Question

question 7 of 20 : select the best answer for the question. 7. if two organisms possess similar structures that serve similar functions but dont possess a common ancestor that shared that structure, then the structures are classified as
a. vestigial.

b. homologous.

c. analogous.

d. morphologies.

mark for review (will be highlighted on the review page)

Explanation:

• Option A: Vestigial structures are remnants of structures that had a function in an ancestor but are now reduced or non - functional, so A is incorrect.
• Option B: Homologous structures are similar due to common ancestry, but the question states no common ancestor for the similar structures, so B is incorrect.
• Option C: Analogous structures are similar in function and structure but do not come from a common ancestor (they are a result of convergent evolution), which matches the description in the question.
• Option D: Morphology is the study of the form and structure of organisms, not a term for classifying such structures, so D is incorrect.

Answer:

C. analogous.
