The requirement of cellularity for abiogenesis [PDF]
Computational and Structural Biotechnology Journal, 2021 The history of modern biochemistry started with the cellular theory of life. By putting aside the holistic protoplasmic theory, scientists of the XX century were able to advance the functional classification of cellular components significantly. The cell

Dissipative Photochemical Abiogenesis of the Purines [PDF]
Entropy, 2022 We have proposed that the abiogenesis of life around the beginning of the Archean may have been an example of “spontaneous” microscopic dissipative structuring of UV-C pigments under the prevailing surface ultraviolet solar spectrum.

The Chemical Origin of Behavior is Rooted in Abiogenesis [PDF]
Life, 2012 We describe the initial realization of behavior in the biosphere, which we term behavioral chemistry. If molecules are complex enough to attain a stochastic element to their structural conformation in such as a way as to radically affect their function ...

The Dissipative Photochemical Origin of Life: UVC Abiogenesis of Adenine
Entropy, 2021 The non-equilibrium thermodynamics and the photochemical reaction mechanisms are described which may have been involved in the dissipative structuring, proliferation and complexation of the fundamental molecules of life from simpler and more common ...

The Informational Substrate of Chemical Evolution: Implications for Abiogenesis [PDF]
Life, 2019 A key aspect of biological evolution is the capacity of living systems to process information, coded in deoxyribonucleic acid (DNA), and used to direct how the cell works.

An objective Bayesian analysis of life's early start and our late arrival. [PDF]
Proc Natl Acad Sci U S A, 2020 Life emerged on the Earth within the first quintile of its habitable window, but a technological civilization did not blossom until its last. Efforts to infer the rate of abiogenesis, based on its early emergence, are frustrated by the selection effect ...

Potassium at the Origins of Life: Did Biology Emerge from Biotite in Micaceous Clay? [PDF]
Life, 2022 Intracellular potassium concentrations, [K+], are high in all types of living cells, but the origins of this K+ are unknown. The simplest hypothesis is that life emerged in an environment that was high in K+.

Amniotic Fluid and Ocean Water: Evolutionary Echoes, Chemical Parallels, and the Infiltration of Micro- and Nanoplastics [PDF]
ToxicsBackground: Abiogenesis is hypothesized to have occurred in the aquatic environments of the early Earth approximately 3.8–4.0 billion years ago, in oceans containing high concentrations of ions (Na+ ≈ 470 mmol/L, Cl− ≈ 545 mmol/L, Mg2+ ≈ 51–53 mmol/L ...

The hierarchical organization of autocatalytic reaction networks and its relevance to the origin of life. [PDF]
PLoS Computational Biology, 2022 Prior work on abiogenesis, the emergence of life from non-life, suggests that it requires chemical reaction networks that contain self-amplifying motifs, namely, autocatalytic cores.

The Coevolution of Biomolecules and Prebiotic Information Systems in the Origin of Life: A Visualization Model for Assembling the First Gene [PDF]
Life, 2022 Prebiotic information systems exist in three forms: analog, hybrid, and digital. The Analog Information System (AIS), manifested early in abiogenesis, was expressed in the chiral selection, nucleotide formation, self-assembly, polymerization ...
