Learn how Charles Darwin became one of the most influential scientists of all time with this short biographical video. [3:38]

This collection uses primary sources to explore the 1925 Scopes Trial. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

An active problem-based assignment that uses the Genbank database to teach the basics of molecular biology and molecular evolution

Mitch Sogin analyses the genes of a sponge in his search for the origin of animals. In order to sequence the genes, he extracts them from the cells. We see the threads of DNA in a test tube. He compares a similar gene found in all the sequences in the animals he tested. Over time small mutations occur in all genes. The more closely related the animals are, the more similar is the code in a shared gene. He created a family tree by comparing the number of changes in the code. The sponge was at the bottom because its gene had the fewest changes. [8:09]

The scientific fields of paleontology, embryology, anatomy, and genetics have all contributed to a new view of the evolution of the animal kingdom. [3:42]

We think that humans are at the top of the evolutionary ladder. But is being big, brainy, and fast the best design? Evolution has produced many animals with different approaches to life. Every animal is uniquely adapted to win at the game of survival. [3:50]

This series of images shows the work of biologist Karl Niklas on the adaptations and evolution of plants. From The Evolutionary Biology of Plants.

An interactive lecture that uses flash animations showing the researcher and their experiments that were used to develop the basic concepts in Mendelian genetics. Includes multiple choice questions students can answer in class.

Learn more about the theory that dogs evolved from wolves in this video from Nature. [5:03]

This colorful, interactive site demonstrates how fossils can be used to discover a range of information about the past. Topics include Past Lives, Paleoecology, Geologic History, and Biodiversity.

Students observe natural selection in action and investigate the underlying mechanism, including random mutation and differential fitness based on environmental characteristics. They do this through use of the free AVIDA-ED digital evolution software application.

Students engineer and evolve digital organisms with the challenge to produce organisms with the highest fitness values in a particular environment. They do this through use of the free Avida-ED digital evolution software application. The resulting organisms compete against each other in the same environment and students learn the benefits of applying the principles of natural selection to solve engineering design problems.

This video segment from Evolution: "Why Sex?" explores the "sweaty T-shirt experiment," which showed that humans may unconsciously be drawn toward a specific kind of genetic variation in a mate.

Video explains how mice, coyotes, and newts can show signs of evolution, even in a big city such as New York. [5:16] Includes a brief quiz and a list of additional resources to explore.

Video discusses the concept of evolution and the five processes that can cause it to happen. [5:24] Includes a brief quiz and a list of additional resources to explore.

Anusuya Willis explains how cyanobacteria, simple organisms that don't even have nuclei or any other organelles, wrote a pivotal chapter in the story of life on Earth. [4:14]

Laurence Moran discusses one of the most important mechanisms of evolution, Random Genetic Drift.

Bonnie Chen builds on students' prior knowledge of mutations to lead her class through a simulation of wading birds feeding. [14:02]
