. State the evidence we have for the origin of life from inanimate matter
Ans. An experiment conducted by Stanley L. Miller and Harold C. Urey in 1953 proved that origin of life take place from inanimate matter. They assembled an apparatus to create and early earth like atmosphere which was support to consist of gases like methane, ammonia and hydrogen sulphide but no, oxygen over water.
This was maintained at a temperature just bellow 100 C and sparks were passed through the mixture of gases to simulate lighting. At the end of a week, 15% of the carbon (from methane) has been converted to simple compounds of carbon including amino acids which make up protein molecule.
