Finally, students complete a VIDA chart (variation, inheritance, differential survival, adaptation) to EXPLAIN why elephants in Mozambique lost their tusks. Rock Pocket Mouse (bee) evolution activity-3 - Name: Kailey Hernandez How Can Evolution Be Observed - Studocu Online lab work and the evolution of the rock pocket mouse. Students answer questions as they watch the film to keep them on task. Most rock pocket mice have a sandy, light-colored coat that enables them to blend in with the light color of the desert rocks and sand on which they live. I also put up a map of the world because many of my students need a geography reminder about where Africa is and how large it is.Īfter the discussion, students watch the HHMI film “Selection for Tuskless Elephants” which is about 7 minutes long. The rock pocket mouse, Chaetodipus intermedius, is a small, nocturnal animal found in the deserts of the southwestern United States. The first page of the lesson is a good time to have a discussion about what efforts humans should make to protect animals. Students look at cards showing light and dark mice on different substrates. It has been simplified from the original activity so that it is suitable for beginner biology students. ![]() Explain the presence of dark-colored mice at location A. This worksheet was modified from the HHMI Activity on color variation in the rock pocket mouse. This worksheet was modified from the HHMI Activity on color variation in the rock pocket mouse. Student explanations should include coat color as an important means of camouflage for the rock pocket mice. Remember that fitness is defined by an organism’s ability to survive and produce offspring. Information on this section of reading was summarized from The Great Elephant Census site. Explain why a rock pocket mouse’s color influences its overall fitness. The activity starts with a history lesson on the ivory trade and poaching. The elephants studied at Gorongosa National Park show that females in a certain age group have a high frequency of tusklessness. Students had been studying evolution, looking at many HHMI resources like the “ Rock Pocket Mouse” and Finches on the Galapagos. The fittest individuals are the ones that are most successful at reproducing.This activity was created for an evolution unit in an intro biology class (1 semester class) where I wanted to include a little bit of ecology and conservation science. Alternatively, the illustrations can be projected to the whole class or uploaded for students to view online. ![]() ![]() Print and cut the illustrations into cards for each group of students, making sure to keep the number (1, 2, 3, 4) at the top of each illustration. It covers the principles/concepts of natural selection: population, variation, overproduction of offspring, adaptation, fitness, and selective pressure. Download the Rock Pocket Mouse Illustrations file from the activity webpage.

This ten minute film shows adaptive changes in rock pocket mouse populations, demonstrating the process of natural selection and can be accessed at. “Survival of the fittest means the strongest survive fitness means physical fitness.” In reality, fitness in this case is reproductive fitness. Here is a PowerPoint I made on evolution by natural selection. ![]()
