Explain giving an example how the following provide evidences in favour of evolution in organisms.
(I) homologous organs
(ii) fossils
Answers
Answer:
homologous organs provide evidences about the body structure of primitive animals who have Kick the bucket/died a long ago.
ex.structure of flying dinasrous
Fossils provide a lot more evidences.
Answer:
a) Homologous organs are those organs which have the same structure and embryonic origin but perform the different functions. For example, forelimbs of whale, bat, deer, rabbit have the same structure but are modified in different ways to perform locomotion in different ways. Such kind of structures give rise to divergent evolution.
