You are comparing three species (A, B, and C)

and you face a dilemma. Morphologically, species A

and B are very similar, but they are both diff erent from

species C. However, you have sequenced some genes in

all three and the gene sequences indicate a high degree

of similarity between species B and C. How would you

resolve this situation?

Wiley · Answer 1

The species A and B are analogous species and the species B and C are homologous species.

Explanation:

Analogous species are the species with similar morphology but different anatomy or the line of evolution.

Homologous species are the species having similar anatomy but different morphological features due to similar line of evolution.

Although morphologically similar, B and C share different lines of evolution. But A and B share same line of evolution. So they are homologous species even when they are morphologically different.
