New species of human found in Kenya

Scientists have discovered a new species of human that lived two million years ago.

Experts looking at fossils found in northern Kenya in Africa now think that there may have been up to three different types of humans living in the area.

The bones show that the human's had a large skull and a long flat face, very different to how we look today.

Only one of them, the Homo erectus, is thought to be our direct ancestor.
