Veritasium takes us on a whirlwind tour of 4 billion years of evolution, starting with why poop smells bad (it’s a microbial defense tactic), moving to the very first spark of life, and diving into gene mutations that fuel diversity. Along the way we see how scientists simulate evolution on computers to watch natural selection at work and learn exactly what traits—and sneaky survival strategies—you and your family actually pass on.
We also get the low-down on kin selection and Richard Dawkins’ “Selfish Gene,” all wrapped up in vivid animations and real-world experiments. With expert insights from top researchers, this video shows how evolution isn’t just a theory in textbooks but a constantly running “simulation” that shapes every living thing on the planet.
