Detailed explanation-1: -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.
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: -Scientists who study fossils are called paleontologists (Pay-lee-en-TOL-oh-jists). Paleontologists compare fossils to find clues about early organisms and how they lived. Fossils can show how organisms evolved over very long periods of time.
Detailed explanation-4: -The fossil record is made up of all the fossils that have been found, along with their relative ages. Scientists can look at patterns in the fossil record to understand the history of life on Earth. For example, the fossil record shows us that there has been an overall increase in the complexity of organisms over time.
