Decent Essays

Organisms possess several types of color vision depending on what wavelengths they are sensitive to. Humans are trichromatic, because their vision is formed by long, middle and short wavelength sensitive cones (Carroll, et.al, 2009). Depending on the environment, primates will have different variations of color vision. (Melin, et.al, 2017). Routine trichromacy and polymorphic trichromacy both track different food sources. Routine trichromacy is helpful for tracking down reddish-yellow fruit and seasonal leaves while polymorphic trichromacy is helpful for tracking down ripe fruits and insects (Melin, et.al, 2017). A QIAamp DNA stool Mini Kit was used to extract DNA from 111 fecal samples of mantled howler monkeys to observe their diet (Melin,
