The forelimbs of a bat and a human are homologous structures.
The forelimbs of a bat and a human are considered to be homologous structures. Homologous structures are organs or structures that have the same evolutionary origin but may have different functions. In this case, both the bat's wing and the human arm have the same basic bone structure, consisting of a humerus, radius, and ulna. However, they have adapted to serve different purposes, with the bat's wings being modified for flight and the human arm primarily used for grasping and manipulation.
