CT Scanning the Femoral Head of Farmers and Foragers to Show Bone Mass and Fragility (VIDEO)
Caption
New research across thousands of years of human evolution shows that our skeletons have become much lighter and more fragile since the invention of agriculture -- a result of our increasingly sedentary lifestyles as we shifted from foraging to farming.
This clip shows the scanning technique used to measure the bone mass in the hip joint of hunter-gatherers and agriculturalists to show how our bones have become lighter and more fragile since our days as ancient foragers.
