hbd = human biodiversity: the diversity found among and between human populations that has a biological basis.

humans differ from each other on both individual and group levels due to variations between individual genotypes as well as average differences between population genotypes, the differences resulting via evolutionary processes. these differences include, but are not limited to, physical appearance including height, personality traits, intelligence, athletic ability, and health.

hbd research is conducted in numerous academic fields and their subfields such as biology, genetics, medicine, neurology, psychology, and anthropology. hbd research also draws on social, historic, and prehistoric data related to human populations.
