Cysteine Chemistry in Connection with Abiogenesis
European Journal of Organic Chemistry, 2020Theoretical and experimental work has been conducted about possible prebiotic syntheses of cysteine. Activated derivatives of this amino acid can oligomerize and polymerize to afford various poly‐thiazolines and cysteine‐rich chains.

Abiogenesis and the reverse Hofmeister effect [PDF]
Nature Chemistry, 2018 Bruce C. Gibb takes us on a journey through the physical and chemical evolution of planet Earth and suggests that the reverse Hofmeister effect, the phenomenon whereby poorly solvated ions associate in water, could be a powerful driving force towards the first hint of life on the rock we call home.

Abiogenesis and the Second Law of Thermodynamics
2020Abiogenesis, life arising from non-living matter, is reconsidered. A historic account is given from Darwin to the present with special consideration of the incipient relationship between quantum theory and life processes. Recent ideas relating to the spontaneous emergence of life are considered and evaluated, including the work on self-organizing ...

Nucleic acids: function and potential for abiogenesis
Quarterly Reviews of Biophysics, 2017AbstractThe emergence of functional cooperation between the three main classes of biomolecules – nucleic acids, peptides and lipids – defines life at the molecular level. However, how such mutually interdependent molecular systems emerged from prebiotic chemistry remains a mystery. A key hypothesis, formulated by Crick, Orgel and Woese over 40 year ago,

Abiogenesis-Biogenesis Transition in Evolutionary Cybernetic System [PDF]
Cybernetics and Systems, 2021 Biogenesis and abiogenesis stages of natural evolution are the well-known terms to characterize a quite different phases of life development on the Earth.

Perspectives on Science and Christian Faith, 2023
This article concludes a three-part series on abiogenesis that suggests meaningful configurations of organic components can arise spontaneously, leading to organisms that successfully survive and reproduce.

Abiogenesis: The Emergence of Life from Non-living Matter
2018The field of abiogenesis explores the mystery concerning how life arose on Earth from non-living matter. We must assume that this happened in accordance with the laws of physics and chemistry. How chemical evolution led to the appearance of self-replicating polynucleotides has not been determined, but significant progress has been made.

Rethinking Abiogenesis: Part II, Life as a Simplification of the Nonliving Universe
Perspectives on Science and Christian Faith, 2021In Part I, we argued that it may be useful, even important, to perceive the origin of life as a seamlessly continuous (and arguably incomplete) process, rather than any specific point in time or evolutionary history.1 Here we challenge another widespread
