A closer look at a classic ring species: The work of Tom Devitt
The Ensatina salamander has been extensively investigated because it is a ring species — a species that demonstrates how geography and the gradual accumulation of genetic differences factor into the process of speciation. Biologist Tom Devitt continues the more than 50 years of Ensatina research by applying new genetic techniques and asking new questions about this classic evolutionary example. |

Evo in the news: The new shrew that's not
This news brief from March of 2008 describes scientists' discovery of a new mammal species, a giant elephant shrew. Though elephant shrews resemble regular shrews, recent genetic evidence suggests that elephant shrews actually sprang from a much older (and perhaps more charismatic) branch of the tree
of life - the one belonging to elephants and their relatives. |

Evo in the news: When it comes to evolution, headlines often get it wrong
Newly discovered fossils are prompting some scientists to consider a minor revision of the relationships shown on the human family tree. This news brief from September 2007 clarifies the occasionally misleading news coverage of the story. |

Great Fossil Find
Students are taken on an imaginary fossil hunt and hypothesize as to the identity of the creature they discover. Students revise their hypotheses as new evidence is "found." |

History of evolutionary thought
In this section, you will see how study in four disciplinary areas — Earth's history, life's history, mechanisms of evolution, and development and genetics — has contributed to our current understanding of evolution. |

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. |

Nature of science
Understanding how science works allows one to easily distinguish science from non-science. Thus, to understand biological evolution, or any other science, it is essential to begin with the nature of science. |

Sequencing Events
Students attempt to sequence and create a story around a series of cartoon frames to serve as the basis for a discussion about how decisions are made and how arguments are constructed. |
