Cyanobacteria are the only prokaryotes to have evolved oxygenic photosynthesis,
transforming the biology and chemistry of our planet. Genomic and evolutionary studies …

The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

Eukaryotic life appears to have flourished surprisingly late in the history of our planet. This
view is based on the low diversity of diagnostic eukaryotic fossils in marine sediments of mid …

In modern oceans, eukaryotic phytoplankton is dominated by lineages with red algal-derived
plastids such as diatoms, dinoflagellates, and coccolithophores. Despite the ecological …

The endosymbiotic origin of mitochondria during eukaryogenesis has long been viewed as
an adaptive response to the oxygenation of Earth's surface environment, presuming a …

Cyanobacteria played an important role in the evolution of Early Earth and the biosphere.
They are responsible for the oxygenation of the atmosphere and oceans since the Great …

Plant (archaeplastid) evolution has transformed the biosphere, but we are only now
beginning to learn how this took place through comparative genomics, phylogenetics, and …

The global biosphere is commonly assumed to have been less productive before the rise of
complex eukaryotic ecosystems than it is today. However, direct evidence for this assertion …

Few topics in geobiology have been as extensively debated as the role of Earth's
oxygenation in controlling when and why animals emerged and diversified. All currently …

Chlorophytes (representing a clade within the Viridiplantae and a sister group of the
Streptophyta) probably dominated marine export bioproductivity and played a key role in …
