A synthetic approach to abiogenesis

Nature Methods, 2014
Synthetic biology seeks to probe fundamental aspects of biological form and function by construction (resynthesis) rather than deconstruction (analysis). Here we discuss how such an approach could be applied to assemble synthetic quasibiological systems able to replicate and evolve, illuminating universal properties of life and the search for its ...

A Bayesian Analysis of the Probability of the Origin of Life Per Site Conducive to Abiogenesis.

Astrobiology
The emergence of life from nonlife, or abiogenesis, remains a fundamental question in scientific inquiry. In this article, we investigate the probability of the origin of life (per conducive site) by leveraging insights from Earth's environments. If life

Frankenstein or a Submarine Alkaline Vent: Who Is Responsible for Abiogenesis?

Bioessays, 2018
Origin of life models based on “energized assemblages of building blocks” are untenable in principle. This is fundamentally a consequence of the fact that any living system is in a physical state that is extremely far from equilibrium, a condition it ...

Precambrian ELF and Abiogenesis

1974
In 1938, Oparin, in his book, “The Origin of Life”, proposed environmental conditions under which life or its chemical precursors could have been synthesized on the primitive Earth. Though unchanged in essential features, Oparin’s conditions have been subsequently refined.

Abiogenesis: can timeless processes be invoked to explain the emergence of life from inert matter?

Entropie : thermodynamique – énergie – environnement – économie
In the research on the origin of life, topics that can be considered reasonably shared by the generality of researchers are initially identified. The application of these principles to the results obtained with the mathematical model for the simulation ...

Abiogenesis as a theoretical challenge: Some reflections

Journal of Theoretical Biology, 2016
In this paper I will reflect on the intellectual rationale underlying the origin of life scientific research efforts by reconsidering some of its conceptual premises and difficulties.

Astrobiological Perspectives on Abiogenesis: Review of The Influence of Celestial Planetary Bodies on Prebiotic Chemistry

Journal of Eco Astronomy, 2019
The origin of life (abiogenesis) remains a fundamental question in astrobiology, bridging the gap between inorganic chemistry and emergent biological complexity.

Two Experiments in Abiogenesis

Inference: International Review of Science, 2016
Two new papers on prebiotic chemistry are reviewed by James Tour. The first claims to find further support for the RNA World hypothesis and the second suggests that nucleotide formation and selection may have been robust processes on the prebiotic Earth. Tour expresses skepticism on both counts.
