Archaeologist found 2 million year old fossils and possibly skin from a pair of primates. This primate is know as the Australopithecus sediba and it was discovered in Malapa region in of south Africa in 2008 and was described the first time last April. Scientist made many test and for example the primates anatomy showed that it is able to make and use tools. They also found what they think is fossilized skin, So they made a open-access experiment.They say that they bones are from a really special ere that we don't know much about. The two primates fell in a chasm and they bacteria trap persevered them. From the legs they saw that their ankle is similar to ours and that they could walk on two feet. The odd combination of feet suggested that they could also climb up trees as well as walk. The endocast showed that the brain was similar to ours but small. The primate had a long thumb so it had a precision grip. In fact they say that they might have had better grip then us because of their longer thumbs. This could change history but the Washington sate university is not yet ready to make drastic changes to the time line.
