🧠💥 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. 🧬
By analyzing fossil teeth 🦷 and testing brain organoids 🧪, researchers found that ancient lead exposure disrupted key language-related genes (like FOXP2)—but not in modern human variants.
👣 Sometimes, evolution turns adversity into advantage.
