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 ...

Cysteine Chemistry in Connection with Abiogenesis

European Journal of Organic Chemistry, 2020
Theoretical 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.

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 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.

Nucleic acids: function and potential for abiogenesis

Quarterly Reviews of Biophysics, 2017
AbstractThe 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,
