Xeno Amino Acids: A Look into Biochemistry as We Do Not Know It

open access: yesLife, 2023
Would another origin of life resemble Earth’s biochemical use of amino acids? Here, we review current knowledge at three levels: (1) Could other classes of chemical structure serve as building blocks for biopolymer structure and catalysis?

Towards an evolutionary theory of the origin of life based on kinetics and thermodynamics [PDF]

open access: yesOpen Biology, 2013
A sudden transition in a system from an inanimate state to the living state—defined on the basis of present day living organisms—would constitute a highly unlikely event hardly predictable from physical laws.

The “Odd Inches”: Moby-Dick’s Fossil Record and Melville’s Admeasured Time

open access: yesMiranda: Revue Pluridisciplinaire du Monde Anglophone, 2022
This paper considers the measurements of fossils and markers of geologic time as they appear throughout Moby-Dick, complicating histories of bodies and their remainders. Looking for instances where Ishmael’s measurements fall short or fail to include the

The Future of Origin of Life Research: Bridging Decades-Old Divisions

open access: yesLife, 2020
Research on the origin of life is highly heterogeneous. After a peculiar historical development, it still includes strongly opposed views which potentially hinder progress.

Did Homocysteine Take Part in the Start of the Synthesis of Peptides on the Early Earth?

open access: yesBiomolecules, 2022
Unlike its shorter analog, cysteine, and its methylated derivative, methionine, homocysteine is not today a proteinogenic amino acid. However, this thiol containing amino acid is capable of forming an activated species intramolecularly.

The origin of life: what we know, what we can know and what we will never know [PDF]

open access: yesOpen Biology, 2013
The origin of life (OOL) problem remains one of the more challenging scientific questions of all time. In this essay, we propose that following recent experimental and theoretical advances in systems chemistry, the underlying principle governing the ...

Biblical Perspectives as a Guide to Research on Life’s Origin and History

open access: yesReligions, 2023
The more than thirty spacetime theorems developed over the past five decades establish that the universe and its spacetime dimensions have emerged from a cause/causal agent beyond the cosmos.

Straightforward Creation of Possibly Prebiotic Complex Mixtures of Thiol-Rich Peptides

open access: yesLife, 2023
At the origin of life, extremely diverse mixtures of oligomers and polymers could be obtained from relatively simple molecular bricks. Here, we present an example of the polymerization of two amidonitriles derived from cysteine, Cys-Ala-CN and Cys-Met-CN.
