Terence McKenna's 'Stoned Ape Theory' of Human Brain Evolution | Heather Heying & Bret Weinstein

Terence McKenna once proposed that the large growth in the human brain may have been catalyzed by human's use of psychedelic mushrooms. Heather Heying & Bret Weinstein discuss whether this idea is likely to account for human brain evolution and what other factors may have been the primary drivers of the increase in human brain size.

Terence McKenna obviously did not understand heredity. He clearly made an error of Lamarckism, i.e. that acquired traits, or in this case, states (!), could be passed to offspring. I do not understand why do people give any weight to this hypothesis.
