The whale fin and the human hand are homologous structures.

Whereas human beings have bones such as the humerus (upper arm), ulna and radius (forearm), carpals (wrist bones), metacarpals (hand bones), and phalanges (fingers), these features appear as similar bones in form in the. Structures that are similar in different species of common ancestry. What is a homologous structure, and what is its example? Web homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor.
