Expodentially is the correct answer
Answer: Fossil records help provide clues to the history of Earth's organisms. They've have given scientists clues needed to determine a present day organism's ancestry by comparing them with fossils. Fossil records also show that life has evolved from simple to complex; for example, fossils deeper into the ground (older ones) are much more simple than the ones at the top (newer ones), again supporting the idea of evolution. Fossils additionally show us how behaviors have evolved, how long individuals lived, and how features evolved over time.

With fossils, scientists can use carbon dating to determine the approximate age of whatever fossil they have.
