What concept states that "ancient life forms succeeded each other in a definite, evolutionary pattern and the contained assemblage of fossils can determine the geologic age of the strata"?

The correct answer is Principle of Faunal Succession.

Explanation:

This principle states that fossil remains occur over time and that this can be predicted.

This is established by observing that there are remains of fossilized fauna and flora found in sedimentary rocks, and they are found in all these rocks in any place, no matter where they are.

Then, analyzing this it is possible to determine the age of the rocks and strata found, depending on the flora and fauna that are fossilized on them, by determining when the sediments that conform to the rock were deposited.

Thanks to the study of flora and fauna, the entire age of the Earth can practically be studied since they are widely distributed throughout the planet throughout history.

And so you can study the climate throughout the life of the planet, the groups of plants and animals and the age of the rocks.
