, 1974 The origin of life is in a sense a genetic problem, for, as H. J. Muller pointed out many years ago, the essential attribute that identifies living matter is its capacity to replicate itself and its variants (1). Because this uniquely biological property

Energetics in a model of prebiotic evolution
Physical Review E, 2017 Previously we reported [A. Wynveen et al., Phys. Rev. E 89, 022725 (2014)PLEEE81539-375510.1103/PhysRevE.89.022725] that requiring that the systems regarded as lifelike be out of chemical equilibrium in a model of abstracted polymers undergoing ligation and scission first introduced by Kauffman [S.

Temporal nanofluid environments induce prebiotic condensation in water
Communications Chemistry, 2023 Water is a problem in understanding chemical evolution towards life’s origins on Earth. Although all known life is being based on water key prebiotic reactions are inhibited by it.

Biology Direct, 2012 Background Our current understanding of evolution is so tightly linked to template-dependent replication of DNA and RNA molecules that the old idea from Oparin of a self-reproducing 'garbage bag' ('coacervate') of chemicals that predated fully-fledged ...

Parasites Sustain and Enhance RNA-Like Replicators through Spatial Self-Organisation. [PDF]
PLoS Computational Biology, 2016 In a prebiotic RNA world, parasitic behaviour may be favoured because template dependent replication happens in trans, thus being altruistic. Spatially extended systems are known to reduce harmful effects of parasites. Here we present a spatial system to

Origin of symbol-using systems: speech, but not sign, without the semantic urge [PDF]
, 2014 Natural language—spoken and signed—is a multichannel phenomenon, involving facial and body expression, and voice and visual intonation that is often used in the service of a social urge to communicate meaning.

Prebiotic Reaction Networks in Water
Life, 2020 A prevailing strategy in origins of life studies is to explore how chemistry constrained by hypothetical prebiotic conditions could have led to molecules and system level processes proposed to be important for life’s beginnings. This strategy has yielded

Effect of migration in a diffusion model for template coexistence in protocells [PDF]
, 2014 The compartmentalization of distinct templates in protocells and the exchange of templates between them (migration) are key elements of a modern scenario for prebiotic evolution.

Beilstein Journal of Organic Chemistry, 2017 Conceiving the process of biogenesis as the evolutionary development of highly dynamic and integrated protocell populations provides the most appropriate framework to address the difficult problem of how prebiotic chemistry bridged the gap to full ...

Twenty years of "Lipid World": a fertile partnership with David Deamer [PDF]
, 2019 "The Lipid World" was published in 2001, stemming from a highly effective collaboration with David Deamer during a sabbatical year 20 years ago at the Weizmann Institute of Science in Israel.
