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...

Finally, here is a genetics worksheet that does not include Punnett squares! Designed for a more advanced class, biology learners will compare Lamarck's concept of evolution with Darwin's. They will explore the Hardy-Weinberg equilibrium...

Thirty short-answer questions comprise this detailed review of evolution theory. Many of the questions ask scholars to define vocabulary. Because short answers are required, this worksheet will take some time to complete. You could give...

How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and...

In this evolution worksheet, students will answer questions about population genetics and the theory of evolution of species. This worksheet has 15 true or false, 6 fill in the blank, and 4 short answer questions.

In this theory of evolution worksheet, students review vocabulary words associated with evolution including the different types of evolution patters. This worksheet has 5 true or false and 5 matching questions.

In this evolution learning exercise, students will complete a table by writing in the era and biological event based on 4 different time periods of Earth's history. Students will answer 8 fill in the blank questions based on the...

This explanation of genetic drift is straightforward and easy to understand. Illustrations are provided to help visual learners

Explains what genetic drift, gene flow, and natural selection are, and compares their differences, two at a time.

Laurence Moran discusses one of the most important mechanisms of evolution, Random Genetic Drift.

This is a college level lecture on genetic drift, complete with mathmatic formulae, includes special links.

Find out how evolution happens due to chance events. Explore the bottleneck effect and founder effect.

Gene pools can change as a result of genetic drift and other mechanisms. This tutorial will investigate how gene pools change and evolve.

This is a group of Mendelian Genetics exercises that are designed to show the evolution of a trait within a population. The site covers instruction in calculating genotypic and allelic frequencies, determining dominance, the...

An interview with Douglas Futuyma, renowned evolutionary scientist, explaining the theory of natural selection and how it steers toward evolution.

Discover what evolution is through a case study of a Hawaiian snail species' survival. [7:20]

[Free Registration/Login may be required to access all resource tools.] Students will explore the factors that lead to evolution such as genetic mutation, gene drift and gene flow.

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.

Viral genomes are the fastest evolving entities in biology, mainly because of their short replication time and the large quantity of offspring released per cell infected. Evolution occurs by several mechanisms: Random mutation,...

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...

[Free Registration/Login may be required to access all resource tools.] Describes three of the four forces of evolution: mutation, gene flow, and genetic drift.

Scientific article explaining what natural selection is, and how it manifests itself through genetics and from generation to generation. Natural selection is compared to genetic drift, both of which cause evolution to occur. The limits...

Examine the six major mechanisms of evolution and evolutionary processes.

Teach aliens about evolution as you play this game, and review your own understanding in the process. Topics covered include evolutionary mechanisms, evidence of evolution, natural selection, reproductive isolation, population genetics,...
