From: The prevalence of terraced treescapes in analyses of phylogenetic data sets
Origin of terraces. The two-locus taxon coverage pattern (displayed as a taxon coverage matrix, left) of a data alignment induces two subtrees, T|Y1 and T|Y2, of a tree, T, inferred from the data. Three trees, T, T’, and T” all display and are parent trees of T|Y1 and T|Y2. If the tree scoring function is parsimony or ML-EUL, the scores of T, T’, and T” are identical, and the trees constitute a terrace. Figure adapted from [27]. Credit: J. Charboneau
