Detailed explanation-1: -Examples of homologous structures include the wings of bats and the hands of human, as both these types of animals have evolved from a shared ancestor, but the aforementioned structures have very different functions.

Detailed explanation-2: -An example of homologous structures is the forelimbs of humans and bats. The forelimbs of both humans and bats have the same fundamental skeletal structure, derived from the same embryonic origin, and evolved from the same structures. Both of them are of mammalian origin. However, their forelimbs are used differently.

Detailed explanation-3: -Did you know that humans, birds, and bats have the exact same types of bones in their forearm? These organisms share the same forearm bones because they all evolved from a common ancestor. Human, bird, and bat forearm bones include the humerus, ulna, radius, carpals, metacarpals, and phalanges.

Detailed explanation-4: -Thus the forelimbs of such widely differing mammals as humans, bats, and deer are homologous; the form of construction and the number of bones in these varying limbs are practically identical, and represent adaptive modifications of the forelimb structure of their common early mammalian ancestors.

Detailed explanation-5: -A great example of homologous structures are the wings of a bat and the arms of a human. Bats and humans are both mammals, so they share a common ancestry. Both a bat’s wing and a human’s arm share a similar internal bone structure, even though they look very different externally.
