2 Homonoids Gibbons, great apes (orang-utan, gorilla, and chimps) and also humans.

3 Homonoids Gibbons, great apes (orang-utan, gorilla, and chimps) and also humans. They differ from the Old world monkeys because of brachiation (swinging by the arms from branches).

4 homonoid differences Powerful arms are longer than legs.

5 homonoid differences Powerful arms are longer than legs.
Chest is flatter from front to back.

6 homonoid differences Powerful arms are longer than legs.
Chest is flatter from front to back. Absent tail.

7 homonoid differences Powerful arms are longer than legs.
Chest is flatter from front to back. Absent tail. More mobile shoulder and forelimb. Supination (ability to rotate forearm) enables branches to be grasped from any direction.

8 homonoid differences Powerful arms are longer than legs.
Chest is flatter from front to back. Absent tail. More mobile shoulder and forelimb. Supination (ability to rotate forearm) enables branches to be grasped from any direction. Reduced thumb and not fully opposable. Objects are gripped between thumb and side of first finger.
