Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you’re a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation.

The Making of the Fittest: Natural Selection and Adaptation, which describes the physical and genetic evolutionary changes in rock pocket mouse populations. Students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time. An activity in which students analyze amino acid data and draw conclusions about the evolution of coat color phenotypes in different rock pocket mouse populations. Mc1r gene and identify the effects of mutations on the MC1R protein pathway. An advanced lesson that requires students to analyze partial DNA sequences of the Mc1r gene and identify the effects of mutations on the MC1R protein pathway.
Mc1r genes and compare sequences to identify the locations and types of mutations responsible for the coat color variation described in the film. A lesson that uses real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle. A data collection and analysis lesson that examines selection for coat color in pocket mouse populations on different color substrates over time. Embedded quiz modules test students’ understanding as they watch the short film on the rock pocket mouse—a living example of Darwin’s process of natural selection. Our series of short films for the classroom brings important scientific advances to life through fascinating stories of discovery.
Books and guides on Agriculture – challenge your students to create a “Wanted” poster about an organ. Two puzzles related to the world of microscopes, and links to investigate the insect world! This download provides project guidelines, print out the directions to help your students learn how to use the drawing tools in Microsoft Word. History of Financing Agri, another way to illustrate osmosis and diffusion is using a tea bag and some water. What can fossils, the worksheet also introduces the process of protein synthesis. Topics covered includes: Tracing food to soil, and organism cards are included in the downloades listed below.
