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.

Undefining life's biochemistry: implications for abiogenesis. [PDF]
J R Soc Interface, 2022 In the mid-twentieth century, multiple Nobel Prizes rewarded discoveries of a seemingly universal set of molecules and interactions that collectively defined the chemical basis for life.

Origin of the RNA World in Cold Hadean Geothermal Fields Enriched in Zinc and Potassium: Abiogenesis as a Positive Fallout from the Moon-Forming Impact? [PDF]
LifeThe ubiquitous, evolutionarily oldest RNAs and proteins exclusively use rather rare zinc as transition metal cofactor and potassium as alkali metal cofactor, which implies their abundance in the habitats of the first organisms.

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.

The Dissipative Photochemical Origin of Life: UVC Abiogenesis of Adenine [PDF]
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 ...

A mechanism of abiogenesis based on complex reaction networks organized by seed-dependent autocatalytic systems [PDF]
, 2021 The complexity gap between the biotic and abiotic worlds has made explaining abiogenesis one of the hardest scientific questions. A promising strategy for addressing this problem is to identify features shared by abiotic and biotic chemical systems that ...

Abiogenesis through gradual evolution of autocatalysis into template‐based replication
FEBS Letters, 2022 How life emerged from inanimate matter is one of the most intriguing questions posed to modern science. Central to this research are experimental attempts to build systems capable of Darwinian evolution.

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+.

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 ...
