To heck with people who have lost arms and legs, now I'm actually seeing some real reason for us to turn this biological phenomenon into deployable technology! Larger and stiffer, eh?

I live in western Washington and we don't have many lizards, but with the only specie I found as a kid you could definitely tell which lizards had regrown their tails. They were a different color and have larger scales than the rest of the animal's body, and did look much stiffer. Same here.

(see e.g. <a href="http://en.wikipedia.org/wiki/Endochondral_ossification" rel="nofollow">endochondral ossification</a>). Maybe these regrown lizard tails were examined before bone conversion took place. Or maybe the lizards have evolved to skip bone conversion as being wasteful. None the less this regeneration is probably the same process used by salamanders and some fish which does eventually regenerate limb bones so it is rather stupid to conclude that studying lizard tail regeneration is inapplicable to devising some scheme for human regeneration.
