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

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.

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.

[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...

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

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...

How does evolution really work? Alex Gendler sets the record straight on the finer points of evolution, including some common evolutionary misconceptions.

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

Explore the evidence of evolution with this interactive worksheet based off of NOVA's Evolution Lab. This resource is designed to be completed while playing through the Evolution Lab game and contains multiple choice and free response...
