IHO at the "cutting-edge" of research in early tool technologies
Two published papers—one each in Nature and Science—document a two-step process of projectile weapon evolution that ultimately allows modern humans to conquer the planet—building a projectile and then figuring out how to hurl it with greater distance and accuracy with assisted leverage—the root of everything from hurling spears to artillery to spaceships whipping around planets.
