Which describes vestigial structures and how they relate to evolution? snakes have tiny hind leg bones, indicating that they likely descended from lizards humans and dogs have similar bone structure in their forelimbs indicating a common ancestor dolphins and birds have structures that are adapted for swimming, but the structures did not evolve the same way the dna of mice and chickens shows similar patterns suggesting that the two species are related

Snakes have tiny hind leg bones, indicating that they likely descended from lizards.

Explanation:

Vestigial structures are the structures in an organism which are no longer in use. In past these vestigial structures performed some important functions in those organisms but gradually due to evolution now they have become non functional in their body. Lizards and snakes both are reptiles but lizards have a functional hind limb which helps them in crawling, snakes have been evolved from lizards but in order to move they creep rather than crawling so their hind limb does not serve any function in movement. Hind limbs are present in their body as a vestigial organ.

it depends on how much it could carry.
