Millions of years of dangerous co-dependence, betrayed with diabolical precision. This is the story of figs, their wasps, the wasps' wasps, and Lyndzee & Rachel's descent into isolation-related madness.
The title says it all, but this episode has everything Rachel loves: phylogeny, prehistoric Kansas, evolution, physiology, and (duh) dinosaurs--but all through the lens of the evolutionary history of copulation through penises. Duck penises are even cooler than you thought. Here's what we know about dinosaur sex.
Explosive erections, vaginal dead ends, seasonal penises, and vaginas in VR? It must be time for Rachel's favorite Naughty Nature episode so far: waterfowl and their co-evolving genital cold war. Hold onto your butts, because it's time for a deep dive.
