<h3>What is homologous evolution?</h3>
Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.
Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.
