Human races do not exist
When we say that someone is black or white, we may think that he or she belongs to a biological category defined by his or her color. Many people believe that skin pigmentation reflects belonging to a race, “one of the main groups that humans can be divided into according to their physical differences, for example the colour of their skin; the fact of belonging to one of these groups”, according to the Oxford Learner’s Dictionary (similarly in Spanish: “each of the groups into which some biological species are subdivided and whose differential characters are perpetuated by inheritance”, according to the Spanish Royal Academy).
This notion, in the case of our species, is meaningless. From a biological point of view, human races do not exist.
In the skin there are melanocytes, cells that produce and contain pigments. There are two types of pigments, called melanin: one is brownish brown (eumelanin) and the other is yellowish red (pheomelanin). Skin color depends on the amount and proportion of both. This depends on different genes: some affect the amount of pigment in the melanocytes and others the proportion between the two types of melanin. Therefore, very similar colors may be the result of different combinations and obey different genetic configurations.
