Answer:
S- shaped spine, adducted hallux and formation of a calcaneous

- The adducted hallux is the big toe which has been aligned with the other toes , in primates the big toe is not adducted and is used much like the thumb is on a hand, to hold objects and climb trees. The big toe aids in balance as one stands on the flat ground
