In this episode, we trace the whole extraordinary story:🧠 Why building a human brain requires a biological hostile takeover of the mother's circulatory system⚡ Why ancient healers across Egypt, India, China, and Greece all concluded the same pregnant woman was being struck by demons or lightning — and why they weren't entirely wrong to reach for something otherworldly🔬 Why, in 2026, we still don't know exactly what causes eclampsia — despite 5,000 years of documentation and every tool modern medicine has🧬 The evolutionary circuit breaker modern humans developed that kept our mothers alive — and that the Neanderthals likely never got💔 The quiet mathematics of demographic collapse: what a 5% maternal mortality rate does to a band of 30 people over generations🚪 And the moment two researchers in adjacent buildings finally opened the door between them — and solved both mysteries at onceReference: Why reproduction has probably been very problematic in Neanderthals: The fabulous history of (pre)eclampsiaThis is Heliox: Where Evidence Meets EmpathyIndependent, moderated, timely, deep, gentle, clinical, global, and community conversations about things that matter.  Breathe Easy, we go deep and lightly surface the big ideas.
