What arguments can be made from criticism of racist theories?

People of all races are characterized by species characteristics:
• similarity of body structure (structure of the skull, brain, internal organs);
• physiological similarity (blood groups, diseases, protective reactions);
• the opportunity for unlimited crosses, resulting in prolific offspring;
• All are of one origin.
According to a person’s genes, one cannot accurately determine his race, therefore, in the genetic sense, races do not exist (but only signs that are dominant and recessive, different norms of behavior). Racial differences are the result of people’s adaptation to certain conditions of existence, as well as the historical and socio-economic development of human society.
