In this 2-part series, we explore how modern scientists and sociologists are thinking about biological sex development and gender... and how that differs with past ideas. Here, in part 2, we’ll focus on how gender is constructed, its biological basis, and how mismatches between sex and gender can play out in real life. Guests: Janae Kroc, Dr. Krista Scott-Dixon, Alaina Hardie, Dr. Vincent Harley.
