Detailed explanation-1: -Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Detailed explanation-2: -Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists reconstruct the evolutionary histories of present-day species.
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: -A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. This is especially important where the descendant group is sharply differentiated by gross anatomy and mode of living from the ancestral group.
