Question

what is the difference between the lesser apes and great apes? click to add text

Explanation:

Lesser apes (like gibbons) are smaller, have longer arms for brachiation, and less complex social structures. Great apes (chimps, gorillas, orangutans, humans) are larger, have more complex cognition/social systems, and different locomotion (e.g., knuckle - walking for some great apes). Key differences include size, anatomy (e.g., great apes have a broader chest, no tail; lesser apes have a tail - like vestige and slimmer build), social behavior (great apes have more complex family groups, tool use in some), and cognitive abilities (great apes show higher problem - solving, self - awareness).

Answer:

Lesser apes (e.g., gibbons) are smaller, have longer arms for brachiation, simpler social structures, and lack the complex cognition/physical traits (like broader chest, no tail vestige) of great apes (e.g., chimps, gorillas). Great apes are larger, have more complex social/cognitive abilities, and different locomotion (e.g., knuckle - walking).
