Detailed explanation-1: -The fossil record provides evidence for when organisms lived on Earth, how species evolved, and how some species have gone extinct.
Detailed explanation-2: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.
Detailed explanation-3: -Paleontologists were able to detect the particular order in which these organisms have lived. For instance, simpler organisms inhabited older rocks and complex organisms were found in younger rocks. This finding has made them conclude that simple organisms have evolved into more complex organisms over time.
