Multiplicity of species in some replicative systems
, 1999 In an attempt to explain the uniqueness of the coding mechanism of living cells as contrasted with multi-species structure of ecosystems we examine two models of individuals with some replicative properties.

Prebiotic thiol-catalyzed thioamide bond formation
Geochemical TransactionsThioamide bonds are important intermediates in prebiotic chemistry. In cyanosulfidic prebiotic chemistry, they serve as crucial intermediates in the pathways that lead to the formation of many important biomolecules (e.g., amino acids).

A prebiotic basis for ATP as the universal energy currency
PLoS Biology, 2022 ATP is universally conserved as the principal energy currency in cells, driving metabolism through phosphorylation and condensation reactions. Such deep conservation suggests that ATP arose at an early stage of biochemical evolution. Yet purine synthesis

Influence of minerals on aldose formation during hydrothermal processes in meteorite parent bodies
Progress in Earth and Planetary ScienceVarious prebiotic organic compounds have been identified in meteorites. Understanding the origins of these compounds is essential to comprehending prebiotic chemistry in the early Solar System.

Impact contribution of prebiotic reactants to Earth [PDF]
It is proposed that the AIB amino acid at the K/T boundary were synthesized during entry of a comet. However, whether they were synthesized or supplied directly from space, the concentration of amino acids in the shallow K/T sea would have been about 10 ...

Autocatalytic Selection as a Driver for the Origin of Life
LifeDarwin’s theory of evolution by natural selection was revolutionary because it provided a mechanism by which variation could be selected. This mechanism can only operate on living systems and thus cannot be applied to the origin of life. Here, we propose
