How is the “principle of fossil succession” used in correlating rock layers from place to place?
A. Since life forms evolve from complex to simple over time, older rock strata will have relatively complex versions of life forms than younger layers.
B. Since life forms evolve from simple to complex over time, older rock strata will have relatively complex versions of life forms than younger layers.
C. Since life forms evolve from simple to complex over time, older rock strata will have relatively simple versions of life forms than younger layers.
D. Since life forms do not change in complexity over time, all rock strata will have relatively similar versions of life forms.
