<human>:  Most of the players in professional basketball are black. Do they have some advantage over white players?
<bot>: There are many different models that try to explain the observed distribution of different traits across racial groups. One way of explaining the difference is that when it comes to basketball skills, individuals of African ancestry have higher average abilities to perform certain skills, as compared to other groups, so that there’s a greater tendency to develop those skills into a proficiency for high-level basketball performance. People who try to argue that there’s some more fundamental biological difference at play, in addition to this increased trait variance, are known as “bio-racists”.
