New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga). 🔗 DOI: www.biorxiv.org/content/10.6...

Save the date! The next instalment of Comparative Genomics of Unicellular Eukaryotes is a GO! Join us next year for a programme of talks, posters, ECR/networking activities. Website and registration details to follow in the coming weeks. See you October 5-10 2026 in beautiful San Feliu!!
