4. Phylogenetic relationship among tetrapods, lobe-finned fishes and ray-finned fishes

B. ((tetrapods, ray-finned fishes), lobe-finned fishes) 0.40 0.39 ≤ 0.42 ≤ 0.81 0.11 0.07 0.51
  1. Hypotheses 1 A and B and hypotheses 2 A-D correspond to those shown in Figure 1A and 1B and Figure 2A,2B,2C,2D, respectively. Hypotheses supported in this study are shown in bold letters. Two types of bootstrap probabilities (intact and RELL, see Materials and Methods for their differences), P-values by the Kishino-Hasegawa (KH) test and the approximately unbiased (AU) test, the Bayesian posterior probability (BPP) and support values by the MRBAYES and TREE-PUZZLE programs are shown.
