10. Vestigial Structures



This is a picture of a dandelion. Dandelions are an example of organisms with vestigial structures. Vestigial structures are structures in an organism that lost all or most of its original function over the course of human evolution. Dandelions have the organs for sexual reproduction (stamen and pistil) but reproduce using asexual reproduction. Other examples of vestigial structures are the human appendix and the human coccyx (tailbone).
