Question

Being all mammals, whale, dolphin, bat, monkey and horse have some common trait, but they also show conspicuous differences. This is due to the phenomenon of

• A. Normalisation
• B. Genetic drift
• C. Convergence
• D. Divergence

Answer 1

The correct option is D Divergence

Homology refers to evolution of organisms in different directions from a common ancestry i.e., divergence. It leads to development of homologous organs that are adapted to perform different functions and have different appearance but share common basic structural plan and origin.

Divergent evolution is the accumulation of differences between groups, which can lead to the formation of new species, usually a result of diffusion of the same species to different and isolated environments.

So, the correct answer is 'Divergence'
