Which of the following pair of evidences indicates the common ancestry?

• A. Homologous organs&analogous organs
• B. Homologous organs & vestigeal organs
• C. Analogous organs & vestigeal organs
• D. Both $\left(A\right)$ and $\left(C\right)$

Answer 1

Answer: (B)

Homologous organs have common or same origin, which perform different or sometimes same functions in different organisms. The phenomenon is called homology, which indicates common ancestry. Vestigeal or rudimentary organs are non-functional, less developed, which were well developed and were functional in their ancestors. This also indicates common ancestry.
