Convergent evolution is a phenomenon whereby similar traits evolved independently in not closely related species, and is often interpreted in functional terms spines in mollusk seashells are classically interpreted as having repeatedly evolved as a defense in response to shell-crushing predators. Repeated adaptive radiations are evident when phenotypic divergence occurs within lineages, but this divergence into different forms is convergent when compared across lineages classic examples of such repeated adaptive divergence occur in island (for example, caribbean anolis lizards) and lake.
