This site from Palomar college explains what gene flow is and describes a situation where this occurs in humans. Information is brief but factual.

This site from the University of Connecticut is Kent Holsinger's site on The Hardy-Weinberg Principle. A great site to check out on the subject, with links to additional information, including: derivation of the Hardy-Weinberg Principle,...

Take this interactive, multiple-choice quiz over evolution, then review your score and any missed questions at the end.

This resource provides directions for a lab in which students observe changes in a gene pool of bunnies affected by natural selection. Includes PDF resources.

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.

Students discover that variation in plants allows some varieties to survive in near-drought conditions. Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection...

Discusses how unique species evolve when geographic barriers restrict population interbreeding, such as when organisms are confined to an island. Examples are provided.

An explanation of the process of gene flow and how it can cause genetic variation within a population.

Take this post test to see how much you know about genome evolution.

Although pesticides are designed to kill pest populations, they are seldom 100% effective -- a few individuals usually survive and reproduce. These survivors may have a behavioral trait that helps them avoid the pesticide, a biochemical...

Explains what stabilizing selection is and how this type of natural selection actually limits genetic diversity in a population. Presents examples of stabilizing selection in different plants and animals.
