Betweenabout 400,000 and 200,000 years ago, thepace of innovation in stone technologybegan to accelerate very slightly. By thebeginning of this time, handaxes were madewith fine craftsmanship. Blade tools madeof stone were created, but the emphasisshifted away from stone to artefacts madefrom materials such as bone, antler and ivory.Spears and bows and arrows made killing large animalseasier. Harpoons, or spears with sharp points, and fishhooks increased the number of fish caught. Early humansused sharp-edged tools to cut up plants and dig roots.
