Question

Analogous organs arise due to:

• A. divergent evolution
• B. convergent evolution
• C. artificial selection
• D. genetic drift

Answer 1

The correct option is B convergent evolution

Divergent evolution:

Homologous organs have the same basic plan but perform different functions due to divergent evolution, where the organisms have a common ancestor.

Artificial selection:

Artificial selection is the breeding of plants and animals by man (using animal husbandry and plant breeding programs) to obtain offspring with desirable traits.

Genetic drift:

Genetic drift is the fluctuation in the gene frequency of a population.

Convergent evolution:

Analogous organs have different structural basic plans but perform the same function. This may be due to the fact that these organisms may have lived in the same environment hence their body parts have evolved to have the same type of functions. This is called convergent evolution.



Final answer:

d.convergent evolution
