Take a closer look into the modern view of evolution. This article includes many pieces of evidence, all which support the theory of evolution.

Today, about one-tenth of the world's population are southpaws. Why are such a small proportion of people left-handed -- and why does the trait exist in the first place? The following video investigates how the uneven ratio of lefties...

Explain how the isolated and homegeneous population of Iceland makes research in family ancestry simpler than in other cultures. Investigate the work of genealogists, and trace your own heritage as far as you can without extensive research.

This site from Palomar College describes the conditions needed for theHardy-Weinberg Principle to hold true.Completes sample calculations involvingthis principle.

Learners explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents...

Discusses the historical background leadingto the development of the Hardy-Weinberg principleand the assumptions of the principle. Providesmathematical and graphical illustrations ofthis principle.

Explains what meiosis is and what happens during crossing over where genetic material is exchanged between chromosomes. This process is important for ensuring that there is lots of genetic variation in a population as it improves survival.

A collection of video lectures introducing beginning biology students to the principles of evolution, ecology, and behavior. The course was taught three times a week for a semester at Yale University. The course discusses concepts of...

Learn how to find allele frequency and how it's different from genotype frequency.

[Free Registration/Login may be required to access all resource tools.] Natural selection acts on the phenotype (traits or characteristics) of an individual. On the other hand, natural selection does not act on the underlying genotype...

Written for younger students, this site explains biodiversity and links to easy to understand explanations of species and genetic diversity.

Describes the four broad categories of human races in the world, their geographical origins, and their sub-types. Also discusses the difficulties of tracing all branches of a race throughout human history, which is even more so today...

This site explores what Hardy-Weinberg Equilibrium is, and how teachers can explore this topic in their classrooms. Content includes background information on this topic, as well as numerous learning activities.

Based off of the hit television show NUMB3RS, this lesson shows students the scientific reasoning behind the societal taboo of incest. Students complete a Punnett square to determine the chances of an offspring inheriting two recessive...

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.
