Final answer:
Mammals and primates have distinct features setting them apart from reptiles and other animals.
Explanation:
Mammals are a group of animals characterized by features such as hair or fur, mammary glands, and three middle ear bones. They are different from reptiles in that mammals typically give birth to live young, have a higher metabolic rate, and regulate their body temperature internally.
Three unique features of the mammalian skeletal system include a diaphragm to aid in breathing, specialized teeth for various diets, and a more developed skull with a larger braincase. Primates, like humans and apes, have derived features such as forward-facing eyes, grasping hands with opposable thumbs, and complex social behaviors that set them apart from other animals.
