boas and pythons are some of the oldest species of snakes around, it is common for people to use a visual of the animals vestigial spurs to try to sex the animal, the larger spurs are used by the male to stimulate the female during breeding. If you look at a skeleton of either of these species the pelvic girdle and spur/leg remenants are quite visible. All life seems to have come from the ancient seas. Whether snakes evolved from lizards was your question, the best answer is that at some point in history snakes and lizards shared a common ancestor, as did man and apes, whether this ancestor was already a true lizard or not we won't known until the fossil record is more complete.
