The episode’s topic is language and the stories that allow people to cooperate at a large scale. The program connects the discussion to the “Tree of Knowledge” chapter in Sapiens and considers hypotheses about human change. This article describes the framework presented by the book’s author and the program’s speaker; it does not treat every hypothesis as a settled conclusion in anthropology.

This article is a guide to the episode’s discussion, not an academic review of human evolution.
