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 …

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 …

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 …

Earth's surface has undergone a protracted oxygenation, which is commonly assumed to
have profoundly affected the biosphere. However, basic aspects of this history are still …

The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

The extent to which Paleozoic oceans differed from Neoproterozoic oceans and the causal
relationship between biological evolution and changing environmental conditions are …

Atmospheric oxygen is thought to have played a vital role in the evolution of large, complex
multicellular organisms. Challenging the prevailing theory, we show that the transition from …

Life on Earth has existed for over 3.5 billion years and has caused fundamental changes in
Earth's biogeochemistry. However, the timing and impact of major events in the evolution of …

Understanding causal relationships between evolution and ocean oxygenation hinges on
reliable reconstructions of marine oxygen levels, typically from redox-sensitive geochemical …

Among the most important innovations in the history of life is the transition from single-celled
organisms to more complex, multicellular organisms. Multicellularity has evolved repeatedly …
