Evolution: Part 3: Comparative Anatomy/Biochemistry and Analogous Structures

Question 1

Comparative Anatomy

Answer 1

Organisms that have similar anatomical structures are related to each other and share a common ancestor.

Question 2

Vestigial Structures

Answer 2

Are evidence that the anatomy of animals has evolved.

Question 3

Analogous Structures

Answer 3

• Convergent Evolution

- Structure with the same function but different structure.

Question 4

Homologous Structure

Answer 4

• Same Internal Structure

- The presence of Homologous Structure is evidence of common ancestry.

Question 5

Comparative Biochemistry

Answer 5

Organisms that have common ancestor will have common biochemical pathways.
Example: Humans and Mice
