The 'Water Problem'(sic), the Illusory Pond and Life’s Submarine Emergence—A Review

Autor: Michael J. Russell

Publikováno v: Life, Vol 11, Iss 5, p 429 (2021)

The assumption that there was a “water problem” at the emergence of life—that the Hadean Ocean was simply too wet and salty for life to have emerged in it—is here subjected to geological and experimental reality checks. The “warm little pon

International audience; Fougerite, the natural green rust, first discovered in soils and universally considered as responsible for the blue-green colour of gleys and an indicator of reducing conditions, has been recently considered as a key mineral f

International audience; A possibly prominent role for Green Rust minerals in life's emergence is inferred from a comparison of their structural, mechano-dynamic and electrochemical properties and of the layout of bioenergetic, i.e. free energy conver

International audience; Fougerite is a naturally occurring green rust, that is, a layered double hydroxide (LDH) containing iron (Fe). Fougerite was identified in natural settings such as hydromorphic soils. It is one of the few inorganic materials w
