Biological warfare and the coevolutionary arms race
The rough-skinned newt looks harmless enought but is, in fact, packed full of one of the most potent neurotoxins known to man. Find out how an evolutionary arms race has pushed these mild-mannered critters to the extremes of toxicity and how evolutionary biologists have unraveled their fascinating story.

Comic strip: Survival of the sneakiest
This comic follows the efforts of a male cricket as he tries to attract a mate, and in the process, debunks common myths about what it means to be evolutionarily "fit."

Evo in the news: Evolution in the fast lane?
Have humans, with all of our technological advances, exempted ourselves from further evolution? Perhaps not. This news brief, from February 2008, examines genetic research which suggests that human evolution may haved actually accelerated in our recent history.

Evolution and Antibiotic Resistance
Students learn why evolution is at the heart of a world health threat by investigating the increasing problem of antibiotic resistance in such menacing diseases as tuberculosis.
9-12 Classroom activity
Fire ants invade and evolve
Understanding the evolution of fire ants may help scientists control the spread of these pests, which have already taken over much of the U.S.!

9-12 Tutorial
Monarch/Viceroy Case
Students work in groups to develop a Darwinian explanation for the bright coloration of monarch and viceroy butterflies and the similarity in color patterns seen between the two species.
9-12 Classroom activity
Natural selection: The basics
Darwin's most famous idea, natural selection, explains much of the diversity of life. Learn how it works, explore examples, and find out how to avoid misconceptions.
This article is located within Evolution 101.

The Natural Selection Game
This is a board game that simulates natural selection. It is suitable for an introductory biology class and for more advanced classes where you could go into more detail on important principles such as the role of variation and mutation.
9-12 Classroom activity
Using Magnetotactic Bacteria to Study Natural Selection
In this lab students observe bacteria that are able to orient themselves using the Earth's magnetic field, demonstrating that living organisms possess incredible adaptations which enable them to survive.
9-12 Classroom activity
Viruses and Host Evolution
Students learn about natural selection in rabbits by observing the effects of a virus on the Australian rabbit population.
