A person's environment is influenced by social and cultural circumstances

Racial inequality exists in many societies. Though it is true that people of different races outperform one another in the realms of education, athletics, wealth, and health, these differences are due to a person's environment - not their innate genetics or biological makeup. One of the first anthropologists to challenge the idea that race is biological was Franz Boas (1858-1942). Boas showed that cranium size - evidence which evolutionary anthropologists and race scientists used to support their arguments that intelligence differences between races was biologically innate - was more affected by environmental factors such as, for example, differences in nourishment.^[1]
