Detailed explanation-1: -No, snakes do not have hip bones. Some snakes retain small spurs of bone where their ancestors once had hips and some even have tiny bones of vestigial legs embedded in their muscles, but they do not have the pronounced or functional hip bones now that snakes no longer have legs.
Detailed explanation-2: -A Snake–With Legs! Pythons and boa constrictors have tiny hind leg bones buried in muscles toward their tail ends. Such features, either useless or poorly suited to performing specific tasks, are described as vestigial. They are also intriguing evidence of the evolutionary histories of species.
Detailed explanation-3: -How do the hip bones of a snake provide evidence for the evolution of snakes? The hip bones are vestigial structures that show evolutionary descent from an ancestor that had legs.
Detailed explanation-4: -Structures that have lost their use through evolution are called vestigial structures. They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose.
