WebThe sister group to DPANN comprises the Euryarchaeota and the TACK Archaea, including Lokiarchaeum, which our analyses suggest are monophyletic sister lineages. Metabolic reconstructions on the rooted tree suggest that early Archaea were anaerobes that may have had the ability to reduce CO 2 to acetate via the Wood–Ljungdahl pathway. WebArchaeal parent: archaeal lineage that was involved in the fusion event that gave rise to the origin of the eukaryotic cell. Archezoa: hypothetical eukaryotic clade that diverged prior to the origin of mitochondria. Clade: a monophyletic group of organisms. Eocyte: archaeal lineage from which certain eukaryotic features are thought to

WebSep 9, 2015 · 5. The archaeal ancestor of eukaryotes: a complex, ancient group within the TACK superphylum with a prototype phagocytic ability? Arguably, the greatest difficulty faced by the endosymbiotic scenarios of eukaryogenesis is the apparent implausibility (or at least extreme rarity) of the engulfment of one prokaryotic cell by another.
