But the mutational "hotspots" also differ in modern man.

The second is not available to the general public, but the first argues that "a significant portion of the effort of early cultivators globally was probably directed to the production of psychoactive substances, including the use of cereals, poppies, coca, sugar cane, tobacco, and cannabis," and that "a major component of the Neolithic transition was a pharmacological transition" using psychoactive substances.
What might head a list of the defining characteristics of the human species?
