If you’ve ever wondered why evolution really matters (and yes, even why poop smells bad), this Veritasium video takes you from life’s humble beginnings through gene mutations and natural selection. It breaks down how tiny genetic tweaks get passed on—sometimes for selfish reasons, sometimes to help your relatives—and even shows you a hands-on simulation of evolution in action.
Along the way, you’ll get fresh insights from top scientists, a peek at Richard Dawkins’ “selfish gene” idea, and a clear, informal roadmap to the core principles that make evolution tick. It’s a fun, fast tour that proves if you don’t grasp these basics, you’re missing the heart of how life really works.
