Question

how is life emerged in primitive earth .....any guess​

Answer 1

Answer:

Life emerged on primitive earth due to some environmental factors. Before millions of years, due to some environmental changes, some bio-chemical reactions occurred under the ocean which led to the formation of primitive ribosome and DNA. Thus, an unicellular organism formed.

It went on reproducing itself. Due to the reproduction, few variations occurred in each generation due to errors in DNA copying. This variations, after thousands of years formed another species which wasn't abled to reproduce with its pre-existing species naturally.

Thus, the life on Earth emerged.
