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. |

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. |

Evo in the news: Musseling in on evolution
This news brief, from September 2006, reviews a recent case of evolution in action. In just 15 years, mussels have evolved in response to an invasive crab species. Find out how biologists uncovered this example of evolution on double time. |

Webcast: From butterflies to humans
In lecture four of a four part series, evolutionary biologist Sean Carroll uses the developmental genetics of insects to explain how old genes can learn new tricks and how this can help us understand human evolution.

Webcast: Selection in action
In lecture two of a four part series, evolutionary biologist David Kingsley discusses how just a few small genetic changes can have a big effect on morphology, using examples from maize, dog breeding, and stickleback fish.
