Fossils are an importamt part of the study of human evolution
When a plant or animal dies its body is acted upon by various forces of nature like wind, air; With time body decomposes and gets covered by layers of soil in millions of years
Due to increasing pressure with every layer of soil getting added it creates an impression of the body while it further decays, Even it is acted upon by hot temperature inside
So even after millions of years of extinction of a species we can study about it looking at its impression in soil known as Fossil
one of the ways is
1) C-14 Carbon Dating
Which involves looking at the amount of C-14 deposits in the fossil and determining its age

bcz fossils helps in understanding organ structures that r no longer alive. There r 2 components to this estimation, 1 is relative, if we dig into the earth and start finding fossils, it is reasonable to suppose that the fossils we find closer to the surface is more recent to the fossils we find deeper. 2 is by dating fossils , by detecting the ratios of different isotopes of the same element in the fossil material.
