Explain any three with the examples to support evidences in factor of evolution?
Answers
EVIDENCES OF EVO LUTON. ..........
(1) Vestigial organs :-
The ungenerated parts which has become useless during evolution process due to no use is called as vestigial organs.
e. g. - the human appendix (was used as tail in animals), the outer ear (earlier used for ear movement).
(2) Morphological evidence :-
Various similarities like structure of nostrils, and ear pinnae and thickly distributed hairs in body are seen in animals whereas similarities in characters like leaf shape, leaf venation, leaf petiole, etc. occur in case of plants. This indicates that there are some similarities in those groups and hence it proves that their origin must be same and must have common ancestors.
(3) Connecting links :-
Some plants and animals show some morphological characters by which they can be related to two different groups; hence they are called as connecting links. e.g. - peripatus is connecting link between annelid a and arthropods due to tracheal respiration and open circulatory system like arthropods and segmented body, thin cuticle and parapodia-like organ.
●Charles Darwin's theory of natural selection,
●Jean baptist Lamarck's principle of use and disuse of organs.
And many scientist's have done groundbreaking work in the fields of evolution.
