The Theory of Evolution is Not an Explanation for the Origin of Life [PDF]

open access: yes, 2010
The propagation of misconceptions about the theory of biological evolution must be addressed whenever and wherever they are encountered. The recent article by Paz-y-Mino and Espinoza in this journal contained several such misconceptions, including: that ...

On the Evolution of the Biological Framework for Insight

open access: yesPhilosophies, 2021
The details of abiogenesis, to date, remain a matter of debate and constitute a key mystery in science and philosophy. The prevailing scientific hypothesis implies an evolutionary process of increasing complexity on Earth starting from (self ...

Protection of liposomes by ferric salts against the UV damage and its implications for the origin of life

open access: yesFrontiers in Astronomy and Space Sciences
Previously, we presented a hypothesis on the Darwinian evolution of liposomes that relies only on natural and ever-present phenomena: solar UV radiation, day/night cycle, gravity, and the formation/release of amphiphiles in aqueous media.

Field-control, phase-transitions, and life's emergence [PDF]

open access: yes, 2012
Instances of critical-like characteristics in living systems at each organizational level as well as the spontaneous emergence of computation (Langton), indicate the relevance of self-organized criticality (SOC).

An Ontological Solution to the Mind-Body Problem [PDF]

open access: yes, 2017
I argue for an idealist ontology consistent with empirical observations, which seeks to explain the facts of nature more parsimoniously than physicalism and bottom-up panpsychism.

The Impact of Salts on Single Chain Amphiphile Membranes and Implications for the Location of the Origin of Life

open access: yesLife, 2017
One of the key steps in the origins of life was the formation of a membrane to separate protocells from their environment. These membranes are proposed to have been formed out of single chain amphiphiles, which are less stable than the dialkyl lipids ...

Simple Ion–Gas Mixtures as a Source of Key Molecules Relevant to Prebiotic Chemistry

open access: yesMolecules, 2021
Very simple chemistry can result in the rapid and high-yield production of key prebiotic inorganic molecules. The two reactions investigated here involve such simple systems, (a) carbon disulfide (CS2) and acetate (CH3COO¯) and (b) sulfur dioxide (SO2 ...

Dependence of Biological Activity on the Surface Water Fraction of Planets

open access: yes, 2019
One of the unique features associated with the Earth is that the fraction of its surface covered by land is comparable to that spanned by its oceans and other water bodies.

Molecular basis of Arginine and Lysine DNA sequence-dependent thermo-stability modulation.

open access: yesPLoS Computational Biology, 2022
We have used a variety of theoretical and experimental techniques to study the role of four basic amino acids-Arginine, Lysine, Ornithine and L-2,4-Diaminobutyric acid-on the structure, flexibility and sequence-dependent stability of DNA.
