Ancient Humans Master Art of Tool-Making
Reading
Early humans cared about the rocks they used. They wanted good rocks to make tools long ago. This is what new research tells us about the Old Stone Age.
These early people made stone tools to use daily. They knew where to find good rocks far away. So, they traveled to get the right rocks for tools.
About 2.6 million years ago, people made sharp stone flakes. They hit rocks together to make these flakes. These flakes were like blades to cut meat from animals.
These blades helped them eat big animals. They cut the skin of hippos at a spring. But some rocks made better blades for tough hippo skin.
Scientists found good blades made of a rock called quartzite. This rock came from streams far away, about 8 miles. This shows early humans planned and knew where to find it.
