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.

In this project, we investigated the root of Archaea using a range of phylogenetic approaches, including the best available site- and branch-heterogeneous substitution models, and new gene tree-species tree reconciliation models. doi.org/10.1093/bioi...

There's a PhD position now available with me in Bath, on the evolution of symbiosis. www.findaphd.com/phds/project.... The supervisory team also includes @anja1.bsky.social @phil-donoghue.bsky.social and others. NB, this is open both to UK-based students *and* to international students :)

Huang, @tweethinking.bsky.social, Sepang et al. use phylogenetic analyses to reveal that the Njordarchaeales and Panguiarchaeales constitute the new class Njordarchaeia within Asgard archaea. 🔗 doi.org/10.1093/molbev/msaf201 #evobio #molbio #archaea

I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.

New preprint up now! Interested in the evolution of halophily within DPANN archaea we decided to investigate the sister phylum to the Nanohaloarchaeota, GTDB phylum EX4484-52, for which we propose the name Caliditerrarchaeota www.biorxiv.org/content/10.1...

#Asgard,#phylogeny 1/ 🧵 Does MAGs contamination affect the placement of Njord as suggested by Zhang et al, 2025? www.nature.com/articles/s41... Our updated analysis suggests instead... www.biorxiv.org/content/10.1...

Microbial people! Especially postdocs and maybe some assistant professors who are feeling antsy ... the University of Montana is doing a search for a microbiologist! This is a great department, in a great place. (I worked there for 10 years, loved it, ping me with Qs) apply.interfolio.com/159494
