Detailed explanation-1: -Convergent evolution is when organisms that may not be closely related, converge to have the same endpoint. For example, this is often due to animals and anatomical um aspects. So for example, ducks and beavers both have webbed feet, yet they are not closely related. This could be an example of convergent evolution.

Detailed explanation-2: -Examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution, but homologous structures do not.

Detailed explanation-3: -Ducks and beavers are not related, but both have webbed feet due to living in a watery environment. With common ancestors, deer and elk in the US live in many of the same environments, but have grown to be different species.

Detailed explanation-4: -Some Other Examples of Convergent Evolution Streamlined body shape of dolphins, sharks and (extinct) ichthyosaurs. The evolution of echolocation in whales and bats. The paired shell shape of bivalve mollusks and brachiopods. The silk producing ability of spiders, silk worms, silk moths and weaver ants.

Detailed explanation-5: -Unrelated herbivores and carnivores have adapted to marine and freshwater environments. The flipper forelimbs of marine mammals (cetaceans, pinnipeds, and sirenians) are a classic example of convergent evolution.
