Answer:
Although people living in low latitudes have high levels of eumelanin, this pigment can be found in people around the world (because it is predominant in people with brunette hair)
Explanation:
In animals and humans, melanin pigments play key roles in eye, hair, and skin coloration. Basically, there are three main types of melanin pigments: eumelanin (brown-black and insoluble), pheomelanin (yellow-red and soluble in alkali solution) and neuromelanin (found in some parts of the brain). Eumelanin is predominant in black people and brunette hair people, this being consequently found around the world. There are two distinct classes of eumelanin: black eumelanin and brown eumelanin, which differ in their patterns of polymeric bonds, and they have an incidence on the type of coloration (e.g., black eumelanin is found in people with grey hair).
