Ardipithecus ramidus (By Faren and Matthew)

The ardipithecus remidus was was discovered by Tim white in around 1992-1994 in Afrika. It is assumed that it was bipedal, but probably wouldn't be able to run well. It had 5 toes, including a smaller one and a large opposable toe, almost like a toe that was used to help it climb around the tree tops. Therefore, it is assumed that it was a quadraped in the trees. The skeleton is estimated to be around 4.4 million years old
