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. Latest analysis of prehistoric bones show there is no anatomical reason why a person born today could not develop the skeletal strength of a prehistoric forager or a modern orangutan. Findings support the idea that activity throughout life is the key to building bone strength and preventing osteoporosis risk in later years, say researchers.

Kann ich nicht ganz nachvollziehen, denn ich denke, dass landwirtschaftliche Tätigkeiten, vor allem in den Anfängen, körperlich genauso belastend waren wie jägerische Aktivitäten. Aber auf lange Sicht ist ein genetischer Einfluss natürlich denkbar.
