Phylogenetic placement of the urancestor in trees of proteomes reconstructed from FSF domain structure. A single most parsimonious tree of proteomes that included the urancestral min_set (1,388 parsimoniously informative sites; 132,829 steps; CI = 0.080; RI = 0.773; g1 = -0.3354) or the max_set (1,388 parsimoniously informative sites; 134,801 steps; CI = 0.090; RI = 0.773; g1 = -0.239) as artificial taxa was recovered from a maximum parsimony analysis of genomic abundance levels of 1,420 FSFs (characters) in 421 proteome (taxa). Cladograms and subtrees containing the urancestor and a set of 10 taxa that were the most basal in the trees show that urancestral sets are more ancient than any of the 420 FL proteomes that were analyzed. Phylogenetic relationships with BS > 50% are displayed above branches.
