After 40 years of searching, researchers can finally put a new face on a mysterious human ancestor whose skull was discovered 40 years ago in Kenya.

It also shows that there were several species of Homo present 1.78 million to 2.03 million years ago in the Rift Valley of Africa, and that they probably had to adapt in different ways to coexist.
