WebbRemember that phylogenetic trees depict degrees of relationship among taxa. On a phylogenetic tree, more closely related terminal taxa are connected by shallower nodes (i.e., nodes nearer to the tips of the tree) and more distantly related terminal taxa are connected by deeper nodes (i.e., nodes nearer to the base of the tree).
