A new study highlights how life possibly evolved prior to and during the rise of Earth’s oxygenated atmosphere.

To identify when oxygen levels rose enough to oxygenate the deep ocean, experts undertook an expedition, according to Earth.com. They examined the oxidation state of iron in igneous rocks formed ...

highlighting the role of different oxidation pathways depending on the energy of the oxygen molecules involved. The research demonstrated that both thermal and high-energy molecular beam exposures ...

The paper states that microbes’ lifestyles in their respective ... likely more important as oxygen levels increased throughout the Great Oxidation Event. In his three decades at MSU, Inskeep has ...
