Microevolution Teacher Resources

If some genes were exposed to microwaves, would that cause microevolution? In the video, scholars learn about microevolution or any change in the allele frequency of a population. The instructor explains the five ways microevolution...

AP biology buffs define vocabulary terms and answer critical-thinking questions about evolutionary trends. They compare macroevolution to microevolution, differentiate ploidy possibilities, explain isolation barriers, and more....

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...

Students describe the anatomy of a virus. In this biology lesson, students compare and contrast the characteristics of bacteria and viruses. They discover the genetic adaptations of viruses over time.

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...

Students examine natural selection, how it works and how it can cause microevolution.  In this evolution lesson students complete a lab activity that shows the effects that natural selection has on organisms.

About 70 percent of the genes of the stickleback fish are the same as humans. In the video, scholars further explore the stickleback fish and its history, from being removed from Loberg Lake to their change and comeback. Over time, these...

Population genetics deals with genetic differences within and between populations. The video explains why this is the lowest level of evolution. Then it discusses mutations, environmental factors, genetic recombination, and random gamete...

Although the instructions include reading from a specific textbook, the tasks are appropriate for any unit dealing with how genotype frequency changes over time. Junior biologists define five vocabulary terms and then answer five...

[Free Registration/Login may be required to access all resource tools.] Does evolution only happen gradually through small changes? Or is it possible that drastic environmental changes can cause new species to evolve? Or can both small...

Understand the difference between microevolution and macroevolution.

Get an overview of the process of microevolution.

The concepts of microevolution and macroevolution are explained and a two-column table that compares them is presented.

Paul Andersen defines microevolution as any change in the frequency of the allele pool. He then explains the five mechanisms of evolution; small sample size, non-random mating, mutations, gene flow and natural selection.

A general overview over the evolution of one population or one species over a short period of time.

What is evolution? This thorough site provides the basics of evolution focusing on the history of life, processes of evolution, microevolution, macroevolution, and more.

Paul Andersen describes microevolution and macroevolution in the stickleback fish of Loberg Lake. He describes how anadramous fish repopulated the lake after poisoning and adapted to the new environment through natural selection. He also...

[Free Registration/Login may be required to access all resource tools.] Introduction to macroevolution, microevolution, and population genetics.

Macroevolution and microevolution are defined, along with mutation, migration, genetic drift, and natural selection, which are "established mechanisms of evolutionary change."

Video discusses the concept of evolution and the five processes that can cause it to happen. [5:24] Includes a brief quiz and a list of additional resources to explore.

A description of the process of evolution explaining the Hardy-Weinberg Principle and the mechanisms that cause it. Also the website contains links for lessons on simulation of the natural selection process in the classroom and how the...

This unit plan presented by the Evolution and the Nature of Science Institutes is one way to introduce evolution. The authors have created a Pre-test about what evolution is/is not to address misconceptions. There are handouts and...

Through fossils scientists have been able to study the evolution of whales. Read this article to take a closer look at the details.

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