Explanation:
There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees.
