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...

The chemical arsenal we have developed in an attempt to rid our homes of rodents and our crops of insects is losing its power. We have simply caused pest populations to evolve, unintentionally applying artificial selection in the form of...

[Free Registration/Login may be required to access all resource tools.] The creation of a new species is called speciation. Most new species develop naturally. But humans have also artificially created new breeds and species for...

This article allows students to recognize that the process of evolution by natural selection continues to change our world and ourselves, both despite and because of our best efforts to control it.

This entry identifies the defining characteritics of animal evolution, including adaptation, speciation, extinction, animal parternships and natural selection.

This animated description of George Shull's research of hybridization explains one of the key components of evolution, inheritance of gene variations.

At this site from The Nobel Foundation, read about the life and scientific discoveries of physicist Enrico Fermi (1901-1954), whose work with radiation and "discovery of nuclear reactions brought about by slow neutrons" earned him the...

A team of scientists studied the schooling behavior of threespine stickleback fish by experimentally testing how individual fish responded to an artificial fish school model.

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.
