Question

Which are accurate descriptions of comparative anatomy? Select three options.

may or may not include studies of structures with the same function
only involves studies of structures that are on the outer surface of the body
compares the structures of organisms from different species
always supports the concept of a recent common ancestor
includes studies of homologous, vestigial, and analogous structures

Answer 1

Correct choices:
- may or may not include studies of structures with the same function
- compares the structures of organisms from different species
- includes studies of homologous, vestigial, and analogous structures

Brief why: Comparative anatomy examines similarities and differences in body structures across species, including homologous (shared ancestry), analogous (similar function, different origin), and vestigial structures. It is not limited to outer structures, and it does not always indicate a recent common ancestor (analogous traits arise by convergent evolution).
