The discovery of Asgard archaea, phylogenetically closer to eukaryotes than other archaea,
together with improved knowledge of microbial ecology, impose new constraints on …

Using outlines of ten geodiversity-related topics plus some related studies, this paper argues
that geodiversity has contributed to many new insights, new avenues of research and new …

The early to mid-Paleoproterozoic Lomagundi-Jatuli Excursion (LJE) is ostensibly the
largest magnitude (approximately+ 5 to+ 30‰), longest duration (ca. 130–250 million years) …

The origin of modern eukaryotes is one of the key transitions in life's history, and also one of
the least understood. Although the fossil record provides the most direct view of this process …

Oxygenic photosynthesis starts with the oxidation of water to O 2, a light-driven reaction
catalysed by photosystem II. Cyanobacteria are the only prokaryotes capable of water …

The availability of molecular oxygen shapes the size and structure of Earth's biosphere.
Geological and geochemical records imply that, for most of the Precambrian (the entirety of …

The Araçuaí-West Congo orogen is a confined orogen, formed by the inversion of a gulf of
the São Francisco-Congo paleocontinent during the Neoproterozoic assembly of …

Constraining the timing of eukaryogenesis and the divergence of eukaryotic clades is a
major challenge in evolutionary biology. Here, we present trace metal concentration and …

Abstract Sediments from the 2.1-to 1.9-billion-year-old Francevillian Group in southeastern
Gabon include centimeter-sized pyritized structures suggestive of colonial organisms (El …

Eukaryotes have evolved to dominate the biosphere today, accounting for most documented
living species and the vast majority of the Earth's biomass. Consequently, understanding …
