Primates
How to Change Your MindPrimates appear in the book’s index as a topic associated with mushroom consumption, alongside a separate reference to the evolutionary role of Psilocybin. The references establish a place for primates in the book’s wider discussion of mushrooms and evolution, but do not provide a specific account of the animals or their behavior.
Indexed References
The index directs readers to a discussion of primates’ consumption of mushrooms on pages 97–98 and 123. It also lists the role of Psilocybin in evolution on pages 115–116. These are distinct references: one identifies primates and mushroom consumption as a subject, while the other names an evolutionary question concerning the compound.
Scope of the Account
The available references do not identify the primate species, the mushrooms involved, or the circumstances of consumption. Nor do they state how the discussion of primates relates to the book’s treatment of Psilocybin’s evolutionary role. The evidence therefore supports recognizing primates as part of the book’s animal-and-mushroom subject matter, but not drawing conclusions about particular species, effects, or evolutionary mechanisms.
