Human bones are lighter with time

The lack of osteoporosis makes human bones lighter, increasing the risk of fractures and osteoporosis.

Science Mag says that a dense bone of a chimp contains a small structure called a spongy bone . Thanks to CT scanning technology, researchers discovered the bones of modern chimpanzees, primitive human apes Australopithecus africanus, Neanderthals, and Homo sapien, which have a much higher density of porous bone than modern humans today.

Factors that drive change can be a sedentary lifestyle of people.

When comparing the density of porous bone in the hip joint between primates; the hunters of ancient gatherers and ancient farmers, the experts found the hips of hunters and gatherers were almost as strong as monkeys. Meanwhile, the ancient farmer's hip joint lacked significant bone.

Scientists conclude that modern human skeletons are increasingly weakened by the lack of regular and rigorous training, not due to evolutionary pressure.
