Which of the following would involve looking at different structures of organisms and comparing how similar they are? a. vestigial structuresb. radiometric datingc. homologous structures

The correct answer is c. homologous structures.

Homologous structures are those which are similar in origin but dissimilar in function. The organs are made of the same bone pattern and structure. Origin of hooves in both horse and mountain goat have same structure but performing different functions as they live in different habitats. The homologous structures represent divergent evolution. Thus, we look at at different structures of organisms to compare  similarity.

The correct answer is option C, homologous structure

A homologous structure have similar anatomy and morphology though they have different functions. such as the arm of a human, the wing of a bird or a bat, the leg of a dog etc. All are different in function but share a common ancestry

while on the other hand vesitigial organs are the organs we acquired from our forefathers but are of no use to us such as appendix

Radiometric dating is the process of determining the age of the fossils based on the c14 content and its dating
