The preserved remains of animals or plants or other organisms from the distant past are called fossils. These fossils tell us about many extinct animals and also give insights into how the evolution could have taken place.

Evolution is the successive alteration in inherited characteristics over an extensive span of time, typically over generations.

Evolution relies on genetic variation in a population which affects the physical characteristics of an organism. Certain physical characteristics may give advantage to the individuals which can be transferred to their offspring.
The evidence of evolution is one of the fundamental keystones of modern biological theory. It is the only way which can prove all the proposed theories of evolution.
We have a number of evidences to prove the biological evolution namely fossils, comparative anatomy and embryo development pattern.
