Autocatalytic Sets Arising in a Combinatorial Model of Chemical Evolution [PDF]
Life, 2022 The idea that chemical evolution led to the origin of life is not new, but still leaves open the question of how exactly it could have led to a coherent and self-reproducing collective of molecules.

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.

Chemical Evolution of a Bacterium’s Genome [PDF]
Angewandte Chemie - International Edition, 2011 We set out to develop a generic technology for evolving the chemical constitution of microbial populations by using the simplest possible algorithm. Extant living cells polymerize a restricted set of nucleic acid precursors, namely, four nucleoside triphosphates (UTP, CTP, ATP, GTP) and four deoxynucleoside triphosphates (dTTP, dCTP, dATP, dGTP ...

A recursive microfluidic platform to explore the emergence of chemical evolution [PDF]
Beilstein Journal of Organic Chemistry, 2017 We propose that a chemically agnostic approach to explore the origin of life, using an automated recursive platform based on droplet microfluidics, could be used to induce artificial chemical evolution by iterations of growth, speciation, selection, and ...

Retrocausality in Quantum Phenomena and Chemical Evolution
Information, 2016 The interplay between retrocausality and the time-reversal symmetry of the dynamical law of quantum mechanics underscores the significance of the measurement dynamics with the use of indivisible and discrete quantum particles to be mediated.

Primitive Photosynthetic Architectures Based on Self‐Organization and Chemical Evolution of Amino Acids and Metal Ions [PDF]
Advanced Science, 2018 The emergence of light‐energy‐utilizing metabolism is likely to be a critical milestone in prebiotic chemistry and the origin of life. However, how the primitive pigment is spontaneously generated still remains unknown.

Life, 2022 The origin of biopolymers is a central question in origins of life research. In extant life, proteins are coded linear polymers made of a fixed set of twenty alpha-L-amino acids.

Thioesters provide a plausible prebiotic path to proto-peptides
Nature Communications, 2022 One of the early processes enabling the origins of life is thought to be the condensation of building blocks into oligomers and polymers. In this article, the authors report the synthesis of thiodepsipeptides and HS-peptides under mild temperatures and ...

Mutually stabilizing interactions between proto-peptides and RNA
Nature Communications, 2020 Cooperative relationships are widespread among different classes of biopolymers and are predicted to have existed during emergence of life. This study shows that proto-peptides engage in mutually stabilizing interactions with RNA, providing support for ...
