Comment on this resource
This lesson uses a series of nested plastic bags as a 3-dimensional Venn diagram to illustrate the hierarchical grouping of organisms based on their shared derived characters, thus forming the basis of a cladogram. Students will learn that the groups-within-groups hierarchical pattern of Linnaean classification is a result of both extinction and branching from common descent.
