Abstract: | 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 types of color vision, including
both trichromatic and dichromatic variants. In recent years, this polymorphism has been the target of an expanding range of
research efforts. As a result, researchers now reasonably understand the proximate biology underlying the polymorphisms, and
a number of ideas have emerged as to their evolution. Progress has also been made in illuminating how color vision capacities
may be related to the particular visual tasks that New World monkeys face. |
