Schematic representation of the known diversity of the Asgard archaea including the recently published lineages. In this schema, we indicate in orange and red the newly discovered lineages introduced in the two publications of Liu et al. ¹³ and Xie et al. ¹⁴ , respectively, and in grey new lineages not present in these publications corresponding to the Sifarchaea ¹² , the Jordarchaeia ¹⁶ and Asgard Lake Cootharaba ¹⁶ . The schema was designed combining the trees of all these publications. The suffix within brackets indicates that, depending on the authors, these lineages are considered to be Phylum (ota), Families (aceae), or Orders (ales). We locate the position of LAsCA (last Asgard archaeal common ancestor) based on the root observed in most phylogenetic trees, and used by Liu et al. to discuss the ESPs distribution. For each Asgard lineage, we also indicate the year of publication of the genome of its first representative, and changes in taxonomy are indicated by color changes of the dots. The light purple dots indicate that Asgards of the Karia and Hodar and lineages were described before 2017 as Loki 2 and Loki 3, respectively ¹ . In addition, the number of genomes available for each lineage is indicated within brackets.
