The Arthropod Story is an introduction to the wonderful world of arthropods and their evolution over time. They have a long and successful history that can be traced from the Cambrian Period, over half a billion years ago, to the present day.
Arthropods represent a major success story whether you look at their diversity, numbers, adaptability, or structural functionality. However, the same arthropod body plan that has produced such stunning success has limited arthropod evolution in other ways. The breathing and circulatory systems, exoskeleton, and molting may work well for small arthropods, but these same traits place severe limits to size.
This look at the arthropod story enables students to learn a number of evolutionary concepts. Students will learn much about the long history of the arthropods and have opportunities to think about arthropod evolution in terms of both opportunities and constraints. In the end, the big message is that all living things inherit both possibilities and limitations, and "survival" is often of the "fit enough."
