[Free Registration/Login may be required to access all resource tools.] Meet Charles Darwin and his theory of evolution and natural selection. Understand why adaptations are important.

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...

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.

Examine Charles Darwin's voyage on the HMS Beagle and his ideas about evolution and natural selection.

Investigate how selection pressures and natural selection influence populations growth with this computer model. Understand how a population changes when selection pressures are in conflict. Perform the virtual lab to see what happens to...

This page has a Java simulation that demonstrates allele frequency and natural selection. Choose various numbers for this simulation and run the experiment.

These pages are part of a site called Evolution that accompany a textbook by the same name. Mark Ridley is the author. This section has an advanced discussion of determining allele and genotype frequencies using the Hardy-Weinberg ratio.

You are a bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the effects of natural selection. (Free usage is...

Teach aliens about evolution as you play this game, and review your own understanding in the process. Topics covered include evolutionary mechanisms, evidence of evolution, natural selection, reproductive isolation, population genetics,...

A comprehensive description of the papers on Natural Selection published by both Darwin and Wallace in 1858. Includes full copy of Wallace's paper, 'On the Law which has regulated the Introduction of New Species.' Also includes...

Learners are introduced to the concepts of digital organisms and digital evolution. They learn about the research that digital evolution software makes possible, and compare and contrast it with biological evolution.

Evolution, natural selection, sexual selection, coevolution, convergent evolution, mimicry, and coloration, are the topics examined in this thorough site. Assess your comprehension of the material presented by delving into the learning...

A learning exercise and notes regarding the basics of evolution and natural selection.

Students are introduced to the concepts of evolution by natural selection and digital evolution software. They learn about the field of evolutionary computation, which applies the principles of natural selection to solve engineering...

A hypothetical scenario is introduced in which the class is asked to apply their understanding of the forces that drive natural selection to prepare a proposal along with an environmental consulting company to help clean up an area near...

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...
