Detailed explanation-1: -fossils help us understand how biodiversity has changed through time. fossils help us understand how organisms are related. most organisms that lived in the past are now extinct. fossils provide evidence of mass extinctions.
Detailed explanation-2: -Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species.
Detailed explanation-3: -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-4: -In addition, scientists can roughly date fossils using radiometric dating, a process that measures the radioactive decay of certain elements. Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history.
