I don't want to see a new better more efficient hand, I want to see something better than a hand, that has never before existed, if the claim is that every single limb came from NS + M.
Unlike most here, I think this is perfectly reasonable. After-all, if in just over one third of a billion years, evolution has taken us from an extreme of four limbs, a body, a head and a tail to our modern human four limbs, a body, a head, BUT NO TAIL, just imagine what we should be able to do in the lab
