P value of SH test versus length of simulated datasets. SH tests were done between ML best trees and derived trees with a collapsed node for the original dataset (8174 bp) and three simulated datasets (10 kb, 12 kb, and 14 kb). The simulated datasets were obtained with the same nucleotide frequency and substitution parameters found in the original dataset. Nodes A, B, C, D, and E are labeled in Figure 2.
