Nope.

I asked a question on here a while back about broken bones & amputation

Look in particular at Chris's reply.

If you break a bone then as it mends it fuses together as a few of mine done in the past. Also a broken bone that's been mended
is stronger than before or so I've heard.

But once your limb is amputated then the nerves are dead and
cannot grow again. Hope this helps a bit

Rosalind Franklin was my first cousin and one my life's main regrets is that I never met this brilliant and beautiful lady.
She discovered the Single DNA Helix in 1953, then it was taken by Wilkins without her knowledge or agreeement.

If you were an amphibian it would regrow, but mammals are not amphibians.

Interestingly, I have heard stories about some forms of breast cancer get the local cells so confused that they start growing teeth where no teeth should be, and people are studying this as a way of getting the mouth to regrow teeth.

It is conceivable that you could regrow limbs in humans, but you would need to switch on the genes that the embryo would use to grow its limbs.

And switch them off again when the limb was the required size. That, to me, is 1 of the most interesting aspects of cells & growth - how do they know when to stop making you grow?

Is a lizard an amphibian?

There was a claim not too long ago about a person regrowing a fingertip, found this on google http://www.breitbart.com/article.php?id=D8NCIHHG0&show_article=1 Not sure if its true or not

A Lizard is reptile, a cold-blooded creature liked snakes are.

Did you know that the leatherback turtle is the only warm-blooded reptile? Isn't that interesting!  [;D]

Think you might find some of the big crocks manage to raise their core temperature too. There is also some controversy over whether Dinosaurs were warm blooded reptiles
Science is continually evolving. Nothing is set in stone. Question everything and everyone. Always consider vested interests as a reason for miss-direction. But most of all explore and find answers that you are comfortable with
