Human color vision is based on biological characteristics that animals have obtained in the course of evolution. Unlike most other mammals, which are dichromatic, most primates are trichromats. Why has trichromatic color vision evolved in primates? Trichromatic color vision improves the ability to discriminate redness from greenness. Therefore, it was initially believed that trichromatic color vision evolved because it is adaptive to detect reddish fruits from greenish leaves. However, research that compared behaviors of some New World monkey species whose social groups generally consist of both dichromatic and trichromatic members has not demonstrated clear advantage of trichromats for fruit foraging in the wild. In this talk, I will introduce studies that tried to understand the evolution of color vision in primates. |
