Vertebrates are a group of related animals with a backbone.All vertebrates have basically the same eye structure.Therefore,the vertebrate eyes are
A) homologous structures.
B) vestigial structures.
C) analogous structures.
D) convergent structures.

Question

Quizplus · Accepted Answer

Homologous structures are anatomical structures that have the same evolutionary origin but may have different functions in different organisms. Since all vertebrates have a similar eye structure, it suggests that they share a common ancestor and that the eyes are homologous structures. Vestigial structures are structures that have lost their original function through evolution, which does not apply to the vertebrate eyes. Analogous structures are structures that have the same function but different evolutionary origins, which is not the case for vertebrate eyes. Convergent structures are structures that have evolved independently in different organisms to serve a similar function, which also does not apply to vertebrate eyes.
