Joints have certainly benefited from evolutionary development. Stephen Jay Gould, the Darwinian who proposed the theory of punctuated equilibrium, often points out that the products of evolution are not "progressive" but "adaptive." This means that key evolutionary features have allowed for major functional improvements--like JOINTS--but they may be associated with less than desirable "side effects"--ARTHRITIS and JOINT TRAUMA. I think most of us would accept the latter as small prices to pay for walking upright, dancing, playing tennis, and painting! Appreciate your joints today!

Be kind to your joints!
