If we seek confirmation of these messages from evolutionary science, we won’t find the Tree of Knowledge, of course, but we still see a major unexplained transition. We understand now that humans evolved from apelike ancestors over a period of 5 million to 6 million years and that such gradual evolutionary processes are not uncommon to life on earth. But in roughly the last 50,000 years, something unique happened, which some call the Cognitive Revolution and others (with a touch of irony) call the Great Leap Forward.
