• Question: Can people use the DNA or the brain systems of lizards to regrow limbs or fingers (rather than clot and heal) or if the was a hole in your chest? I think people have, but what do they use?

      People haven’t done it fully for humans yet. We are fairly certain of the DNA parts of lizards that make them regrow their limbs but we’re not completely sure how they interact to make lizards heal. People are studying this at the moment to find out how to do it.
      If we can work it our then it’s possible that we can start regrowing limbs for people but as always, this will take a very long time to work out fully.

      Well, this doesn’t discuss lizards, but it does describe how pigs helped to regrow someone’s finger…here’s the link:http://health.howstuffworks.com/human-body/systems/musculoskeletal/extracellular-matrix.htm. Not sure if this has happened too often though.
