1.	Explain the theory of evolution and mention the proof supporting it.
Answer» 1. Theory of evolution: According to the theory of evolution, first living material was in the form of protoplasm which was formed in ocean. Gradually, it gave rise to unicellular organisms. Changes took place in these unicellular organisms which made them evolve into larger and more complex organisms. All evolutionary changes were very slow and gradual taking about 300 crore years to happen. Different types of organisms were developed as the changes and development that occurred in living organisms wefts all round and multi-dimensional. Hence, this overall process of evolution is called organizational and progressive. Variety of plants and animals developed from the ancestors having different structural and functional organization during the process of evolution.
