[HTML][HTML] Was hydrogen peroxide present before the arrival of oxygenic photosynthesis? The important role of iron (II) in the Archean ocean
WH Koppenol, H Sies - Redox Biology, 2024 - Elsevier
We address the chemical/biological history of H 2 O 2 back at the times of the Archean eon
(2.5–3.9 billion years ago (Gya)). During the Archean eon the pO 2 was million-fold lower …

An abiotic source of Archean hydrogen peroxide and oxygen that pre-dates oxygenic photosynthesis
The evolution of oxygenic photosynthesis is a pivotal event in Earth's history because the O2
released fundamentally changed the planet's redox state and facilitated the emergence of …

The energy expansions of evolution
OP Judson - Nature ecology & evolution, 2017 - nature.com
The history of the life–Earth system can be divided into five 'energetic'epochs, each featuring
the evolution of life forms that can exploit a new source of energy. These sources are …

Plausible sources of membrane-forming fatty acids on the early Earth: a review of the literature and an estimation of amounts
The first cells were plausibly bounded by membranes assembled from fatty acids with at
least 8 carbons. Although the presence of fatty acids on the early Earth is widely assumed …

Photoferrotrophy: remains of an ancient photosynthesis in modern environments
Photoferrotrophy, the process by which inorganic carbon is fixed into organic matter using
light as an energy source and reduced iron [Fe (II)] as an electron donor, has been proposed …
