Humans have been making new things since we found a rock in a cave and made it into a thing to hit other things with. While we're not the only species who uses tools - animals have sometimes been spotted using a stick to dig, for example - we're definitely the species who took it the farthest. Some of the things on this list are truly world-changing inventions, like the polio vaccine. Polio was a devastating disease prior to the development of the vaccine that's made it much, much rarer in wealthy countries. But what year was it invented?
