Found 13 resources for the concept: Scientists use experimental evidence to study evolutionary processes
 | Artificially Selecting Dogs
Students learn how artificial selection can be used to develop new dog breeds with characteristics that make the dogs capable of performing a desirable task.

 | 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.

 | Angling for evolutionary answers: The work of David O. Conover
Human activity has certainly affected our physical environment - but it is also changing the course of evolution. This research profile follows scientist David O. Conover as he investigates the impact of our fishing practices on fish evolution and discovers what happened to the big ones that got away.

 | 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 enough 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.

 | 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.

 | 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.
This lecture is available from Howard Hughes' BioInteractive website.
