineages. ![]()
