Dating Alphaproteobacteria evolution with eukaryotic fossils - Nature Communications Dating early bacterial evolution is challenging due to the limited bacterial fossil record. Here Wang and Luo use the close evolutionary relationship between Alphaproteobacteria and mitochondria to le...

fantastic! even more fantastically, can consider these subs models in #molecularclock dating. see a blog article "Late better than never: time to consider complex subs models in inferring div time" sishuowang2022.wordpress.com/2026/03/17/l...

very happy to have this work published in mbe @molbioevol.bsky.social can now use phyloHessian to get a (hopefully) improved div time & subs rate estimate, particularly for deep-time or fast‑evolving lineages github.com/evolbeginner... #julialang #iqtree #mcmctree #molecularclock

Newick-formatted timetrees of the α-proteobacteria (Wang & Luo 2021) and bTOL (Wang & Luo 2025) are made available separately, such that no need to download the entire online datasets in case you r interested in only the timetree files. sishuowang2022.wordpress.com/resources/ #phylo #molecularclock

Studies in phylogeny and divergence times of Irpicaceae and Meripilaceae (Polyporales, Basidiomycota), with an emphasis on Ceriporia and Meripilus including ten new species Species in Ceriporia and Meripilus are important wood-decaying fungi causing white rot on both angiosperm and gymnosperm wood. Morphologically, the two genera share similar micromorphology: a monomiti...

Molecular clock analysis shows bacteria used oxygen long before widespread photosynthesis In a new study published in Science, researchers from the Model-Based Evolutionary Genomics Unit at the Okinawa Institute of Science and Technology (OIST) and their international collaborators have constructed a detailed timeline for bacterial evolution and oxygen adaptation. Their findings suggest some bacteria could use trace oxygen long before evolving the ability to produce it through photosynthesis.

Species diversity, taxonomy, multi-gene phylogeny, and divergence times of Meruliaceae (Polyporales, Basidiomycota) Meruliaceae is one of the three major families of the phlebioid clade in the Polyporales that consists primarily of wood-decaying species. We undertook an in-depth survey on species diversity, gene...
