The life cycle of an archaeon with multiple membranes
Many prokaryotes are diderms. They divide using an FtsZ division ring to simultaneously constrict physically coupled inner and outer membranes to form daughter cells with two membranes. Currently, onl...

Our paper is out in Nature Communications! 🌳🧬 We investigate the position of the archaeal root, the nature of the last archaeal common ancestor, and the evolution of DPANN archaea using state-of-the-art phylogenetic and gene-tree–species-tree reconciliation approaches. doi.org/10.1038/s414...

Phylogenetic reconciliation supports a methanogenic ancestor of the Archaea and a derived origin for host-associated lineages - Nature Communications
Key questions about the early evolution of archaea remain unanswered. Here, Huang et al. use improved methods of genome evolution to propose a euryarchaeal root for archaea, a methanogenic ancestor, a...

Our preprint on the 'Origins of Eukaryotic Metabolism' is out! Take a look at some of the new findings on the origin of eukaryotic membranes, metabolic integrations between archaeal and bacterial ancestors, and other fascinating prokaryotic interactions during eukaryogenesis. doi.org/10.64898/202...

Our analyses converge on a narrow archaeal root region at/near the base of the Euryarchaeota, supporting hypotheses in which the Last Archaeal Common Ancestor was a complex, free-living (hyper-)thermophilic methanogen.
