This Berkeley site offers a great overview of when the class appears in the fossil record.
A site from the University of California-Berkeley that details the process by which scorpions have evolved. Includes identifying characteristics of modern-day scorpions.
Understanding Biodiversity presents an overview of biodiversity, its importance and relevance to humans, all living things, and the Earth. It includes species pages and a template to engage and involve students in real-life data collection.
This extensive look at the arthropod provides enough information for any budding naturalist, but will also be interesting to one casually interested in insects, spiders, and crustaceans. The pictures are outstanding, and the writing is accessible and fun to read. Several interactive activities hold the reader's interest throughout the site.
Evolution can be supported by the lines of evidence which are presented in this resource. Recognize these lines: fossil evidence, homologies, distribution in time and space, and evidence by example.
Students explore the relationship between living things and their environment, and how the environment can impact a species' ability to survive, while referring to the text to ask and answer questions.
This video from Kentucky's Last Great Places shows how the Green River has remained unusually clean and why it is home to several endangered aquatic species.
In this tutorial students can learn the definition of species, how new species evolve, and the processes that can cause new species to arise. At the end of the tutorial students can take a quiz to evaluate what they learned about speciation.

Learn about the evolutionary process of sexual selection, a specific form of natural selection. [12:09]
This video segment from Evolution: "Great Transformations" illustrates the differences between the skeletons of a chimpanzee (a knuckle-walker) and a human (a biped).
What is evolution? This thorough site provides the basics of evolution focusing on the history of life, processes of evolution, microevolution, macroevolution, and more.
