With its beetling brows and jutting face, a gorilla could never pass for human, even at a fraternity party. Yet stripped to the bone, we primates are alike in many ways, such as in the position of the shoulder blades. To help students recognize the underlying similarities and differences among human beings, gorillas, and baboons, anthropologist John Kappelman of the University of Texas, Austin, created the e-Skeletons Project.

Users can study digital photos of the skull and other bones from multiple angles and highlight anatomical details. For example, color-coding pinpoints the different bones in the skull. Click to delineate muscle attachments, processes, tooth cusps, and other skeletal landmarks, or to see the points where one bone articulates with another. Another feature lets you juxtapose bones from different species. Kappelman plans to add chimpanzee and orangutan skeletons to the site.
