Verified by Experts

Three factors/ evidences and their roles.
(i) Analogous organs : Organisms with similar looking organs may have different origin.
(ii) Homologous organs : Organisms with apparently different looking organs may have similar origin.
(iii) Fossils : Allow us to make estimates of how far back evolutionary relationships go. Fossils when chronologically arranged help in tracing the evolutionary history of an organism.
