The nature of the last universal common ancestor and its impact on the early Earth system: https://www.nature.com/articles/s41559-024-02461-1 -> New findings raise questions about when (and where) life began: https://bigthink.com/hard-science/new-findings-raise-questions-about-when-and-where-life-began/ - a recent study pushes back the estimated age of the Last Universal Common Ancestor #LUCA to around 4.2 billion years ago, several hundred million years older than previous estimates.
NatureThe nature of the last universal common ancestor and its impact on the early Earth system - Nature Ecology & EvolutionIntegration of phylogenetics, comparative genomics and palaeobiological approaches suggests that the last universal common ancestor lived about 4.2 billion years ago and was a complex prokaryote-grade anaerobic acetogen that was part of an ecosystem.
