“…By contrast, some molecular biologists view the details of the genetic code as a "frozen accident" (Crick 1968, Freeland & Hurst 1998; i.e., combinations of three nucleobases (codons) that correspond to specific amino acids may be largely the result of historical contingency. However, subsequent analyses and ongoing lively debates continue to assess possible deterministic aspects of the genetic code (Gusev & Schulze-Makuch 2004, Vestigian et al 2006, Delarue 2007, Carter 2008, as well as protein structure and function (Harms & Thornton 2014).…”

Four factors contribute to the roles played by chance and necessity in determining mineral distribution and diversity at or near the surfaces of terrestrial planets: (1) crystal chemical characteristics; (2) mineral stability ranges; (3) the probability of occurrence for rare minerals; and (4) stellar and planetary stoichiometries in extrasolar systems.The most abundant elements generally have the largest numbers of mineral species, as modeled by relationships for Earth's upper continental crust (E) and the Moon (M), respectively: LogðN E Þ ¼ 0:22 LogðC E Þ þ 1:70 ðR 2 ¼ 0:34Þð4861 minerals; 72 elementsÞ LogðN M Þ ¼ 0:19 LogðC M Þ þ 0:23 ðR 2 ¼ 0mineral species await discovery or could have occurred at some point in Earth's history, only to be subsequently lost by burial, erosion, or subduction-i.e., much of Earth's mineral diversity associated with rare species results from stochastic processes.Measurements of stellar stoichiometry reveal that stars can differ significantly from the Sun in relative abundances of rock-forming elements, which implies that bulk compositions of some extrasolar Earth-like planets likely differ significantly from those of Earth, particularly if the fractionation processes in evolving stellar nebulas and planetary differentiation are factored in. Comparison of Earth's upper continental crust and the Moon shows that differences in element ratios are reflected in ratios of mineral species containing these elements.In summary, although deterministic factors control the distribution of the most common rock-forming minerals in Earth's upper continental crust and on the Moon, stochastic processes play a significant role in the diversity of less common minerals. Were Earth's history to be replayed, and thousands of mineral species discovered and characterized anew, it is probable that many of those minerals would differ from species known today.

The code is meaningless unless translated. (Monod 1971, 143) We address issues of a description of the origin and evolution of the genetic code from the semiotics standpoint. Developing the concept of codepoiesis introduced by M. Barbieri, a new idea of semio-poiesis is proposed. Semio-poiesis, a recursive auto-referential processing of a semiotic system, becomes a form of organization of the bio-world when and while notions of meaning and aiming are introduced into it. The description of the genetic code as a semiotic system (grammar and vocabulary) allows us to apply the method of internal reconstruction to it: on the basis of heterogeneity and irregularity of the current state, to explicate possible previous states and various ways of forming coding and textualization mechanisms. The revealed patterns and irregularities are consistent with hypotheses about the origin and evolution of the genetic code.

“…We have called this class the hidden class and results about it showing a possible connection with a graph theory of anti-codon classes will be published elsewhere. Moreover, the three anti-symmetric transformations together with the identity have a group structure, indeed, they form a 4-Klein group called Klein V group (Jimenez-Montaño, 1999;Gusev and Schulze-Makuch, 2004). Second, denoted by p p the probability of occurrence of an odd codon in a real coding sequence, the probability after application of the Y-R transformation will be 1 − p p .…”

Biosemiotics

Aims and Scope of the SeriesCombining research approaches from biology, philosophy and linguistics, the emerging field of biosemiotics proposes that animals, plants and single cells all engage in semiosis -the conversion of physical signals into conventional signs. This has important implications and applications for issues ranging from natural selection to animal behaviour and human psychology, leaving biosemiotics at the cutting edge of the research on the fundamentals of life.The Springer book series Biosemiotics draws together contributions from leading players in international biosemiotics, producing an unparalleled series that will appeal to all those interested in the origins and evolution of life, including molecular and evolutionary biologists, ecologists, anthropologists, psychologists, philosophers and historians of science, linguists, semioticians and researchers in artificial life, information theory and communication technology.
