The article, “Howler monkeys may owe their color vision to leaf hue” depicts the effects that color can have on a species survival. The article suggest that the bright colors of the leaves have led to monkeys enhanced color vision. Howler monkeys have developed a taste for the vibrant red leaves. Research suggest that the monkey’s ability to differentiate between the red and green leaves helps them pick the more nutritious leaves. Although primates have acute color vision, many have some form of colorblindness. However, like Humans, Howler Monkeys have trichromatic vision. This trichromatic vision helps them select the more nutritious leaves. Additionally, when insects become unavailable Howler Monkeys supplement their diets with leaves from …show more content…
Darwin believed that evolution was a result of species modification. According to Darwin, natural selection is survival of the fittest species. However, natural selection is survival of the fit enough. An animal that is well adapted to their environment will survive even though they may not be the strongest animal. It is important for scientist to understand how adaptation helps a species survive in order to prevent extinction. Scientists can then use that information to create habitats that are beneficial for species on the verge of extinction. For example, if the Howler Monkey’s was on the verge of extinction, scientist can create natural habitats with the nutritious red leaves. This will facilitate in the growth of the Howler Monkey species. However, that specific habitat would lead to the demise of the other South American Monkeys with dichromatic vision because they would be unable to distinguish between the leave. However, the monkeys with dichromatic vision would thrive in a different environment where color is not as significant. The monkeys that are well adapted will then pass on their beneficial genes to the next generation. Those future generations have evolved to now have enhanced color
