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: -Mass extinctions were first identified by the obvious traces they left in the fossil record. In the strata corresponding to these time periods, the lower, older rock layer contains a great diversity of fossil life forms, while the younger layer immediately above is depauperate in comparison.
Detailed explanation-3: -Although fossils represent dead remains of the organism, it does not always mean that the organism in question has become extinct. Fossils of organisms that can even be found today means that the organisms have been on the earth since a very long time.
