Question

Which one of the following describes correctly the homologous structures:

• A. Organs with anatomical similarities, but performing different functions
• B. Organs with anatomical dissimilarities but performing same function
• C. Organs that have no function now, but had an important function in ancestors
• D. Organs appearing only in embryonic stage and disappearing later in the adult

Answer 1

Answer: (A)

Organs with anatomical similarities, but performing different functions

Answer 2

Homologous structures are anatomical features that have a common evolutionary origin, meaning they share a common ancestor. While they may have similarities in their structure, they can perform different functions in different species due to adaptation and divergence over time. These structures provide evidence of shared ancestry among different species.

So, the correct option is (A): Organs with anatomical similarities, but performing different functions.
