Happy to share Jialin's first publication. She did a great job exploring the transition to land in animals. Co-supervised by the great Jordi Paps and me and in collaboration with Davide Pisani and @phil-donoghue.bsky.social
Nature research paper: Convergent genome evolution shaped the emergence of terrestrial animals

Convergent genome evolution shaped the emergence of terrestrial animals - Nature
Comparisons of 154 genomes from 21 animal phyla and outgroups have been used to reconstruct ancestral adaptation to life on land across 11 distinct terrestrialization events, revealing strong evidence for convergent genomic evolution across the animal kingdom and recurring periods of terrestrial colonization.

Really pleased to be part of this project which shows that aerobic bacteria arose in the Archaean, long before the GOE - after which aerobes proliferated through HGT. Fun @bristolpalaeo.bsky.social collab including @tweethinking.bsky.social @sabifo4.bsky.social @emoody.bsky.social Davide Pisani
Dating Bacteria is hard due to the lack of maxima. Assuming aerobes likely postdated the GOE gave us better resolved ages, but also surprised us, but not Dr Dayhoff, showing O2 use predated its atmospheric rise by 900 Mys and helped oxygenic photosynthesis to evolve. www.science.org/doi/10.1126/...
