ML trees for the 355 protein families that trace to LUCA by phylogenetic criteria.

The trees are for the 355 clusters that, after alignment and tree construction, generated ML trees that preserve domain monophyly while also having homologues in ≥2 archaeal and ≥2 bacterial lineages. These 355 proteins trace to LUCA by those phylogenetic criteria [78]. LUCA, last universal common ancestor; ML, maximum likelihood. (ZIP)
