Structures that look similar but do not share a developmental and evolutionary origin are called:
ADerived structures
BAncestral structures
CAnalogous structures
DHomologous structures
Answer & Solution
Correct answer: C. Analogous structures
1. Similarity of appearance is not by itself evidence of relatedness.
2. Homologous structures overlap both morphologically and genetically.
3. Structures that resemble each other without that shared basis are called analogous structures.
4. Only homologous structures support a claim of common ancestry.
