Novel Predators Reshape Holozoan Phylogeny and Reveal the Presence of a Two-Component Signaling System in the Ancestor of Animals (Current Biology)

Hehenberger et al. describe three novel Holozoa and infer an updated phylogenomic framework for this group, in the course recovering a new lineage. Using comparative genomics, they show the presence of a two-component signaling system across all unicellular Holozoa and suggest the loss of this signaling system with the origin of animals.
