Definition: The word "anthropoide" means "manlike". It's a genus of animals that include humans and primates, which includes chimpanzees, gorillas, orangutans, and many more. Detailed definition: These animals have features common to both man and other mammals, such as hair on their backs, skin that can change color and texture depending on the environment (like fur), and teeth made of keratin instead of bone for better strength and flexibility in biting action.
