On the Evolutionary History of the Twenty Encoded Amino Acids
Chemistry – A European Journal, Volume 28, Issue 55, October 4, 2022., 2022 Amino acids and proteins! “Unde venistis”? The answer to the question of where these (macro)molecules come from is told as a journey that starts with meteorites and ends with the origin of the genetic code. On this journey, which incorporates the citric acid cycle and glycolysis, molecular companions and fellow travelers appear on the scene, in ...

Evolution of Realistic Organic Mixtures for the Origins of Life through Wet–Dry Cycling
Sci, 2022 One of the challenges in understanding chemical evolution is the large number of starting organics and environments that were plausible on early Earth. Starting with realistic organic mixtures and using chemical analyses that are not biologically biased,

Fatty Acid Vesicles as Hard UV-C Shields for Early Life
Foundations, 2023 Theories on life’s origin generally acknowledge the advantage of a semi-permeable vesicle (protocell) for enhancing the chemical reaction–diffusion processes involved in abiogenesis.

On the Evolution of the Biological Framework for Insight
Philosophies, 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 ...

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

The Meaning of Technology and Religion in the Context of Teilhard de Chardin’s Theistic Evolution [PDF]
Bogoslovni Vestnik, 2023 One of the first pioneers to try to reconcile the Catholic doctrine of creation, salvation and redemption with the idea of evolution was the French Jesuit Pierre Teilhard de Chardin. He believed that humanity has an important role to play in the further

Additional Remarks on Abiogenesis [PDF]
Nature, 1873 SINCE my communication in NATURE, March 20, a further investigation of the subject has shown me that the experiments there recorded do not yet fully prove the reality of abiogenesis. My argumentation based on those experiments is liable to the following objection:—
