Answer:
YES!!!
Step-by-step explanation:
The principle of fossil succession helps scientists identify time periods, since particular fossils are unique to certain periods in Earth’s past.
The theory of evolution states that organisms change, or evolve, through time, and this helps geologists understand that different organisms would be found in different rock layers.
Index fossils are indicative of a certain period of time. If geologists find the same index fossil in various locations, they can correlate the respective rock layers.
Fossils give evidence of environmental conditions in the geologic past.
