Snake w/ foot found?

[icygirl]

sweet. must be some form of genetic defect causing the gene that signals not to grow limbs to fail. They did something like this to chickens on a discovery channel show to prove birds came from lizards/dinosaurs. they disabled the gene that stopped the production of teeth and I believe they made a chicken with scales or something. Don't remember for sure. Granted this snake is a wild animal not an experiment. Pretty interesting.

Is that really true that there's a gene for "no legs"? I thought the legs genes just decayed over time until they became unreadable.
