Abstract Fossil ceboid evidence is reviewed with reference to the origins and affinities of the New World monkeys. This evidence indicates that the ceboids evolved from a North American primate of omomyid-like form. The events of continental drift apparently had little to do with the origin and dispersion of the New World monkeys and direct ...

Trichromatic colour vision in New World monkeys
Nature, 1996Trichromatic colour vision depends on the presence of three types of cone photopigment. Trichromacy is the norm for all Old World monkeys, apes and humans, but in several genera of New World monkeys, colour vision is strikingly polymorphic. The difference in colour vision between these New and Old World primates results form differing arrangements of ...

The visual worlds of most primates are rich with potential color signals, and many representatives of the order have evolved the biological mechanisms that allow them to exploit these sources of information. Unlike the catarrhines, platyrrhines typically have sex-linked polymorphic color vision that provides individuals with any of several distinct ...

Arboreal locomotion in small New-World monkeys
Zeitschrift für Morphologie und Anthropologie, 2002The postural and locomotor activity and its relation to substrates was observed in 3 Saguinus oedipus, and 3 Saimiri sciureus for comparison, during a period of 10 h for each individual. The animals moved freely in cages of 3.40 m x 3.40 m x 2.40 m (height) on rather diverse substrates.

The Origin of the New World monkeys
1993Abstract The New World or platyrrhine, monkeys are found today in the tropical regions of both Central and South America. Their fossil record extends back approximately 26 million years to the Late Oligocene Deseadan Beds of Bolivia (Branisella boliviana) (MacFadden 1990), and this poses a mystery.

Evolution of feeding niches in new world monkeys
American Journal of Physical Anthropology, 1992AbstractThe adaptive radiation of modern New World monkeys unfolded as the major lineages diversified within different dietary‐adaptive zones predicated upon a fundamentally frugivorous habit. The broad outlines of this pattern can be seen in the fossil record, beginning in the early Miocene. Cebids are obligate frugivorous predators.
