Title: A Peek At the Past: Fossil Patterns - Gradualism vs. Punctuated Equilibria
Url: http://www.indiana.edu/~ensiweb/lessons/peek.html
Creator: Alters, Brian J.
McComas, William
Publisher: Indiana University, Bloomington
Description: In this evolution lesson, two sets of simulated fossils (caminalcules) are provided as cutouts. Students arrange them on two time scales. One set produces a visual example of gradualism; the other shows punctuated equilibria. Students will learn the following concepts: some evolutionary change is rapid and discontinuous, and some change is gradual; fossil patterns can provide clues to the past; and speciation explains evolutionary branching and diversification.
