10 cze 2020 · Glavin et al. review the enantiomeric and isotopic compositions and distributions of molecules found in meteorites and propose a set of criteria for The Search for Chiral Asymmetry as a Potential Biosignature in our Solar System.
1 lut 2008 · The present paper has a different focus: Can we understand the emergence of life as a process based on physics and chemistry, i.e. can we find a distinct continuous sequence of hypothetical physicochemical steps finally leading to a bio-like genetic apparatus, the basic machinery of bio-systems?
4 dni temu · The Game of Life (GoL) is a paradigmatic computer simulation that exhibits the emergence of complex properties of the whole from relatively simple sets of heuristic rules operating at lower organizational levels. Therefore, it is widely understood as a valuable tool for investigating global properties of evolutionary processes. Cognizant of refined concepts that emerged in recent debates on ...
19 wrz 2022 · In this concept paper, we would like to concentrate on this specific topic, and introduce the symmetry based kinematic theory (SBKT) to explain the formation and evolution of crystal facets. It is a crystallographic theory based on the classical crystal growth concepts developed to illustrate the shape evolution during the NC growth.
14 mar 2022 · Researchers believe symmetric and simple structures are common because evolution favors simple “algorithms” or instruction sets for creating these structures. From sunflowers to starfish, symmetry appears everywhere in biology.
8 sie 2022 · A new proposal for the origin of asymmetry and, by extension, the origin of life uses spin-polarized electrons to induce enantioselective chemistry in the prebiotic world.
First, directional asymmetry, an evolutionary novelty, arose from nonheritable origins almost as often as from mutations, implying that genetic assimilation (“phenotype precedes genotype”) is a common mode of evolution.
