Detailed explanation-1: -Chimp bones are densely packed with microscopic structures known as spongy bone. Human bones aren’t. That relative lack of spongy bone makes our skeletons lighter and increases our risk of fractures and osteoporosis.
Detailed explanation-2: -Mammals, reptiles, birds, fish and amphibians are vertebrates with endoskeletons (skeletons inside their bodies). Their skeletons provide support and protection and help them to move.
Detailed explanation-3: -As the skeleton of a chimpanzee (1) and gibbon (2) to the right show, apes have short backs with wide, barrel-shaped chests and robust pelvic girdles. The length of spine between rib cage and pelvis is much shorter in apes than in monkeys. These features are related to the upright posture of their bodies.
