Bone is one of the strongest materials found in nature. Ounce for ounce, bone is stronger than steel since a bar of steel of comparable size would weigh four or five times as much.
Researchers discovered that the arms and legs of recent modern humans are lightly built compared to modern humans from before the Holocene Epoch, which began about 12,500 years ago. Rather than shifting gradually over time, bone density remained high throughout the history of modern human evolution, until the Neolithic revolution when bone density decreased dramatically.
In other-words, modern human skeletons have a substantially lower density in joints throughout the skeleton than compared to our predecessors, which suggests that this change may have been linked to a reduction in long distance activities, and food habits due to a shift from a hunting and foraging lifestyle, to a sedentary one.
These insights help us understand modern conditions such as osteoporosis, a bone-weakening disorder that may be more prevalent in contemporary populations, due partly to low levels of daily distance walking activity, not enough activities that strengthen muscles, and the modern Western American diet that robs our bodies of vital nutrition.
Activities that put stress on bones can nudge bone-forming cells into action from hanging, pulling, holding, tugging, and pushing on bone that occurs during strength training, as well as weight-bearing aerobic exercises like walking or running. The results are stronger, denser bones and the best part is that most, if not all these strength activities, can be done indoors and outdoors without exercise equipment.
Understanding our skeletal health today points to the importance of daily physical activities, whole food nutrition, sustain sleep, and developing a positive mindset to embrace an active lifestyle.
