Obviously. It's evidence that if you go back far enough, the snakes' ancestors had actual functional legs.
How does a duckbill platypus have a bill and lay eggs. It seems reasonable to decide that a duckbill platypus is a transitional form between a bird and a mammal. Except I have been assured from my high-school biology on to the present day that no biologist considers it so. It's just a mammal that has a duck's bill and lays eggs.
It's roughly the same shpe as a duck's bill, but anatomically it's quite different - for one thing its an electrosnsory organ. The platypus is actually a mammal that retains some reptilian features (like the reptile-like, as opposed to bird-like eggs, and many details of its skeletal structure)
Check this out Oolon Colluphid's Guide to Creation. Follow the links to find many examples of things like snake legs: platypus teeth (which never erupt), baleen whale teeth (which are reabsorsbed before birth), marsupial egg teeth (which are never used), etc etc
Another area in Genesis where the Bible writers got it right. The curse God put on the serpent was that it was to crawl on it's belly. Obviously it had legs before that and lost them.
