The first living beings were prokaryotes like bacteria. They were single-celled. The nucleic acid core consisted of naked DNA. These living beings were present in the environment of the soupy sea having abundant organic molecules. Nutritionally they were chemo heterotrophs. They absorbed the organic materials from outside both for body building and liberation of energy. Respiration was anaerobic since free oxygen was absent in the environment.

The origin of life on earth has been because of chemical evolution. It can be justified by the Statement.
1 Every organism is a special creation of god, hence there is no scope for evolution of one form of life from another
2 Meteorites falling on earth have been found to contain a number of laevorotatory amino acids as are found in living beings
3 Torrential rains falling on earth for years brought \(\mathrm{N}_{2}, \mathrm{CH}_{4}, \mathrm{NH}_{3}, \mathrm{CO}_{2}, \mathrm{H}_{2}\) etc. into sea water where they reacted in presence of UV rays to form sugars, purines, amino acids, pyrimidines etc
4 Frothing appeared in nutrient broth kept in open after some days of sterilization, while no frothing appeared in closed jar

S.L. Miller created electric discharge in a closed flask containing.
1 \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapour at \(80^{\circ} \mathrm{C}\)
2 \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapour at \(800^{\circ} \mathrm{C}\)
3 \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapour at \(8000^{\circ} \mathrm{C}\)
4 \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{2}\) and water vapour at \(800^{\circ} \mathrm{C}\)
Explanation:
The experiment used water \(\left(\mathrm{H}_{2} \mathrm{O}\right)\), methane \(\left(\mathrm{CH}_{4}\right)\), ammonia \(\left(\mathrm{NH}_{3}\right)\), and hydrogen \(\left(\mathrm{H}_{2}\right)\).

The following diagram represents experiment done by
1 Pasteur - Biotic evolution of life
2 Darwin - Natural selection
3 Miller - Chemical evolution of life
4 Haldane - Chemical evolution of life
Explanation:
The Miller's experiment is chemical evolution of life used water (H20), methane (CH4), ammonia (NH3), and hydrogen (H2). So, the theory of chemical evolution was based on the experiment of Miller and Urey at 800 degree Celsius
