A site from the University of California-Berkeley on the sea-scorpion, an extinct arachnid. Shows evidence of evolution within the arachnid family.

The Evolution and the Nature of Science Institute offers lesson plans that investigate the vestigial organs in such a way as to better explain their imperfections as proof of evolution rather than the result of "intelligent design."

Through informational text, online lab activities, virtual simulations, and video clips, students study the concepts of biological evolution.

Are nature's complex forms evidence of "intelligent design"? In this Evolution essay, biologist Kenneth Miller explains how the processes of evolution account for complex structures such as the human eye.

To look at the evolution of modern bird feathers, we must start a long time ago, with the dinosaurs from whence they came. Carl Zimmer explores the stages of evolution and how even the reasons for feathers have evolved over millions of...

This virtual lab uses stickleback fish and fossil specimens to study evolutionary processes and teaches students skills of data collection and analysis.

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.

Understand the processes behind the nature of science.

Good discussion of both sides of the debate over the origins of birds. Presents the recent evidence that seems to lean in the direction of the pro-dinosaur ancestry argument.

This resource provides graphics, as well as explanation, of the remains of Homo habilis.

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

This interactive timeline provides information on the big bang as well as other major events of universe evolution. It also provides predictions about the universe's future.

This site from BioWeb Evolution was originally created as a ThinkQuest entry, and it has some good basic information about evolution. This page is on fossils and geologic time.

The only way to see the prehistoric cave paintings at Chauvet-Pont-D' Arc, France is to take the virtual tour offered here. Learn about the discovery of the caves and the archaeological evidence found that allows great insight into the...

A dynamic archive of information on digital morphology and high-resolution X-ray computed tomography of biological specimens.

Research continues to discover evidence left behind by prehistoric man. Discover the climate effects on human evolution and explore how the adaptable survived. The Asian and East African Research Projects in Kenya are described. You,...

The resource allows learners to read the book online for free. A group of experts explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative...

Evidence from the fossil record is used to support bird evolution from small carnivorous dinosaurs. In the student module, feathers, behavior, and skeletal structure are examined in an interactive lesson designed to impart a complete...

Present evidence suggests that blue-green algae, and possibly other primitive microbial forms of life, were flourishing 3 billion years ago. This brackets the origin of life to within one billion years. Learn more here about...

Find the human ancestor you are interested in and click on it either in the timeline or the list below for more details. Each fossil or reconstruction pictured includes links to more details about it.

Discover how birds descended from dinosaurs. Learn about the evidence scientist are uncovering to find out about the origin of birds. Throughout the video, there are embedded quiz modules that test students' understanding. [18:59]

Explore the dimensions of America's rich history by taking a detailed look at objects from our past. Examine stories, important moments, and the evolution of the American people via primary documents, photos, and other artifacts.

Travel through Earth's history to learn about the Oligocene time period, which is characterized by the appearance of most of the living families of mammals.

Learn about several different forms of evolutionary evidence.
