Analogous structures often develop through the process of evolution, rather than a close evolutionary relationship.

The correct answer is - convergent evolution.

Explanation:

The convergent type of evolution involves the process in which non-related organisms evolved independently and still develop similar kinds of traits or structures due to factors such as ecological or environmental conditions. This environmental condition could be an ecological niche or issues faced by the organisms which force them to adapt accordingly.

For example, dolphins and shark look similar but are different organisms. Analogous organs or structures arise due to the convergent evolution as they have different ancestry still shows structures similar to one another.
