Prehistoric peoples: the first humans
The first prehistoric humans who looked most like us lived in parts of Africa nearly 2 million years ago
These early humans walked on two legs so they could see over the tall grass and look out for wild animals.
About 600 000 years ago they made tools and weapons out of stone, bone and wood.
They hunted wild animals and caught fish.
They made clothes out of the fur of the animals they hunted.
They collected and ate fruits and nuts.
They lived in caves.
About 200 000 years ago prehistoric humans learned how to make fire.
Groups of prehistoric humans spread out to live in many different places on the Earth. Small groups of people lived in Africa, Europe, Asia, and Australia.
Those people who lived in hot places had darker skin than those who lived in cold places.
Some of the people painted pictures on the walls of their caves.
In parts of Europe where it was very cold, the people built houses made of the bones of the woolly mammoth which they covered with the skins of the mammoths and other animals that they hunted.
