What is a homogeneous structure and what are some examples

A homologous structure can be described as structures present in similar and different species. These structures might not perform the same functions but are similar because they might have a common ancestor in the past.

An example of a homologous structure is the arms of a human and the wings of a bat. Although the arms of a human and the wings of a bat do not perform the same function yet they do have similarities because they have a common ancestor in the past.
