A description of the process of evolution explaining the Hardy-Weinberg Principle and the mechanisms that cause it. Also the website contains links for lessons on simulation of the natural selection process in the classroom and how the...

Finches on the Galapagos Islands have evolved to exploit almost every possible niche. This diagram shows the range of food sources available on the island and the different beak shapes adapted to exploit each of them. Includes background...

Overview of the basic concepts behind evolution, such as gene variation and adaptations.[Free Registration/Login may be required to access all resource tools.]

This is a lesson designed by a biology teacher. In it, students use maps and evidence of island age, molecular genetics, morphology, and distance apart to determine how the islands came to be occupied by different species of lizards. It...

An online summary of the evolution of flowering plants at an advanced level. The text is supported by good illustrations and is followed by a quiz. This is a good review for exams.

The main concepts in Charles Darwin's theory of evolution are described, how natural selection works, and the ongoing criticism of evolution from Creationists.

With rising temperatures and seas, massive droughts, and changing landscapes, successfully adapting to climate change is increasingly important. For humans, this can mean using technology to find solutions. But for some plants and...

From the Evidence for Evolution Library at PBS, this is a short article about biogeography. The distribution of animals is one source of evidence for Darwin's descent with modification.

Get an overview of the process of microevolution.

The ways in which plants have adapted through evolution in order to survive in a desert environment are described in this article. Getting water and retaining water are key to their survival, including protecting themselves from animals...

In this photograph from Oxford Scientific Films, a horned bee attempts to mate with an Ophrys orchid, which has evolved to resemble a female bee.

Describes the seven characteristics that define life - cells, homeostasis, heredity, use of energy, reproduction, response to environmental stimuli, and evolution and adaptation.

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

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents...

In this video segment adapted from NOVA, animations of an asteroid hitting Earth are used to illustrate this widely accepted theory of dinosaur extinction and the resulting conditions that favored mammals.

Instructional module focusing on the early work of Charles Darwin. Discusses Darwin's key role in supporting and describing the theory of evolution as driven by natural selection. Site also includes an interactive practice quiz and links...

In this activity, students examine research on finches on the island of Daphne Major in the Galapagos Islands. The depth of the finches' beaks was measured before and after a drought. This data is displayed in graphs and students are...

In this simulation lesson, students investigate the role of natural selection and survival within a frog population living in a changing environment. Includes student handouts along with an assessment piece.
