Explanation:

Vestigial structures are body parts that remain in an organism but have lost their original major function through evolution. The dolphin's hip bones, snake pelvic bones, and human appendix all fit this definition as they no longer serve their ancestral purpose. Homologous structures share a common origin but may have different functions, while analogous structures have similar functions but different origins, which do not match the description here.

Answer:

vestigial structures
