Bayesian analysis of the astrobiological implications of life's early emergence on Earth
, 2012 Life arose on Earth sometime in the first few hundred million years after the young planet had cooled to the point that it could support water-based organisms on its surface.

Evolution of primordial planets in relation to the cosmological origin of life
, 2011 We explore the conditions prevailing in primordial planets in the framework of the HGD cosmologies as discussed by Gibson and Schild. The initial stages of condensation of planet-mass H-4He gas clouds in trillion-planet clumps is set at 300,000 yr (0.3My)

Prior Indigenous Technological Species
, 2017 One of the primary open questions of astrobiology is whether there is extant or extinct life elsewhere the Solar System. Implicit in much of this work is that we are looking for microbial or, at best, unintelligent life, even though technological ...

The grid method Beziers – d'Arcy-Thompson in the reconstruction of morphogenesis and abiogenesis: elementary biomimetic model [PDF]
Морфологія, 2011 We propose a new modification made in the morphology of biological imaging methods based on new types of components and nets. Shown its applicability not only in the comparative morphology and evolutionary and systematic, but also in abiogenetic studies.

Nitrogen heterocycles form peptide nucleic acid precursors in complex prebiotic mixtures
Scientific Reports, 2019 The ability to store information is believed to have been crucial for the origin and evolution of life; however, little is known about the genetic polymers relevant to abiogenesis.

A Field Trip to the Archaean in Search of Darwin’s Warm Little Pond
Life, 2016 Charles Darwin’s original intuition that life began in a “warm little pond” has for the last three decades been eclipsed by a focus on marine hydrothermal vents as a venue for abiogenesis.

Complexity, Information and Biological Organisation [PDF]
Interdisciplinary Description of Complex Systems, 2005 Regarding the widespread confusion about the concept and nature of complexity, information and biological organization, we look for some coordinated conceptual considerations corresponding to quantitative measures suitable to grasp the main ...

If two physical timescales are independent, i.e. they depend on different physics, then (statistically) there is no reason to believe that their values should be equal, even to an order of magnitude. The timescale for abiogenesis $τ_{AB}$, which depends primarily on prebiotic-chemistry, is expected to be independent of the planetary habitability ...
