We have shown that these lineages form a candidate superphylum, designated Asgard archaea, that affiliates robustly with eukaryotes in phylogenetic analyses, and that reconstructed Asgard genomes encode an enriched repertoire of eukaryotic signature proteins.

Previously, genetic studies have been used to group the seemingly disparate animals together in a superphylum called Ecdysozoa.

Average bootstrap support values are provided for each phylum and superphylum when resolved.
