The stone age was when early humans made tools and weapons out of stone.

It lasted from when the first stone tools were made by our ancestors about 3.4 million years ago until the introduction off metal tools a few thousand years ago.

People ate nuts and berries and hunted animals for meat and skins.

They lived in a cave or shelters made from animal bones and skins.
