In evolutionary biology, convergent evolution is the process by which two organisms or taxonomic groups have a character in common due to independently adapting to a similar environment or niche, not by homology.
An example of this would be the similarities in behavior and morphology between bats and birds. 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.
