What is the evidence for evolution?

Sub-topics (containing additional resources):

Homology and analogy , Observations of evolution 


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.

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

Webcast: Fossils, genes, and embryos  Advanced
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.

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.
This article appears at SpringerLink.

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.

Similarities and differences: Understanding homology and analogy
This interactive investigation explains what homologies and analogies are, how to recognize them, and how they evolve.

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.

Evolutionary medicine
This excerpted chapter from Carl Zimmer’s book, The Tangled Bank, describes how evolutionary biology informs and advances medical science. Reprinted with the permission of Roberts and Company Publishers, Inc.

Sound trees
Students learn how spectrograms represent sound variation and then examine the sounds of owls for traits that might be useful in determining evolutionary relationships. They compare these traits to morphological ones and test their hypotheses.

Born to Run: Artificial Selection Lab
Students are introduced to the field of experimental evolution by evaluating skeletal changes in mice that have been artificially selected over many generations for the behavioral trait of voluntary exercise wheel running
