Gradelevel9th through 11th grade. Students will learn about comparative anatomy and examine structures that are similar and different in both modern and ancient organisms. Homologous structures refer to organs or skeletal elements of animals that by virtue of their similarity suggest their connection to a common ancestor while vestigial structures refer to the structures in an animal that has lost all or most of its original function in the course of evolution.
