Hiccups Are a 370-Million-Year-Old Glitch

It always arrives at the worst possible moment. Mid-sentence, mid-meal, maybe mid-date — and then, out of nowhere, your whole body jerks. Hic. You hold your breath, you sip water upside down, someone offers to scare you, and none of it really works. A hiccup is one of the most useless things your body does. It serves no purpose, fixes nothing, and protects you from nothing. So why do you have a dedicated reflex, wired into your brain, for doing something completely pointless? In this video you'll discover the strange answer: hiccups are a leftover. The exact muscle pattern of a hiccup — contract the breathing muscle, snap a flap shut over the airway — is almost identical to how tadpoles and amphibians pump water across their gills (a match first spotted by the neuroscientist Christian Straus). As Neil Shubin explains, it's ancient wiring you inherited, almost unchanged, from fish that lived hundreds of millions of years ago. A hiccup is that old gill-breathing program, switching on by accident. You'll also meet the man who hiccupped for 68 years straight — and learn why the weird cures sometimes actually work. So the next time a hiccup ambushes you, remember: it's not a flaw, and it's not random. It's a fossil, still working. For just a second, your body is breathing underwater.
