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

These pages are from the Understanding Evolution website for teachers. They focus on homologous structures that organisms with common ancestors share.

A brief description of Charles Lyell and his work "The Principles of Geology" which includes the concept of uniformitarianism. A description of his views on evolution and a comparison to Charles Darwin.

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

Concise description of embryology as evidence for evolution, as used by Darwin.

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.

This site is a section part of a website that accompanies "Evolution," a textbook by Mark Ridley. Here he covers homologous structures, using them as evidence for evolution.

These pages are part of a site called "Evolution," that accompanies a textbook by the same name. Mark Ridley is the author, and in this section he discusses the evidence for evolution.

These pages are part of a site called Evolution that accompanies a textbook by the same name. Mark Ridley is the author. These pages offer an explanation of speciation using reproductive isolation and differences in phenotype.

Constructing phylogenetic trees may be a daunting task for students, but this lesson plan is a simulation of what molecular biologists must do to determine relationships. This plan is for students who have a good grasp of DNA structure...

Students develop their understanding of natural selection by analyzing specific examples and carrying out a simulation.

Viral genomes are the fastest evolving entities in biology, mainly because of their short replication time and the large quantity of offspring released per cell infected. Evolution occurs by several mechanisms: Random mutation,...

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. Fossils provide a record of organisms that lived a long time ago. They also...

This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

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.

Darwin's theory of evolution explains how species of living things have changed over geological time in order to survive in the changing environment. A link to a test is provided.

Find out how evolution happens due to chance events. Explore the bottleneck effect and founder effect.

The history of human evolution is described, from the first aquatic animals that developed the ability to walk on land and the pivotal organisms from then up to the present day. The author then goes on to make interesting predictions...

Divergent and convergent evolution are explained and their differences are highlighted.

Just 50,000-100,000 years ago, Earth was home to three or four separate human species, including our most famous cousins: the Neanderthals. New research has shown that Neanderthals were not the brutish, unintelligent cavemen that...
