A presentation on Darwin's theory of evolution and natural selection could be a good addition to your biology class. It provides general information about how animals adapt to their surroundings, as well as how organisms create more...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

How did Charles Darwin support his controversial theory of evolution with evidence? Use an excerpt from his 1859 work On the Origin of Species to reinforce the importance of making inferences within an informational text, and to...

Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Use the 5E model to learn about natural selection and selective breeding.

Explore natural selection by controlling the environment and causing mutations in bunnies.

[Free Registration/Login may be required to access all resource tools.] An introduction to Charles Darwin and his theory of evolution by natural selection is offered for students. Meet the writers who influenced Darwin to develop his...

Instructional module focusing on Charles Darwin's explanation of natural selection as the mechanism for evolution. Discusses how this force of natural selection promotes changes in species over time. Site also includes an interactive...

[Free Registration/Login may be required to access all resource tools.] Do you ever wonder why some birds are big like ostriches and some birds are small like robins? Or why a lion has a mane while a leopard has spots? In the 19th...

[Free Registration/Login may be required to access all resource tools.] Covers Darwin's theory of evolution by natural selection.

[Free Registration/Login may be required to access all resource tools.] The theory of evolution by natural selection means that the inherited traits of a population change over time. Inherited traits are features that are passed from one...

Practice exercise on natural selection. This is new content.

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

[Free Registration/Login may be required to access all resource tools.] Overview of the basic concepts behind evolution.

The concept of interdependence in an ecosystem and its effect on the evolution of populations is further explored through a model of a dam. Students build a dam in the middle of the field, dividing the ecosystem in half to illustrate the...

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.

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...

This resource presents extensive information for learning about and teaching evolution including an in depth course "Evolution 101", teaching materials, and a resource library.

[Free Registration/Login may be required to access all resource tools.] Explains how natural selection favors certain traits in a population so that the organism adapts to its environment, and that changes in the genes over time cause...
