An example of this would be the similarities in behavior and morphology between [[bat]]s and [[bird]]s. Although superficially very similar, the two groups are considered by evolutionists to be only very distantly related (being grouped only within the clade [[Reptilia]]). Their similarities are therefore considered to be a result of evolution in response to nearly identical ecological niches and pressures. | An example of this would be the similarities in behavior and morphology between [[bat]]s and [[bird]]s.
