Answer:
Explanation:
Vestigial structure: A biological structure that lost most or all of its origional function over the course of evolution. Example: Wisdom teeth or human appendix.
Analogus structure: Are biological structures with similar or corresponding functions but not from the same evolutionary origin. Example: Birds, bats, and butterflies all have wings that serve the same purpose but do not share ancestry with one another,
Homologous structure: Are biological structures in different animals with similar locations and structure but not the same purpose. Example: A human and a dog both have limbs but a human will use its arms for grabbing, picking pushing and etc while a dogs "arms" is only used for getting around.
Something they all have in common is the fact that all structures provide evidence of evolution. Something that defines each anatomical structure is that each of the three have evovled into different paths for functionality in an animal. Hope this helps!
