Explanation / Answer

1) Answer: D) bipedal locomotion

In ardipithecus, there are diverging big toes on the foot bones and the foot bones are larger and not the tarsals. This suggests organisation that supports bipedalism.

2) C) answer: bipedal locomotion, shorter arms, non opposable toes, downward pointing foramen magnum

In Hominins, legs started to become longer, and started to become way more stronger as compared to their arms.
