what does fossils tell us about the process of evolution
Fossils tell us about the phases of evolution through which various species must have gone in order to sustain themselves in the competitive environment. They also tell us about the development of the structures from simple to complex forms in organisms.
Fossils also give an idea about the missing links between various species as well as about various common ancestors of later species. In addition, fossils give a clue to the divergent evolution. Even the record of extinct organisms can be obtained through fossil records. Based on the position of fossils in the layers of the Earth's crust, paleontologists can determine which animals predate other animals and which animals lived at the same time.
