Most Boids have had vestigial limbs from the early-mid Cretaceous period(200 -100 million years ago when earlier before that they started to loose their working limbs. They then started to take on the"snake" appearance as they do now. If you watch a boa while trying to mate, the 2 "claws" spurs move about in a circular pattern, it is quite interesting movement which might show that these had a greater use somewhere in the distant past.
