The principles of fossil succession and natural selection are connected to Rocks and fossil fuels respectively.
<h3>Define principle of Fossil Succession ?</h3>
A method for determining the relative age of a fossil is through fossil succession. It can put the fossils in chronological order by using the geological strata to identify the rock layers where they are located.
<h3>Principle of fossil selection .</h3>
