Something Weird Happens When You Simulate Lifeless Molecules

This Veritasium video dives into how simple, non-living molecules can mimic evolution’s big moments—from why poop stinks (it’s survival chemistry) to the first self-replicators. Along the way, it breaks down gene mutation, natural selection, kin selection and even Richard Dawkins’ Selfish Gene, all brought to life with snappy animations and hands-on “Snatoms.”

Backed by experts like Jack Szostak and John Sutherland, the film combines real-world labs with computer simulations to show how lifeless goo can spark life’s takeover. Sprinkle in fun sponsorship plugs, a molecular modeling kit you can buy, and a healthy dose of science jokes, and you’ve got a neat, informal tour of evolution in action—even if it’s just bits on a screen.
