The Neoproterozoic (1000-542 million years ago, Mya) was characterized by profound global environmental and evolutionary changes, not least of which included a major rise in atmospheric oxygen concentrations [1, 2], extreme climatic fluctuations and global-scale glaciation [3], and the emergence of metazoan life in the oceans [4, 5]. We present here phylogenomic (135 proteins and two ribosomal RNAs, SSU and LSU) and relaxed molecular clock (SSU, LSU, and rpoC1) analyses that identify this… Expand
Nitrogen-Fixing Heterocystous Cyanobacteria in the Tonian Period
TLDR
Tonian filamentous cyanobacteria are reported that are characterized by large cells, binary fission (for filament elongation), hormogonia (for asexual reproduction and dispersal), probable akinetes (for survival in adverse conditions), and by implication, diazotrophic heterocysts. Expand
Could cyanobacteria have made the salinity transition during the late Archean?
TLDR
This study supports the hypothesis of Cyanobacterial evolution in freshwater environments and their transition into increasingly salty environments during the late Archaean, prior to the GOE. Expand
Crown group Oxyphotobacteria postdate the rise of oxygen
TLDR
Cross-calibrated Bayesian relaxed molecular clock analyses show that crown group Oxyphotobacteria evolved ca. Expand
Coupling of ocean redox and animal evolution during the Ediacaran-Cambrian transition
TLDR
A comprehensive N-isotope dataset from the Yangtze Basin is presented that reveals remarkable coupling between δ15N, δ13C, and evolutionary events from circa 551 to 515 Ma, and shows that increased nutrient nitrogen availability may have exerted an important control on both macroevolution and ocean oxygenation. Expand
Cyanobacteria and the Great Oxidation Event: evidence from genes and fossils
TLDR
Relaxed clock analyses provide firm support for an origin of cyanobacteria in the Archean and a transition to multicellularity before the GOE, and it is likely that multice cellularity had a greater impact on cyanobacterial fitness and thus abundance, than previously assumed. Expand
Proterozoic Photosynthesis – a critical review
TLDR
The fossil record offers a unique view of photosynthesis in deep time, but is deeply compromised by differential preservation and non-diagnostic morphologies, and undermines the results of various ancestral state reconstruction analyses, as well as molecular clock estimates calibrated against demonstrably problematic Proterozoic fossils.

TLDR
The hypothesis that the first appearance of large, multicellular heterotrophs was fueled by an elevated supply of nutrients and carbon from the bottom of the food chain to higher trophic levels is explored, fueling an arms race toward larger grazers, predators and prey and the development of increasingly complex feeding and defense strategies. Expand
Comparative genomics reveals surprising divergence of two closely related strains of uncultivated UCYN-A cyanobacteria
TLDR
The results suggest that UCYN-A1 and UCyn-A2 had a common ancestor and diverged after genome reduction, suggesting that these two variants may reflect adaptation of the host to different niches, which could be coastal and open ocean habitats. Expand
Life: the first two billion years
TLDR
It is indicated that the first bacteria were shaped by anoxic environments, with distinct patterns of major and micronutrient availability, and the microbial underpinnings of modern marine ecosystems began to take shape halfway through Earth history. Expand
Radiation of nitrogen-metabolizing enzymes across the tree of life tracks environmental transitions in Earth history
TLDR
These findings provide novel constraints for understanding the evolution of the nitrogen cycle over time and provide insights into the bioavailability of various nitrogen sources in the early Earth with possible implications for the emergence of eukaryotic life. Expand

Proterozoic ocean redox and biogeochemical stasis
TLDR
This model suggests that the oceanic Mo reservoir is extremely sensitive to perturbations in the extent of sulfidic seafloor and that the record of Mo and chromium enrichments through time is consistent with the possibility of a Mo–N colimited marine biosphere during many periods of Earth’s history.

The evolutionary diversification of cyanobacteria: molecular-phylogenetic and paleontological perspectives.
TLDR
It is suggested that the clade of cyanobacteria marked by cell differentiation diverged once between 2,450 and 2,100 Ma, providing an internal bacterial calibration point for studies of molecular evolution in early organisms. Expand
Ocean oxygenation in the wake of the Marinoan glaciation
TLDR
The data provide evidence for an early Ediacaran oxygenation event, which pre-dates the previous estimates for post-Marinoan oxygenation by more than 50 million years, and seem to support a link between the most severe glaciations in Earth’s history, the oxygenation of the Earth's surface environments, and the earliest diversification of animals.

Reassessing the first appearance of eukaryotes and cyanobacteria
TLDR
The results eliminate the evidence for oxygenic photosynthesis ∼2.7 Gyr ago and exclude previous biomarker evidence for a long delay between the appearance of oxygen-producing cyanobacteria and the rise in atmospheric oxygen 2.45–2.32 billion years ago. Expand
