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.

Strong Evidence that Abiogenesis Is a Rapid Process on Earth Analogs.
AstrobiologyThe early start to life naively suggests that abiogenesis is a rapid process on Earth-like planets. However, if evolution typically takes ∼4 Gyr to produce intelligent life-forms like us, then the limited lifespan of Earth's biosphere (∼5-6 Gyr ...

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 ...

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.

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.

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
