The Chemical Origin of Behavior is Rooted in Abiogenesis [PDF]
Life, 2012 We describe the initial realization of behavior in the biosphere, which we term behavioral chemistry. If molecules are complex enough to attain a stochastic element to their structural conformation in such as a way as to radically affect their function ...

Molecular Imprinting: The missing piece in the puzzle of abiogenesis? [PDF]
arXiv, 2018 In a neglected 2005 paper, Nobel Laureate Paul Lauterbur proposed that molecular imprinting in amorphous materials -- a phenomenon with an extensive experimental literature -- played a key role in abiogenesis. The present paper builds on Lauterbur's idea to propose imprint-mediated templating (IMT), a mechanism for prebiotic peptide replication that ...

Abiogenesis through gradual evolution of autocatalysis into template‐based replication
FEBS Letters, Volume 597, Issue 3, Page 344-379, February 2023., 2022 In this review, we examine how rudimentary forms of evolution may have started in autocatalytic RNA networks and subsequently led to the appearance of RNA replicases, allowing life to emerge from inanimate matter. How life emerged from inanimate matter is one of the most intriguing questions posed to modern science.

Potassium at the Origins of Life: Did Biology Emerge from Biotite in Micaceous Clay? [PDF]
Life, 2022 Intracellular potassium concentrations, [K+], are high in all types of living cells, but the origins of this K+ are unknown. The simplest hypothesis is that life emerged in an environment that was high in K+.

The hierarchical organization of autocatalytic reaction networks and its relevance to the origin of life. [PDF]
PLoS Computational Biology, 2022 Prior work on abiogenesis, the emergence of life from non-life, suggests that it requires chemical reaction networks that contain self-amplifying motifs, namely, autocatalytic cores.

Emergence of life in an inflationary universe. [PDF]
Sci Rep, 2020 Abiotic emergence of ordered information stored in the form of RNA is an important unresolved problem concerning the origin of life. A polymer longer than 40--100 nucleotides is necessary to expect a self-replicating activity, but the formation of such a long polymer having a correct nucleotide sequence by random reactions seems statistically unlikely.

Synthesis and Characterization of Amino Acid Decyl Esters as Early Membranes for the Origins of Life [PDF]
Membranes, 2022 Understanding how membrane forming amphiphiles are synthesized and aggregate in prebiotic settings is required for understanding the origins of life on Earth 4 billion years ago.

The Coevolution of Biomolecules and Prebiotic Information Systems in the Origin of Life: A Visualization Model for Assembling the First Gene [PDF]
Life, 2022 Prebiotic information systems exist in three forms: analog, hybrid, and digital. The Analog Information System (AIS), manifested early in abiogenesis, was expressed in the chiral selection, nucleotide formation, self-assembly, polymerization ...

Abiogenesis: the Carter argument reconsidered [PDF]
, 2022 The observation of life on Earth is commonly believed to be uninformative regarding the probability of abiogenesis on other Earth-like planets. This belief is based on the selection effect of our existence.

The HOMO-LUMO Gap as Discriminator of Biotic from Abiotic Chemistries [PDF]
LifeLow-molecular-mass organic chemicals are widely discussed as potential indicators of life in extraterrestrial habitats. However, demarcation lines between biotic chemicals and abiotic chemicals have been difficult to define.
