archaeaeukaryotes
The term archaeaeukaryotes refers to the proposed clade that groups archaea and eukaryotes as closely related lineages within a common evolutionary framework. In some literature it is used to describe the conceptual unity of Archaea and Eukarya, highlighting their genetic affinities.
In traditional taxonomy life has been divided into three domains: Bacteria, Archaea, and Eukarya. In a two-domain
Support comes from comparative genomics and the discovery of Asgard archaea (Lokiarchaeota, etc.) which possess numerous
Eukaryogenesis is believed to involve an archaeal host acquiring endosymbiotic bacteria that became mitochondria, followed by
Consequently, archaeaeukaryotes would exhibit a mosaic genome combining archaeal transcription and replication machinery with eukaryotic-like cellular
The concept remains debated, and ongoing genomic and phylogenetic studies refine the boundaries and composition of
