Question

What impacts were seen on the life of primitive man with the change in atmosphere?

Answer 1

Explanation:

The primitive atmosphere of earth was reducing atmosphere with little or no oxygen but was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen, and hydrogen. The UV and gamma radiations from Sun were the major sources of energy for chemogenesis as these radiations have energy quanta that can release electrons from atoms resulting in formation of highly reactive free radicals which in turn combined to form early organic compounds.
