Fossils provide evidence in favour of evolution. They establish evolutionary relationship by providing missing links.
Age of fossils can be determined by the folloeing ways :-
1. Relative method
Fossils found closer to the surface are more recent than those in depperlayer.
2. By detecting the ratios of different isotopes of the same element in the fossils material.
