Experimental Evidences of Chemical Evolution
Experiik mentally chemical theory of evolution performed by SL Miller and HC Uray in 1953.
He created electric discharge in a closed flask containing 
and water vapour at 800 C. He observed formation of amino acids. In similar experiments other the observed, formation of sugar, nitrogen bases, pigments and fats
The first non-cellular forms of life could have originated-3 billion years back. The first cellular form of life did not possibly originated till about 2 billion years ago because the conditions were non-biogenic at that time. This version of biogenesis, i.e., the first form of life arose slowly through evolutionary forces from non-living molecule was accepted by majority
