In part two of my conversation with evolutionary biologists Bret Weinstein and Heather Heying, we discuss what evolutionary biology can teach us about sex, gender, adulthood, and religion. With the recent explosion in transgender identification across American society, along with the censorious condemnation of any criticism within polite circles, we must reexamine the nature of human individuality and our fundamental understanding of male and female. Bret and Heather give a thorough explanation of why biological sex evolved in the first place and how it’s actually defined scientifically. We then zoom out to see how this particular issue is just one facet of a broader cultural trend that’s undermining our ability to become true adults who are capable of leading productive, fulfilling, and moral lives.
