Do primates have trichromatic vision
WebPrimates, as an order of mammals, began to emerge around the beginning of the Paleogene Period. Primates have re-developed trichromatic color vision since that time, by the mechanism of gene duplication, being under unusually high evolutionary pressure to develop color vision better than the mammalian standard.
