Prebiotic network evolution: six key parameters
Molecular BioSystems, 2015Abstract The origins of life likely required the cooperation among a set of molecular species interacting in a network. If so, then the earliest modes of evolutionary change would have been governed by the manners and mechanisms by which networks change their compositions over time.

Pathways for the formation and evolution of peptides in prebiotic environments
Chemical Society Reviews, 2012α-Amino acids are easily accessible through abiotic processes and were likely present before the emergence of life. However, the role they could have played in the process remains uncertain. Chemical pathways that could have brought about features of self-organization in a peptide world are considered in this review and discussed in relation with their

Network Theory in Prebiotic Evolution
2018One of the most challenging aspect of origins of life research is that we do not know precisely what life is. In recent years, the use of network theory has revolutionized our understanding of living systems by permitting a mathematical framework for understanding life as an emergent, collective property of many interacting entities.

Is There an Optimal Level of Open-Endedness in Prebiotic Evolution?
Origins of Life and Evolution of Biospheres, 2012In this paper we explore the question of whether there is an optimal set up for a putative prebiotic system leading to open-ended evolution (OEE) of the events unfolding within this system. We do so by proposing two key innovations. First, we introduce a new index that measures OEE as a function of the likelihood of events unfolding within a universe ...

Nonequilibrium steady states in a model for prebiotic evolution
Physical Review E, 2014Some statistical features of steady states of a Kauffman-like model for prebiotic evolution are reported from computational studies. We postulate that the interesting "lifelike" states will be characterized by a nonequilibrium distribution of species and a time variable species self-correlation function.

From chemical to prebiotic evolution
2001We have seen in Chapter 1 that the biogenic elements were formed in stellar cores and later were expelled by the host star through stellar explosions l and other processes. Subsequently, they combine in the atmospheres of evolved stars to form diatomic and triatomic molecules that are to have transcendental consequences in the subsequent stages of ...

Prebiotic Evolution and Self-Assembly of Nucleic Acids
ACS Nano, 2018Prebiotic evolution is the stage that is assumed to have taken place prior to the emergence of the first living entities, during which time the abiotic synthesis of monomers, oligomers, and supramolecular systems that led to the hypothesized RNA world occurred.

Computer simulations of prebiotic evolution.
Pacific Symposium on Biocomputing. Pacific Symposium on Biocomputing, 1998This paper is a review of our previous work on the field of possible ways of prebiotic evolution. We propose an algorithm providing sequences of model proteins with rapid folding into a given native conformation. Thermodynamical analysis shows that the increase in speed is matched by an increase in stability: the evolved sequences are much more stable ...
