When two or more distantly related species develop some structural or functional similarities since they are found in the same environmental conditions, the process is called convergent evolution. Here, the developed similarities may not be present in the ancestors of these species. For example, the presence of wings in birds (Aves) and bats (mammals) represents convergent evolution. Therefore, the presence of similar features in two different species of mouse due to similar habitat conditions represent convergent evolution.
When two species of an organism habituating in two different locations with similar environmental conditions possess similar characteristics are said to evolve through convergence.
Such species have homologous structures due to which they have similar internal skeletal structure but their function and looks vary.
For example – wings of bat and limbs of human beings are homologous structure but their function and look are different from each other.
