Beware small biases: the case of height

See prior post on self vs. other measurements of personality for a similar take. Height is the favorite trait in ‘behavioral’ genetics: it’s easy, fast and cheap to measure, continuous as opposed to dichotomous or discrete, highly polygenic, highly heritable, and no one complains to the PC police about it.

Species genetic variation and number of subspecies/races/breeds/breeding populations/clusters etc.

A straightforward research idea: Compare the recognized count of subspecies (races/breeds/breeding populations/clusters etc.) with measures of genetic variation.

Medical hypotheses, 74(1), 195-201. Fuerst,…
