Archaic Revival, by Terence McKennaRead about the other entries on the list.
Inside my memory, one of the central arguments made by this book is that the evolution of primates dramatically accelerated when a tribe of prehistoric apes consumed a specific variety of psychedelic mushroom. Now, it’s been a long time since I read Archaic Revival, so maybe I’m remembering this incorrectly. Maybe that particular argument is not even in this particular book. But if I’m wrong, it’s almost certainly because of books like this.
