Evolution --- What is the evidence for evolution?

Resources:

Lines of evidence: The science of evolution
The theory of evolution is broadly accepted by scientists — and for good reason! Learn about the diverse and numerous lines of evidence that support the theory of evolution.
15 evolutionary gems
This succinct briefing describes 15 examples drawn from recent research that demonstrate evolutionary theory’s power to explain natural phenomena, along with some of their supporting lines of evidence--from whale fossils to the latest in genetics.
This resource is available from Nature magazine.

Darwin's "extreme" imperfection?
Darwin used the words "extreme imperfection" to describe the gappy nature of the fossil record - but is this really such a problem? This article delves into the topic of transitional fossils and explores what we have learned about them since Darwin's time.

Webcast: Fossils, genes, and embryos
In lecture three of a four part series, evolutionary biologist David Kingsley examines the original objections to Darwin's theory and shows how modern evidence supports the theory.
This lecture is available from Howard Hughes' BioInteractive website.

Evo in the news: What has the head of a crocodile and the gills of a fish?
This news brief, from May 2006, reviews what is likely to be the most important fossil find of the year: Tiktaalik helps us understand how our own ancestors crawled out of the water and began to walk on dry land.

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.

Clair Patterson: Radiometric dating
Clair Patterson used radiometric dating to provide evidence that Earth (and the life on it) is ancient.

Wallace and Wegener: Biogeography
Alfred Russel Wallace's studies of species ranges and Alfred Wegener's conception of continental drift provide compelling evidence that much of a species’ present distribution can be explained by its evolutionary history.
