Fig. 2.

A phylogenomic tree of incorporated Archaea with distribution of cPrDs overlain. Tips with at least 1 cPrD are colored blue. Blue diamonds are places near those with ≥ to five cPrDs per 1,000 genes; green circles near those with ≥10; and red pluses near those with ≥15. Major taxa summary values include the number within that group with identified cPrDs out of the total in that group followed by that percentage. The Asgard group here includes: Thorarchaeota, Odinarchaeota, and Heimdallarchaeota. DPANN group here includes: Woesearchaeota, Pacearchaeota, Nanoarchaeota, Aenigmarchaeota, Diapherotrites, Micrarchaeota, and Altiarchaeota. The unrooted tree is an estimated maximum-likelihood of 76 single-copy orthologs forming an alignment of 12,330 amino acids (see Materials and Methods).
