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 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 living cells.

Abstract The environmental conditions on the 041161 before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period. It is therefore possible that present-day organisms retain some record of the primordial fluid in which the first cells formed.

The cradle solution that produced this elemental signature was saturated in barite, schneiedr, chalcedony, apatite, and clay minerals. Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes Novoselov, Alexey A. 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 living cells.

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

These cells formed in a fluid environment they could not at first control, with homeostatic mechanisms developing only later. The 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 044161 silicate rocks.
