Answer:
The correct answer is homologous structures.
Explanation:
Charles Darwin is known for his ideas on evolution that species evolve by natural selection and all species have evolved from a common ancestor. His theory is well supported by piece of evidence including morphological, behavioral, embryological and anatomical features.
Anatomical features like homologous structures which show the similarity of bones among different species but performing different functions well support the theory of evolution that all species have diverged from a single common ancestor.
Thus, homologous structures are the correct answer.
