3. Useful Terms
Comparative Anatomy: The study of similarities and difference in the anatomy of different species.
Homologous structures: Body parts in different species that have the same evolutionary origin but differ in structure and function. Example, wing vs. arm bones
Analogous Structures: Body parts in different species that have similiar funtion but evolved seperately. Example, pengin fins vs. dolphin fins
Vestigial structures: Body parts that were functional in a species’ ancestors, yet appears to have no current function. Example, pelvic bone in whales.
