The innovation of the eukaryotic cell revolutionised the biosphere & transformed the planet, but the drivers behind this process remain debated. New paper out @natureportfolio.nature.com co-led by @fossils.bsky.social w/ Susannah Porter, Galen Halverson & Maggie Whelan @mcgillscience.bsky.social 🌎

Excited to say that my new paper with @maxlechte.bsky.social (and others not on bluesky) has come out in @nature.com! Study of sediments, geochemistry and fossils from rocks 1.75 to 1.4 billion years old indicate that the oldest known #eukaryotes were aerobic and benthic! #protists rdcu.be/fjNgL

Was great to chat to @evolutionsoup.bsky.social about the climate change in the Neoproterozoic and how it might have affected the biosphere. Thanks for having me! ⚒️

Newly landed in Bluesky! I'm Max, a postdoc in geobiology at @sydney.edu.au (previously Melbourne, McGill). I use the sedimentary record to better understand ancient environmental change, the evolution of early eukaryotes, and the strange world they emerged in. Here's me with some 2.3 Ga glacials
