Figure 1: A phylogenetic tree with the characteristic flavors mapped onto it.
Two technical notes:
1. I have marked all characters with their earliest hypothesized evolution date.
2. Organisms with boxes at the tree tips were used as data input into the model; branch tips without terminal boxes were assigned a flavor (their branch or group was assigned the flavor) inferred by the program based on shared ancestry (MacClade, ver 3.06; Maddison and Maddison 1992).
