Evolution of life shows that life forms had a trend of moving from
1 Land of water
2 Dryland to wet land
3 Fresh water to sea water
4 Water to land
Explanation:
Evolution of life shows a trend of moving from water to land .The early vertebrates were fishes lived in only water. Some fishes have attempted a change in their mode of life from aquatic to terrestrial and evolved into amphibians. Certain amphibians then transformed into the reptiles which are true terrestrial vertebrates. Some of the reptiles latter evolved into birds and than mammals.

According to theory of spontaneous generation:
1 Life was created by special creation
2 Life came from pre-existing non-living organic molecules
3 Life came from dead and decaying matter
4 Life came from another planet
Explanation:
The idea of spontaneous generation is an obsolete theory that states that living organisms can originate from inanimate objects. Other common examples of spontaneous generation were that dust creates fleas, maggots arise from rotting meat, and bread or wheat left in a dark corner produces mice.
