The Informational Substrate of Chemical Evolution: Implications for Abiogenesis [PDF]
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.

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

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

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

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

Synthesis and Characterization of Amino Acid Decyl Esters as Early Membranes for the Origins of Life
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 Future of Origin of Life Research: Bridging Decades-Old Divisions
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?
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.
