A prebiotic template-directed peptide synthesis based on amyloids
Nature Communications, 2018 Amyloids may have played an important role in prebiotic molecular evolution but understanding replication of such information-coding molecules is still a problem.

Life's Chirality From Prebiotic Environments
, 2012 A key open question in the study of life is the origin of biomolecular homochirality: almost every life-form on Earth has exclusively levorotary amino acids and dextrorotary sugars. Will the same handedness be preferred if life is found elsewhere?

Extending the Modern Synthesis: The evolution of ecosystems [PDF]
, 2010 The Modern Evolutionary Synthesis formalizes the role of variation, heredity, differential reproduction and mutation in population genetics. Here we explore a mathematical structure, based on the asymptotic limit theorems of information theory, that ...

Length and sequence relaxation of copolymers under recombination reactions
, 2017 We describe the kinetics and thermodynamics of copolymers undergoing recombination reactions, which are important for prebiotic chemistry. We use two approaches: the first one, based on chemical rate equations and the mass-action law describes the ...

Three phases in the evolution of the standard genetic code: how translation could get started [PDF]
, 2007 A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like.

A Necessary Condition for Coexistence of Autocatalytic Replicators in a Prebiotic Environment
Life, 2013 A necessary, but not sufficient, mathematical condition for the coexistence of short replicating species is presented here. The mathematical condition is obtained for a prebiotic environment, simulated as a fed-batch reactor, which combines monomer ...

Life, 2019 Information is the currency of life, but the origin of prebiotic information remains a mystery. We propose transitional pathways from the cosmic building blocks of life to the complex prebiotic organic chemistry that led to the origin of information ...
