FIGURE 3. Likelihood mapping results for three hypothetical data sets. Each corner of the triangle represents a different phylogenetic hypothesis for the arrangement of four taxa. Figures represent the percentage of dots in each part of the triangle, where dots represent quartets of sequences sampled from an alignment of DNA sequences. In (a) most points cluster in all three corners; in the general approach to likelihood mapping this would represent a dataset with strong phylogenetic signal, in the context of testing a specific hypothesis it would represent a data set in which the results depend on which taxa are sampled from each group. In (b) most points cluster in the middle; in either approach this would represent a data set with little or no phylogenetic signal. In (c) most points cluster in one corner (lower left); this would represent a strong and consistent phylogenetic signal in favour of one particular hypothesis.
