Somewhere in a dense forest of ash and elm trees, a hunter readies his spear for the kill. He hurls his stone-tipped weapon at his prey, an unsuspecting white-tailed deer he has tracked since morning. The crude projectile pierces the animal’s hide, killing it and giving the hunter food to bring back to his family many miles away. Such was survival circa 5,000 B.C. in ancient North America.
But today, the average person barely has to lift a finger, let alone throw a spear to quell their appetite. The next meal is a mere online order away. And according to anthropologists, this convenient, sedentary way of life is making bones weak. Ahead, there’s a future of fractures, breaks, and osteoporosis. But for some anthropologists, the key to preventing aches in bones is by better understanding the skeletons of our hunter-gatherer ancestors.
