Question

why are fossils considered important in the study of evolution

Answer 1

Fossils are used importantly in the study of the Laws of Fossil Succession, according to which - 

1. Fossils represent the remains of once-living organisms.

2. Most fossils are the remains of extinct organisms; that is, they belong to species that are no longer living anywhere on Earth.

3. The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time.
