explain elvolution in detail

Explanation:
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.

Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.

"All life on Earth is connected and related to each other," and this diversity of life is a product of "modifications of populations by natural selection, where some traits were favored in and environment over others," he said.

Here, "fitness" refers not to an organism's strength or athletic ability, but rather the ability to survive and reproduce.
Darwin stated the evolution in his theory, the natural selection. It was:-
(i) The nature selects the organisms with characteristics that are superior to other.
(ii) Those organisms reproduce while the other perish, and forms individuals with variations due to the involvement of 2 different gametes.
(iii) This process continues and each time the individual formed have some major differences in characters to that of their ancestors.
(iv) After along time, the new individual produced is completely different from the ancestor and so a new species forms.
This is the process of evolution..
