Abat wing an alligator leg, and a human arm and homologous structures. how does the presence of a homolous structures support one aspect of the theory of evolution?

Homology in bat wings, alligator leg, and a human arm represents their divergent evolution from common ancestor.

Explanation:

Homologous organs share a common basic structure but are adapted to perform different functions according to the need of organisms. Wings of bats (flying mammal), leg of alligator (reptile) and human (terrestrial mammal) arm share common basic developmental plan but are adapted to serve in flight, movement and holding things respectively.

Presence of homologous organs in these organisms from different group represents their evolution from a common ancestor. This means that bats, human, and alligators should have a common ancestor. Divergent evolution of the descends from the common ancestor must have given rise to homologous structures.
