Final answer:
Chimpanzees have a specialization for brachiation that humans do not have, which is the ability to use tools for hunting.
Step-by-step explanation:
Chimpanzees have specialized adaptations for brachiation, or swinging through trees, that humans do not have. One specialization for brachiation found in chimpanzees but not in humans is the ability to use tools for hunting. For example, chimpanzees in certain regions use sticks as spears to hunt prey, while humans do not exhibit this behavior. This adaptation allows for a stronger grip on branches when swinging through the trees. In humans, the big toe is aligned with the other toes, which aids in bipedal walking but is not suited for brachiation like in chimpanzees.
