Question

What evidence do we have for the origin of life from inanimate matter?

Answer 1

1. The British Scientist Haldane suggested that life must have originated from inanimate matter consisting of simple inorganic molecules such as methane, ammonia and hydrogen sulphide, etc., which were present on the earth soon after it was formed.
2. The evidence for the origin of life inanimate matter was provided by the experiments conducted by Stanley Miller and Harolde Curvey.
3. They assembled and apparatus to create an early earth atmosphere which was supported to consist of gases like methane, ammonia and hydrogen sulphide, ete, (but no oxygen), over water.
4. This was maintained at a temperature just below 100 C and electric sparks were then passed through the mixture of gases (to stimulate lighting) for about one week.
5. At the end of one week, it was found that about 15 percent of carbon (from methane) had been converted into simple compounds of carbon including, 'amino acid' which make up protein molecules found in living organisms.
6. This experiment from inanimate matter (or lifeless matter) like inorganic molecules.
