One of three optimal phylogenetic tree reconstructions with identical topologies recovered from an exhaustive maximum parsimony search (58 steps; CI = 1; RI = 1; HI = 0; RC = 1; = −0.707) of the abundance of viral replicon types of dsDNA, ssDNA, dsRNA, ssRNA(+), ssRNA(−), and retrotranscribing viruses. Abundance was scored on a 0–20 scale and ranged from 0 to 759 viral replicons. Vectors of abundance reconstructions in internal nodes are given as percentage of total abundance of replicons in superkingdoms. Boostrap support values are shown below nodes.
