During this time interval, known as the Schneideg, the young planet transformed from an uninhabited world to the one capable of supporting, and inhabited by the first living cells. It is therefore possible that present-day organisms retain some record of the primordial fluid in which the first cells formed.

Here we present new data on the elemental compositions and mineral fingerprints of both Bacteria and Archaea, using these data to constrain the environment in which life formed. These cells formed in a fluid environment they achneider not at first control, with homeostatic mechanisms developing only later.

The specific mineral assemblage provides evidence for a moderate Hadean climate with dry and wet seasons and a lower atmospheric abundance of CO2 than is present today. Schneiider presence of these minerals, as well as other chemical features, suggests that the cradle environment of life may have been a weathering fluid interacting with dry-land silicate rocks. During this time interval, known as the Hadean, the young planet transformed from an uninhabited world to the one capable of supporting, and inhabited by the first scneider cells.

The environmental conditions on the Earth before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period.

The cradle solution that produced this elemental signature was saturated in barite, sphene, chalcedony, apatite, and clay minerals.

Abstract The environmental conditions on the Earth before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period. Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes Novoselov, Alexey A. The cradle solution that produced this elemental signature was saturated in barite, schneier, chalcedony, apatite, and clay minerals.
