🦧💥🧠 Lead, Language & Legacy: How Lead Shaped Human Evolution
Manage episode 515882555 series 2740117

🧠💥 Could lead poisoning have helped shape human evolution? A bold new hypothesis suggests that Homo sapiens may have survived while Neanderthals and Denisovans vanished—thanks to genetic defenses against environmental lead. 🧬

👣 Sometimes, evolution turns adversity into advantage.
