Summary:
- The article discusses the evolutionary mismatch hypothesis, suggesting that human bipedalism and the increased load on joints may have rendered us more susceptible to osteoarthritis compared to our primate ancestors.
- It highlights research comparing human skeletal remains with those of chimpanzees and bonobos, indicating that the shift to an upright posture has fundamentally altered joint biomechanics in a way that predisposes modern humans to degenerative joint disease.
