• Anatomist (n): A scientist who specializes in anatomy.
• Morphology (n): The study of the form and structure of organisms. Comparative anatomy is a sub-discipline of comparative morphology.
• Homology (n): The similarity in structure due to common ancestry (a key concept in comparative anatomy).
• Analogy (n): The similarity in function but not in evolutionary origin (another key concept in comparative anatomy).

Synonyms
