Detailed explanation-1: -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-2: -As pieces of once living things, body fossils are evidence of what was living where and when. Trace fossils are valuable because they “animate” the ancient animals or plants by recording a moment of an organism’s life when it was still alive.
Detailed explanation-3: -Fossils of any kind are useful in “reading the rock record, ” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.
Detailed explanation-4: -Fossils provide our only direct evidence for when life appeared on Earth. They are found in sedimentary rock, which is rock formed when fine particles of mud, sand, or dust entombed an organism before it can be eaten by other organisms.
