Color processing in the primates

Color is only a few mammalian features. In the book on K. Tansely's visual system, a visual commentary on vertebrates states: The word tricomatic comes from the theory advocated by the French physiologist Palmer in 1777. It states that the human retina has an infinite number of molecules of three different types. These types are used to detect colors such as red, blue, yellow.

Changes in color vision of primates are unique among most authentic mammals. Remote vertebrate ancestors of vertebrate ancestors have a three color vision (trichromaticity), but in the night, warm blooded animals, mammalian ancestors, during the Mesozoic, have three conical I lost one. Therefore, fish, reptiles, and birds are three or four colors, and all mammals, except some primates and marsupials, are dichroic or monochromatic (completely color blind). Night primates such as monkeys and jungle babies are usually monochromatic. Carolyn was usually trichromatic as the red green opsin gene was duplicated in that line between 10 and 40 million years ago. On the other hand, Platyrrhines is only three colors in some cases. Specifically, individual females must be heterozygotes of two alleles of the opsin gene (red and green) at the same locus on the X chromosome.

There is no actual blindness, only the specific color or color can not be seen, so the name of color vision abnormality may be deceived. Color blindness is a more appropriate name for this disease, as it defines a better illness.

Dogs and cats, and most other mammals, do not see rainbows other than primates. They do not have a three-color vision like human beings, so they only see a part of the visible spectrum. There are nearly three kinds of pyramidal cells in the primates, each focusing on a specific range of visible light, so you can see all the colors to a certain extent. Most other mammals have only two kinds of cones, so they look less color. Many people with color vision suffer similar problems - one or more cones do not function properly, so part of the spectrum is not very well visible. (There are other types of color blindness, but the most common thing is that the cone is missing.)
