Human Ancestor May Put Twist in Origin Story

There was a discovery of two million years old bones, and maybe skin. Archeologists think they found fossilized skin , but they can not be sure. What makes these bones more special is that they are Australopithecus Sediba. That is a type of humans before us. They have smaller brains than us, but bigger ones than chimpanzees. These people are a mix between humans and apes. They probably had a better grip than us because they had a longer thumb. The Sediba's were able to use and make tools. They were around four feet tall which surprised me, I thought they would be smaller and not so close to our size. These discoveries were history changing.

This is one of they things that they found.
I found this picture and passage from National Geographic
