Teaching Students About the Supraorbital Torus

The supraorbital torus is a bony ridge located above the eye sockets in some primates, including humans. This feature has been the subject of research and discussion in the fields of anthropology and evolutionary biology. However, it can also be a fascinating topic to teach to K-12 students. Here are some activities to introduce the supraorbital torus to students at different grade levels.

Primary school:

For young students, a fun way to introduce the supraorbital torus is to use pictures. Print out or project images of different animals whose skulls have visible supraorbital tori. Ask students to identify the feature and describe its location and appearance. You can also use this activity to teach students about different animal species and their habitats.

Middle school:

Middle school students can learn more about the evolutionary significance of the supraorbital torus. Begin by reviewing the basic concepts of evolution and natural selection. Then, show examples of hominid skulls from different periods and ask students to identify whether they have supraorbital tori or not. Discuss how this feature might have provided an advantage in early hominid populations, such as protection against impacts or strengthening the skull for chewing tough foods.

High school:

For high school students, delve deeper into the biomechanics and function of the supraorbital torus. Introduce theory and evidence regarding the evolution of the human skull and the relationship between cranial structures and behavior. Use examples from modern human populations to highlight how variation in supraorbital torus morphology might relate to differences in diet and physical activity. Finally, challenge students to design an experiment or study to test hypotheses related to the supraorbital torus and its influence on one or more aspects of human biology.

Regardless of grade level, teaching students about the supraorbital torus can help them understand the complexity and diversity of biological and cultural evolution. By using engaging and developmentally appropriate activities, K-12 teachers can make this topic both enjoyable and informative for their students.
