Question : List three factors that provide evidences in favour of evolution in organisms and state the role of each in brief.

Answer»

Solution :Three factors that provide EVIDENCES are:
(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.
