Color Vision Deficiencies and the Evolution of Color Vision in Primates

The ability to see color is what everyone thinks is a matter of course. However, when experiencing a visual experience indeed through color vision anomalies, many think that their visual is "ordinary". Typical people rely on the fruit color to determine their maturity. I see a signal in the brain that the green banana is still immature and not ready to eat; look at the brown banana, if it shows that it is boiled down, use it to throw it away or bake it You should.

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.

Several problems regarding color vision are not caused by genetic mutation. These non-hereditary conditions are explained as acquired color blindness. They may be caused by other eye diseases such as diseases involving the retina, nerves that carry visual information from the eye to the brain (optic nerve), or regions of the brain that process visual information. Acquired color blindness may also be a side effect of certain drugs such as chloroquine (used for the treatment of malaria), or exposure to certain chemical substances such as organic solvents.

Explanation: Color vision abnormality, also called color vision abnormality, is defined as invisible color or invisible color difference. 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 vision abnormality is a better name for this disease because it better defines this disease. - Color vision and baby human knows the color before learning something else actually, as long as their vision develops, they begin before learning alphabets or even numbers. Before we told our name, we learned to recognize colors very well. This is how babies know their parents and other well-known ones. The color influences how we perceive the world around us, gives a psychological effect to our emotions, and distinguishes our (good or bad) preferences.
