Color vision is an evolutionary trait that provides primates with significant reproductive and survival value (Gomes, Pessoa, Suganuma, Tomaz, & Pessoa, 2002). However, the quantity and quality of color vision varies within and between species in the primate lineage. Primates are divided into four groups Apes, New World, Old World, and Prosimians. The New World primates are located in the rainforests of South America and surrounding areas, while the other groups of primates are distributed across Africa and Asia (Regan et al., 2005). The vast range of geographical locations inhabited by primates provide images of food requirements that vary dramatically based on environmental conditions.
Food requirement variations lead to color vision being an exponentially valuable trait in the evolutionary success of the primates based on its influences in foraging behavior. If an animal is unable to discriminate a piece of fruit from being ripe or unsafe to eat, they could potentially become sick, thus negatively impacting their chances of reproduction and survival (Regan et al., 2005).
Furthermore, color vision is not only beneficial in the survival of animals in the wild, but also the quality of life of animals in captivity. If an animal’s color vision is able to be determined, then enrichment, diet, and exhibit design can all be modified in a manner that provides the greatest mentally stimulating environment for the perception of that one individual. Ultimately, color vision is an…
