Abstract

I present a framework for ecology and evolution laboratory exercises using artificial caterpillars made from modeling clay. Students generate and test hypotheses about predation rates on caterpillars that differ in appearance or “behavior” to understand how natural selection by predators shapes distribution and physical characteristics of organisms.
