Scientists have discovered chimpanzees use rocks as tools. Chimpanzees sharpen rocks by hitting them to a tree or another rock, so it got strong, enough and durable. The sharpen rocks is for breaking food apart into little proportions, so the babies can eat the food easier.

Scientist studied chimpanzees in the Nimbia Mountains of Guinea, Africa the chimps were seeing using the rocks and wooden cleavers to break hard nuts into smaller proportions eat.
