Answer:

1) The word ‘evolution’ was first mentioned in the book ‘The Origin of Species’ in 1859, by Charles Darwin. Darwin put forward the concept of evolution during his journey to the Galapagos Islands. 

2)Natural selection is an important mechanism of evolution. It states that the organisms that are able to survive and reproduce with the changing environmental conditions are selected by nature while the ones that cannot survive are eliminated.

3) Evolution mainly deals with the origin of life on earth. The conditions and the forms of life on earth were entirely different from what we see today.
