Question

Which one of the following statements correctly defines convergent evolution?

• A. The development of similar characters/ states in different lineages that are related through a common ancestry.
• B. The convergence of many characters/ states in descents of the same lineage.
• C. The development of similar characters/ states in different lineages that are not directly related through a common ancestry.
• D. The development of different characters/ states in descendants of the same lineage.

Answer 1

The correct option is C The development of similar characters/ states in different lineages that are not directly related through a common ancestry.

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. For example, sharks and dolphins look relatively similar despite being entirely unrelated.

So the correct answer is option C
