The Understanding Evolution site provides evidence for evolution in biogeography utilizing relative dating, geography, and plate tectonics.

The Understanding Evolution website for teachers provides common examples of evolution, especially by artificial selection.

A strong, comprehensive look at the evolution of mammals. Includes factors such as changing geologic structure of the earth and the different types found on different continents.

This online chapter of a book studying biodiversity and conservation explores the evolution of mammals, from the extinction of the dinosaurs to the evolution of humans.

A module explaining how two different organisms can possess similar traits by sharing a common ancestor(homology) or due to convergent evolution(analogy).

A great lesson plan using the Scopes Trial as the basis of examining discussion about evolution. Included are student activities as well as links to additional information.

Explore this concise article detailing Charles Darwin's Theory of Evolution and follow with discussion questions.

Find out how Dr. Carl Woese used RNA to develop the tree of life.

As part of a larger online exhibit answering the question, What is evolution, this site examines the specific theory of evolution with immediate attention given to exploring and defining morphs.

The tutorial explores adaptation. Topics examined are evolution, co-evolution, variation within species, and mutation. Definitions, examples, and pictures on the concept are included.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

This lesson plan involves comparison of amino acids to create a phylogenetic tree of primates. Students will also use other species information to draw conclusions about evolutionary relationships.

This site explores what Hardy-Weinberg Equilibrium is, and how teachers can explore this topic in their classrooms. Content includes background information on this topic, as well as numerous learning activities.
