Detailed explanation-1: -Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record.
Detailed explanation-2: -The fossil record provides snapshots of the past which, when assembled, illustrate a panorama of evolutionary change over the past 3.5 billion years. The picture may be smudged in places and has bits missing, but fossil evidence clearly shows that life is very, very old and has changed over time through evolution.
Detailed explanation-3: -Some fossil organisms are transitional forms between groups of organisms. Fossil organisms often share physical similarities with living organisms. All fossils contain intact DNA that can be sequenced. Fossil ages can often be determined by testing nearby rocks.
Detailed explanation-4: -The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
