<p>Divergent evolution: when closely related species develop different phenotypes and traits from one another. Convergent evolution: when species develop similar features but are not closely related. Parallel evolution: when related species develop similar adaptations at the same time but are physically separated from one another.</p> Signup and view all the answers
