What Can Fossils Tell Us About the History of Present-Day Organisms?
Fossil evidence can tell us how ancient and present-day organisms change over time.
Students explore 3 real fossils and a picture of a fossilized archaeopteryx and compare them to present-day organisms. They speculate about what the long-ago environment might have been like when the fossil organisms were alive. Finally, they use their knowledge of the mechanism of natural selection to discuss the fossils’ relationship to present-day organisms.
