Convergent evolution is a different phenomenon than evolutionary relay and parallel evolution.
CONVERGENT EVOLUTION
This is when two totally different species develop similar traits. They have come up with the same solution to a problem but from different directions. It's not a conscious choice to develop an eye or a way of hearing.
Convergent evolution
Another interesting phenomenon is called convergent evolution whereby different species of different ancestry come to resemble one another closely because of adaptation to similar environments.
Convergent Evolution: The development of similar structures in organisms that do not share recent common ancestor (e.g. eyes of squid and humans). Comparedivergent evolution; see also evolution.
convergent evolution The development of similar structures in distantly related organisms as a result of adapting to similar environments and/or strategies of life.
