Solution
0rigin of life on earth:
(i)Modern scientists refer to the origin of life as a kind of chemical reaction, which first generated complex organic molecules and assembled them.
(ii)This assemblage was such that they could duplicate themselves converting inanimate matter into living substance. The record of life that existed on this planet in different periods is found in rocks in the form of fossils.
(iii)The microscopic structures closely related to the present form of blue algae have been found in geological formations that are much older than these were some 3,000 million years ago. It can be assumed that life began to evolve sometime 3,800 million years ago.
