Eukaryotic life appears to have flourished surprisingly late in the history of Earth. This view is based on the low diversity of diagnostic eukaryotic fossils in marine sediments of mid-Proterozoic age (around 1.6 billion to 800 million years ago) and an absence of steranes, the molecular fossils of eukaryotic membrane sterols. This scarcity of eukaryotic remains is difficult to reconcile with molecular clocks that suggest that LECA had already emerged between around 1.2 and more than 1.8 billion years ago. LECA, in turn, must have been preceded by stem-group eukaryotic forms by several hundred million years. Brocks et al. report the discovery of abundant protosteroids in sedimentary rocks of mid-Proterozoic age. Image credit: Arek Socha.
