<P> According to the competitive exclusion principle , species less suited to compete for resources should either adapt or die out , although competitive exclusion is rarely found in natural ecosystems . According to evolutionary theory , this competition within and between species for resources is important in natural selection . However , competition may play less of a role than expansion among larger clades ; this is termed the ' Room to Roam ' hypothesis . </P>
