“…The third aspect, where the importance of the presence of iron-rich swelling clay minerals has been suggested is the formation of the first biopolymers on Earth surface (Feuillie et al, 2013;Meunier et al, 2010;Pedreira-Segade et al, 2016). A series of synthetic iron-rich tri-octahedral clay minerals with well-defined characteristics, such as particle size and layer charge could contribute to understanding the adsorption and retention phenomena of these molecules on clay surfaces.…”

Examples in materials science and in geology show an interest for iron-rich tri-octahedral clay mineral synthesis in large amounts and with well-defined characteristics. This review summarizes previously reported methods and conditions for iron-rich tri-octahedral clay mineral synthesis. Two approaches of hydrothermal synthesis have been applied: using gel or solid precursors. The most common synthesis approach is the hydrothermal synthesis using gel precursor. The synthesis of 1:1 type clay minerals were performed in reducing conditions in neutral or alkaline pH at various temperature and time ranges. The experimental conditions for 2:1 type clay mineral synthesis were in most cases similar to 1:1 type clay minerals, with in addition acidic pH and oxidizing conditions. The most commonly used methods for identifying and characterizing these minerals are X-ray diffraction, infra-red and Mössbauer spectroscopies as well as transmission electron microscopy. The thermodynamic stability of synthesized phases, as well as the reason for elements adopting a definite configuration and distribution in solid phase remain open questions.

“…The longevity of mineral adsorbed DNA depends on a range of factors where in particular mineral species ( Lorenz and Wackernagel, 1987 ; Cao et al, 2011 ; Michalkova et al, 2011 ; Feuillie et al, 2013 ; Canhisares-Filho et al, 2015 ; Pedreira-Segade et al, 2016 ), background ions ( Lorenz and Wackernagel, 1987 ; Nguyen and Chen, 2007 ; Lu et al, 2010 ), salinity, and pH ( Greaves and Wilson, 1969 ; Saeki et al, 2010 ; Michalkova et al, 2011 ; Feuillie et al, 2015 ; Maity et al, 2015 ) determine the DNA adsorption capacity of a mineral. Depending on the crystalline structure and composition, the surface charge of most minerals changes as a function of pH.…”

“…Above ∼pH 2, the deprotonated and hence negatively charged phosphate moieties of the DNA can adsorb to negatively charged mineral surfaces through polyvalent cations (Ca 2+ , Mg 2+ , and Al 3+ ) which make a “bridge” between two negative charges. These charge relationships between DNA and minerals as a function of pH make adsorption and desorption of DNA very sensitive to the geochemical characteristics of the environment (solution composition, oxygen fugacity, temperature, and pH) ( Cao et al, 2011 ; Michalkova et al, 2011 ; Feuillie et al, 2013 ; Pedreira-Segade et al, 2016 ; Biondi et al, 2017 ) and at neutral pH conditions clay edges and oxides can be considered to have a stronger electrostatic interaction with the negatively charged DNA moieties. These charge relationships are also likely to affect degradation by biological factors.…”

A number of studies have highlighted that adsorption to minerals increases DNA longevity in the environment. Such DNA-mineral associations can essentially serve as pools of genes that can be stored across time. Importantly, this DNA is available for incorporation into alien organisms through the process of horizontal gene transfer (HGT). Here we argue that minerals hold an unrecognized potential for successfully transferring genetic material across environments and timescales to distant organisms and hypothesize that this process has significantly influenced the evolution of life. Our hypothesis is illustrated in the context of the evolution of early microbial life and the oxygenation of the Earth’s atmosphere and offers an explanation for observed outbursts of evolutionary events caused by HGT.
