... phylogenetic tree diagrams. To this end, I provide clarifications of terminology and address the problematical status of “ancestors.” Cladograms are not genealogies viewed from a distance, but empirical hypotheses of relationship based on the distribution of shared derived character states. I describe an...

Although it is designed using mammalian cranial characters, the activity could be adapted for characters from any group of organisms.
