The fossil Record

   The fossil record is incomplete because very few organisms were preserved as fossils. organisms tend to decay before becoming a fossil. Animals with hard parts are preserved more easily and geological processes may destroy fossils. Darwin believed that the fossil record showed the history of life on earth.The fossil record of all species is not complete because the circumstances for fossils to occur is very rare.
