Biology Ev16 Quiz Comparative Anatomy

Comparative ________________ is the study of the similarities and differences in the structures of different species.

• Evolution

• Embryology

• Physiology

• Anatomy

These are structures that are similar in related organisms because they were inherited from a common ancestor.

• Homologous Structures

• Analogous Structures

• Vestigial Structures

• Radiative Structures
