The Surprising Truth About 4 Billion Years of Evolution

This Veritasium video takes you from the smelly origins of life (yes, poop plays a role) to the first self-replicating molecules, showing how random mutations and digital simulations help us see natural selection in action. Along the way, you’ll learn what really gets passed down through generations and why some traits stick around.

It then dives into social tricks like kin selection and Richard Dawkins’ “Selfish Gene,” wrapping up with the idea that our entire understanding of evolution is, in a way, just another simulation. Expert interviews, slick animations and a touch of humor make 4 billion years of science surprisingly fun.
