Detailed explanation-1: -Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures’. They are contrasted with ‘homologous structures’, which have a common origin.
Detailed explanation-2: -Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.
Detailed explanation-3: -Convergent evolution is the process in which two or more organisms independently acquire similar traits. It stabilizes environments because it means the same role can now be played by different organisms meaning if one of these organisms becomes extinct the environment is not deprived of an essential service.
