223 metagenomes reveal eukaryotes' deep origin outside Heimdallarchaeia within Asgardarchaeota, reshaping the evolutionary timeline dramatically! PMID:40335687, Nature 2025, @Nature https://doi.org/10.1038/s41586-025-08955-7 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Deep origin of eukaryotes outside Heimdallarchaeia within Asgardarchaeota | Nature
Research on the morphology, physiology and genomics of Asgard archaea has provided valuable insights into the evolutionary history of eukaryotes1–3. A previous study suggested that eukaryotes are nested within Heimdallarchaeia4, but their exact phylogenetic placement within Asgard archaea remains controversial4,5. This debate complicates understanding of the metabolic features and timescales of early eukaryotic ancestors. Here we generated 223 metagenome-assembled nearly complete genomes of Asgard archaea that have not previously been documented. We identify 16 new lineages at the genus level or higher, which substantially expands the known phylogenetic diversity of Asgard archaea. Through sophisticated phylogenomic analysis of this expanded genomic dataset involving several marker sets we infer that eukaryotes evolved before the diversification of all sampled Heimdallarchaeia, rather than branching with Hodarchaeales within the Heimdallarchaeia. This difference in the placement of euk

When Nature does a photo roundup, it’s always worth a scroll. March’s edition is packed with mind-blowing REAL shots that capture the beauty, weirdness, and wonder of science 🧪—no AI needed.

Case in point: this gorgeous shot of two courting crab spiders. Just one of many stunners. 💘

Happy Darwin Day!

To celebrate, the National University of Singapore released a collection of historical depictions of Darwin and of his and Wallace's theory of evolution by natural selection.

I like this portrait by Henry Furniss (1854 - 1925).
