Convergent evolution

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. It is the opposite of divergent evolution, where related species evolve different traits. On a molecular level, this can happen due to random mutation unrelated to adaptive changes; see long branch attraction.

Evolution of two or more different lineages towards similar morphology due to similar adaptive pressures. Examples of convergence are: fins or fin-like structures in fish, cuttlefish and whales; extreme similarity in alarm calls by five small birds; endothermy in dogs and ducks, wings of butterflies and birds.
