Overview
The discovery of the platypus had the scientific world in an uproar with its mammal-like and bird-like features. How was one to classify the platypus? This case study uses this issue to model the scientific process, with scientists arguing, debating, collecting more evidence, and revising their opinions as new data become available.
Chimpanzee Droppings Lead Scientists to Evolutionary Discovery

Resource type:
- Evo in the News article
Time: 20 minutes
Overview
This news brief from March of 2008 describes scientists' discovery of a new mammal species, a giant elephant shrew. Though elephant shrews resemble regular shrews, recent genetic evidence suggests that elephant shrews actually sprang from a much older (and perhaps more charismatic) branch of the tree of life - the one belonging to elephants and their relatives.

Resource type:
- Article
Time: 30 minutes
Overview
The popular press often describes scientific controversies regarding which species ancient hominin fossils represent and how they are related to one another. How should students interpret the frequent name changes experienced by our extinct relatives? What should they make of headlines that trumpet major revisions of the branching patterns on our limb of the tree of life? This article will help teachers develop instruction surrounding these issues, discourage misconceptions, and help students interpret media coverage in light of the process of science.
