How the Skeletons of Our Prehistoric Ancestors Evolved to Modern Human Frames

It’s no surprise that modern-day human bone structure varies greatly from that of our ancient ancestors. As society has advanced and new technologies developed, so too has our bone structure.

Within the last 10 years, Ryan says many researchers have been able to access micro scanners and computer software that allow them to analyze and compare bones. “Early modern human bones were more robust,” Ryan says. “There seems to be a transition with the shift to agriculture. When we reduced our mobility and our physical activity, we began to not build as much bone because we weren’t as active.”

Although modern humans had less bone rigidity, some had more rigidity than others. Cross-country runners had more than swimmers. Controls were typically in the middle. The humeral rigidity, however, told a different story. The ancient women had greater humeral rigidity than modern women.
