The main 2 observation which Lamarck made is:
<u>1. </u><u>Use and Disuse of Organ</u>
<u>2.</u><u> Inheritance of Acquired Characters.</u>
The Use and Disuse of Organ states that, only those character will last longer or pass on to next generation which are getting in use day by day. And, the organ will vanish if it not in use. Like, Tail in Human.
