“…The origin of life (or abiogenesis) is among the most intriguing questions in science [64]. Although it is not possible to know all the details of this process, some scientific hypotheses attempt to explain the synthesis of the molecules which were necessary for the emergence of primitive forms of life in planet Earth 3.8 billion years ago [65] as deriving from a reducing atmosphere (Miller's experiment [66]), meteorites impacts [67] or from metal sulfides in deep-sea hydrothermal vents, as explained in the famous article of Russel [68].…”

Layered Double Hydroxides (LDHs) are a relevant class of inorganic lamellar nanomaterials that have attracted significant interest in life science-related applications, due to their highly controllable synthesis and high biocompatibility. Under a general point of view, this class of materials might have played an important role for the origin of life on planet Earth, given their ability to adsorb and concentrate life-relevant molecules in sea environments. It has been speculated that the organic–mineral interactions could have permitted to organize the adsorbed molecules, leading to an increase in their local concentration and finally to the emergence of life. Inspired by nature, material scientists, engineers and chemists have started to leverage the ability of LDHs to absorb and concentrate molecules and biomolecules within life-like compartments, allowing to realize highly-efficient bioinspired platforms, usable for bioanalysis, therapeutics, sensors and bioremediation. This review aims at summarizing the latest evolution of LDHs in this research field under an unprecedented perspective, finally providing possible challenges and directions for future research.

“…The pores generated in minerals that precipitate at the contact of heated water vents with the surrounding ocean water would ensure the concentration of organic compounds by thermophoresis (Baaske et al, 2007). Porous structures generated by mineral sulphides created the conditions of protometabolism and protected the first proto-organisms of "dilution and other damage" (Lambert, 2015). Deamer et al (2006) believe that a more suitable environment for life emergence would be an aqueous phase with moderate temperature oscillations (below 60°C), a pH close to neutral and very low (submillimolar) concentrations of divalent cations.…”

The paper is a synthesis of the information collected so far on the origin and evolution of life on Earth. The life appearance and its evolution is correlated to matter evolution in univers: Big Bang, inorganic, organic, prebiotic, unicellular and multicellular stages. Concerning prebiotic stage in life evolution we present our theory based on syntone chemistry. Three syntones-methylene, nitrene and carbon monoxid carried by molecular nitrogen at law temperature could furnish the prebiotic bricks (sugars, lipids, proteins) at the contact to primary atmosphere components. Also, we think that these syntones could be considered as sources of great number of organic molecules. All organisms on Earth descend from a last universal common ancestor (LUCA). Two branches were derived from LUCA: one led to bacteria and the other to archaea and eukaryotes. The appearance of photosynthesis determined a transition from the oxygen-free atmosphere to the oxic atmosphere. Due to a series of endosymbioses, Eukaryotes emerged as organisms with nucleated cells and aerobic metabolism (which significantly increased the efficiency of cellular energy production). At about the same time appeared the first multicellular organisms. The paper also presents other important moments in the evolution of life on Earth, including the major biological crises in certain periods, resulting in the mass extinction of some groups of organisms. The evolution of the living world on Earth culminated with the emergence of man, the most complex being with language, superior thinking, emotions, creativity, etc.

“…Ice appears to be the less effective protector since it is easily perishable by climatic warming. In regard to molecular biosignatures, molecular binding to minerals, like phyllosilicates [60,73,74] and Al-Fe oxyhydroxides [115], has shown to enhance preservation. Amorphous materials have also demonstrated some preservation potential that can be ascribed to the possibility to incorporate and protect molecules within their porous structure.…”

Minerals might have played critical roles for the origin and evolution of possible life forms on Mars. The study of the interactions between “building blocks of life” and minerals relevant to Mars mineralogy under conditions mimicking the harsh Martian environment may provide key insight into possible prebiotic processes. Therefore, this contribution aims at reviewing the most important investigations carried out so far about the catalytic/protective properties of Martian minerals toward molecular biosignatures under Martian-like conditions. Overall, it turns out that the fate of molecular biosignatures on Mars depends on a delicate balance between multiple preservation and degradation mechanisms often regulated by minerals, which may take place simultaneously. Such a complexity requires more efforts in simulating realistically the Martian environment in order to better inspect plausible prebiotic pathways and shed light on the nature of the organic compounds detected both in meteorites and on the surface of Mars through in situ analysis.
