There is no racial superiority. Since indigenous Africans and their descendants beyond its borders have black skin, it may create the impression that the dominance of black athletes in certain sports is related to their racial or ethnic origin. In fact, the emergence of black skin has another cause and is not related to a person's physical abilities. The reason for the dominance of black athletes is related to the features of their bodies' heat conductivity, namely the ability to timely and effectively dissipate excess heat outside the organism. The level of human body heat conductivity is not related to skin color, and it is determined by the ability of the cells to effectively dissipate excess metabolic heat into the intercellular space, which depends on the amount of chromosomal heterochromatin regions.
