A) A vestigial structure in species A can be homologous to a functional structure in species B.
B) A vestigial structure in species A can be analogous to a functional structure in Species B.
C) A vestigial structure in species A is likely an example of convergent evolution with a structure in species B.
D) A vestigial structure in species A did not have a function in past ancestors.

Question

Quizplus · Accepted Answer

Vestigial structures are remnants of structures that were functional in the ancestors of a species but are no longer fully functional or have lost their original function in the species in question. When a vestigial structure in one species is homologous to a functional structure in another species, it indicates that both species share a common ancestor in which the structure was functional. This is why option A is correct.
