Eukaryogenesis and oxygen in Earth history
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 …

Evolution of Atmospheric O2 Through the Phanerozoic, Revisited
An oxygen-rich atmosphere is essential for complex animals. The early Earth had an anoxic
atmosphere, and understanding the rise and maintenance of high O2 levels is critical for …

Extreme variability in atmospheric oxygen levels in the late Precambrian
Mapping the history of atmospheric O2 during the late Precambrian is vital for evaluating
potential links to animal evolution. Ancient O2 levels are often inferred from geochemical …

Reconstructing Earth's atmospheric oxygenation history using machine learning
Reconstructing historical atmospheric oxygen (O2) levels at finer temporal resolution is a top
priority for exploring the evolution of life on Earth. This goal, however, is challenged by gaps …

Continental configuration controls ocean oxygenation during the Phanerozoic
The early evolutionary and much of the extinction history of marine animals is thought to be
driven by changes in dissolved oxygen concentrations ([O2]) in the ocean,–. In turn,[O2] is …
