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 …

Abstract The 'Cambrian Explosion'describes the rapid increase in animal diversity and
abundance, as manifest in the fossil record, between~ 540 and 520 million years ago (Ma) …

The macronutrient phosphorus is thought to limit primary productivity in the oceans on
geological timescales. Although there has been a sustained effort to reconstruct the …

Phosphorus is a limiting nutrient that is thought to control oceanic oxygen levels to a large
extent,–. A possible increase in marine phosphorus concentrations during the Ediacaran …

Sedimentary rocks deposited across the Proterozoic–Phanerozoic transition record extreme
climate fluctuations, a potential rise in atmospheric oxygen or re-organization of the seafloor …

Nitrogen is an essential nutrient for all life on Earth and it acts as a major control on
biological productivity in the modern ocean. Accurate reconstructions of the evolution of life …

The rapid increase of carbon dioxide concentration in Earth's modern atmosphere is a
matter of major concern. But for the atmosphere of roughly two-and-half billion years ago …

Atmospheric reactions and slow geological processes controlled Earth's earliest nitrogen
cycle, and by~ 2.7 billion years ago, a linked suite of microbial processes evolved to form the …

Major insights into the phylogenetic distribution, biochemistry, and evolutionary significance
of organelles involved in ATP synthesis (energy metabolism) in eukaryotes that thrive in …

The ocean‐atmosphere system is typically envisioned to have gone through a unidirectional
oxygenation with significant oxygen increases in the earliest (ca. 635 Ma), middle (ca. 580 …
