Discovery School provides a lesson plan on evolution by having students make a timeline of the history of evolution. This timeline will have dates and, above or below the dates, will provide details about the people who have played major...

Through fossils scientists have been able to study the evolution of whales. Read this article to take a closer look at the details.

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.

A reference page containing information related to evolution. Topics discussed on the page is the theories, human evolution, evolutionary evidence, Darwin, and Earth's history.

Evolution is the change of inherited characteristics within a population over time through natural selection, which may result in the formation of a new species.

In this biology activity, students will be investigating evolution by "competing" for food like Darwin's finches might have competed. Each student group is given a different type of "beak" to work with and there are also different kinds...

A collection of video lectures dedicated to study Charles Darwin's legacy. The course was hosted at Stanford University. The lectures cover a broad range of topics from evolution vs. creationism, Darwin's life and work, social Darwinism,...

In this activity, you'll learn how to interpret images and maps in order to extract information about Darwin's trip to the Galapagos Islands. Links provided for a gallery of images and a worksheet.

Explore the work of Charles Darwin and the theory of evolution. This comprehensive resource includes information about Darwin's life in addition to the process of species evolution.

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.

This graphic from Ecology and Evolution of Darwin's Finches by Peter Grant presents data from the Galapagos Islands, showing that a severe drought put selective pressure on the population of Darwin's finches and resulted in a change in...

Discusses Lamarck's theory of evolution, which was developed before Charles Darwin's own theory, and how it fared over time. The core ideas in Lamarck's theory are described and his theory and Darwin's are compared. Lamarck's ideas...
