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

  1. Analogous organs: organisms with similar looking organs may have different origin.
  2. Homologous organs : organisms with apparently different looking organs may have similar origin.
  3. 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.
