The setting for this case study is a paleontological dig in East Africa, where an undergraduate student has unearthed part of what appears to be an ancestral human skull. Students read the story and then examine a number of primate skulls. They are asked to build a phylogeny based on their observations.
- [History of life: Grades 13-16] Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- [Evidence of evolution: Grades 13-16] An organism's features reflect its evolutionary history.
- [Evidence of evolution: Grades 13-16] There is a fit between the form of a trait and its function, though not always a perfect fit.
- [Evidence of evolution: Grades 13-16] The fossil record provides evidence for evolution.

The case study includes teaching notes. It was originally designed for a lower division laboratory course that accompanies a lecture course in physical (biological) anthropology. Also, note that the lesson is titled "The missing link." This phrase can reinforce misconceptions. For clarification, see our page on common teaching pitfalls.
