Cladograms Cladograms are diagrams that show the relationship among organisms based on traits. Example: # of shared characteristics
Phylogeny They show the evolutionary history. Cladograms are like family trees. Those that are closer and share more traits are more closely related. The base of each branch represents a common ancestor.
