![]() ![]() Finally, students complete a VIDA chart (variation, inheritance, differential survival, adaptation) to EXPLAIN why elephants in Mozambique lost their tusks. The creator uses the evolution of the fur color of the rock pocket mouse as the phenomenon for this. It supports the short film, The Making of the Fittest: Natural Selection and Adaptation. Students answer questions as they watch the film to keep them on task. This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest. This lesson from HHMI BioInteractive is based on the classic study of the evolution of fur color in rock pocket mouse populations. 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. Each illustration shows the color variation at two different locations, A and B, at a particular moment in time. The first page of the lesson is a good time to have a discussion about what efforts humans should make to protect animals. The four illustrations provided by your teacher represent snapshots of rock pocket mouse populations. Information on this section of reading was summarized from The Great Elephant Census site. Record your answers to these questions on the separate answer sheet. The activity starts with a history lesson on the ivory trade and poaching. Warm-up The illustrations represent snapshots of rock pocket mouse populations at. The elephants studied at Gorongosa National Park show that females in a certain age group have a high frequency of tusklessness. The creator uses the evolution of the fur color of the rock pocket mouse as the phenomenon for this activity and uses it to address three of the four mechanisms that contribute to population adaptation through natural selection. Students had been studying evolution, looking at many HHMI resources like the Rock Pocket Mouse and Finches on the Galapagos. Students had been studying evolution, looking at many HHMI resources like the “ Rock Pocket Mouse” and Finches on the Galapagos. 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. Students review key concepts and mechanisms of evolution, including mutation, gene flow (or. You can find populations of rock pocket mice all over the Sonoran Desert in. students to analyze amino acid data and draw conclusions about the evolution of coat-color phenotypes in the rock pocket mouse. 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. Youll get a detailed solution from a subject matter expert that helps you.
