- If you can find many transitional fossils for a species showing how it changes over time, what type of evolution did that species most likely experience?
- You are studying the development of a set of species. Above are two prospective charts of their evolution. Correctly match the charts to the type of evolution.

- Why is it difficult to study evolution using only fossils? Choose all correct answers.
- Imagine you are a paleontologist that specializes in stratigraphy. Stratigraphy is determining the age of a fossil based on the "layer" of stone or sediment that it is found in.…
- Stromatolites are formed when layers and layers of film-forming bacteria collect sediment and turn into a fossil. Stromatolites are some of the oldest fossils ever, with some be…
