Correct answers:
- how different species have diversified over time
- the order in which different types of organisms appeared on Earth

Explanation: Fossil layers (stratigraphy) provide a relative timeline showing how species change and when groups first appear. The fossil record is incomplete and biased, so it cannot tell you exactly how many organisms were alive in a given period.
