Actually, that's not exactly true. The hatchet blade was invented first. They invented it once and didn't change it for 10,000 years. Then a new species of humans invented the haft and attached the blade to it. They didn't change all that much for a couple thousand years either. And then we slowly started developing things faster and faster. Eventually we actually got to this point after like 12 species.
