Loss and regain of colour vision during the evolution of primates
Baboons, like other old world monkeys and apes, have eyes which can discern blue, green and red wavelengths of light
The evolution of color vision in primates is highly unusual compared to most eutherian mammals. A remote vertebrate ancestor of primates possessed tetrachromacy,[1] but nocturnal, warm-blooded, mammalian ancestors lost two of four cones in the retina at the time of dinosaurs. Most teleost fish, reptiles and birds are therefore tetrachromatic while most mammals are strictly dichromats, the exceptions being some primates and marsupials,[2] who are trichromats, and many marine mammals, who are monochromats.
