What happens when an evolutionary biologist examines gender theory through the lens of 4 million years of human evolution? Gary Clark's journey from living with Aboriginal peoples in Australia's Western Desert to studying sexual dimorphism in ancient fossils reveals how post-modern theorists claiming to "deconstruct" Western ideas are actually imposing them. As major universities embrace the notion that biology is "right-wing," Clark watches academia deny the very sex-based differences that structure every known human society. From his unique vantage point spanning primatology, paleoanthropology, and Jungian psychology, this scientist explains why denying biological sex isn't progressive—it's anti-scientific.
