#eukaryogenesis — Public Fediverse posts

Before the 'Oxygen Apocalypse', Earth was purple, the oceans ferrous, and H₂O's oxygen safely locked away 🟣

Then, bacteria developed a quantum lockpick 🗝️⚡

The seas rusted and the ancients died out. Complex organisms burn the fuel of this cataclysm still, but pay the price by ageing 🦠

This is the story of how symmetry saves us from the flames ⚛️

Evolutionary origins of the #lysosome-related #organelle sorting machinery reveal ancient homology in post-#endosome trafficking pathways: Kiran More et al. https://www.pnas.org/doi/10.1073/pnas.2403601121

"the BLOC machinery plays an important role in #microbes today for our ecosystem and health and may help to explain the #evolution of the basic cellular configuration over 1.5 billion years ago."
