Detailed explanation-1: -Convergent evolution: Convergent evolution occurs when two organisms that lack a recent common ancestor end up more and more alike as they adapt to a similar ecological niche. The organisms have convergent phenotypes, and their similar structural forms are called analogous structures (such as bird wings and bat wings).
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 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’.
Detailed explanation-4: -Explanation: Structures that are similar as a result of convergent evolution are referred to as analogous structures, such as the wings of beetles and birds. These animals do not share a common ancestor, and developed the trait for wings independent of one another.
Detailed explanation-5: -In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
