Palaeozoology
40 - The coaservates which acquired nucleoproteins became first cellular organisms and their parts later became modified during the course of time due to chemical changes in the nucleic acid is the view of the scientist:
Oparin
41 - The hard Liithosphere was studded with volcanic eruptions pouring out hot lava. The Nitrogen and Carbon Atoms of atmosphere formed nitrides and Carbides respectively by reacting with metallic atoms of lava. The hot water vapours of atmosphere and carbides reacted to form Methane and water vapours and metallic nitrides reacted to form Ammonia.
