55Memory and Learning as Key Competences of Living OrganismsIn Baluska Frantisek, Gagliano Monica & Guenther Witzany (eds.), Memory and Learning in Plants, Springer. pp. 1-16. 2018.Organisms that share the capability of storing information about experiences in the past have an actively generated background resource on which they can compare and evaluate more recent experiences in order to quickly or even better react than in previous situations. This is an essential competence for all reaction and adaptation purposes of living organisms. Such memory/learning skills can be found from akaryotes up to unicellular eukaryotes, fungi, animals and plants, although until recently,…Read more

87Quasispecies ProductivityThe Science of Nature (Naturwissenschaften) 111 11. 2024.Abstract The quasispecies theory is a helpful concept in the explanation of RNA virus evolution and behaviour, with a relevant impact on methods used to fight viral diseases. It has undergone some adaptations to integrate new empirical data, especially the non-deterministic nature of mutagenesis, and the variety of behavioural motifs in cooperation, competition, communication, innovation, integration, and exaptation. Also, the consortial structure of quasispecies with complementary roles of memo…Read more

251How Viruses Made Us Humans (review)In Nathalie Gontier, Andy Lock & Chris Sinha (eds.), The Oxford Handbook of Human Symbolic Evolution, Oup. pp. 1-20. 2024.Current research on the origin of DNA and RNA, viruses, and mobile genetic elements prompts a re-evaluation of the origin and nature of genetic material as the driving force behind evolutionary novelty. While scholars used to think that novel features resulted from random genetic mutations of an individual’s specific genome, today we recognize the important role that acquired viruses and mobile genetic elements have played in introducing evolutionary novelty within the genomes of species. Viral …Read more

253To the End of Dogmatism in Molecular BiologyBiosemiotics 14 (1): 67-72. 2021.Denis Nobel looks at four important misinterpretations of molecular biology concerning evolutionary processes and demonstrates that the new synthesis today looks rather outdated. The modern synthesis is nearly 80 years old. The proponents who worked out the modern synthesis had no access to the current knowledge on cell biology, genetics, epigenetics, RNA biology and virology. Therefore this contribution adds several aspects which Nobel’s article does not explicitly mention, providing some examp…Read more

1562What is Life?Frontiers in Astronomy and Space Sciences 7 1-13. 2020.In searching for life in extraterrestrial space, it is essential to act based on an unequivocal definition of life. In the twentieth century, life was defined as cells that self-replicate, metabolize, and are open for mutations, without which genetic information would remain unchangeable, and evolution would be impossible. Current definitions of life derive from statistical mechanics, physics, and chemistry of the twentieth century in which life is considered to function machine like, ignoring …Read more

259From the "'logic of Molecular Syntax' to Molecular Pragmatism. Explanatory deficits in Manfred Eigen's concept of language and communication.Evolution and Cognition 2 (1): 148-168. 1995.Manfred Eigen employs the terms language and communication to explain key recombination processes of DNA as well as to explain the self-organization of human language and communication: Life processes as well as language and communication processes are governed by the logic of a molecular syntax, which is the exact depiction of a principally formalizable reality. The author of the present contribution demonstrates that this view of Manfred Eigen’s cannot be sufficiently substantiated and that it…Read more

1365That is life: communicating RNA networks from viruses and cells in continuous interactionAnnals of the New York Academy of Sciences 1-16. 2019.All the conserved detailed results of evolution stored in DNA must be read, transcribed, and translated via an RNAmediated process. This is required for the development and growth of each individual cell. Thus, all known living organisms fundamentally depend on these RNA-mediated processes. In most cases, they are interconnected with other RNAs and their associated protein complexes and function in a strictly coordinated hierarchy of temporal and spatial steps (i.e., an RNA network). Clearly, al…Read more

78The Viral Origins of Telomeres and Telomerases and their Important Role in Eukaryogenesis and Genome MaintenanceBiosemiotics 1 (2): 191-206. 2008.Whereas telomeres protect terminal ends of linear chromosomes, telomerases identify natural chromosome ends, which differ from broken DNA and replicate telomeres. Although telomeres play a crucial role in the linear chromosome organization of eukaryotic cells, their molecular syntax most probably descended from an ancient retroviral competence. This indicates an early retroviral colonization of large double-stranded DNA viruses, which are putative ancestors of the eukaryotic nucleus. This contri…Read more

532Key Levels of BiocommunicationIn Richard Gordon & Joseph Seckbach (eds.), Biocommunication: Sign-mediated interactions between cells and organisms, World Scientific. pp. 37-61. 2016.Organisms actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between “self” and “non-self.” Current empirical data on all domains of life indicate that unicellular organisms such as bacteria, archaea, giant viruses, and protozoa as well as multicellular organisms such a…Read more

809Artificial and Natural Genetic Information ProcessingIn Mark Burgin & Wolfgang Hofkirchner (eds.), Information Studies and the Quest for Transdisciplinarity, World Scientific. pp. 523-547. 2017.Conventional methods of genetic engineering and more recent genome editing techniques focus on identifying genetic target sequences for manipulation. This is a result of historical concept of the gene which was also the main assumption of the ENCODE project designed to identify all functional elements in the human genome sequence. However, the theoretical core concept changed dramatically. The old concept of genetic sequences which can be assembled and manipulated like molecular bricks has probl…Read more

435Two genetic codes: Repetitive syntax for active non-coding RNAs; non-repetitive syntax for the DNA archivesCommunicative and Integrative Biology 10 (2). 2017.Current knowledge of the RNA world indicates 2 different genetic codes being present throughout the living world. In contrast to non-coding RNAs that are built of repetitive nucleotide syntax, the sequences that serve as templates for proteins share—as main characteristics—a non-repetitive syntax. Whereas non-coding RNAs build groups that serve as regulatory tools in nearly all genetic processes, the coding sections represent the evolutionarily successful function of the genetic information stor…Read more

Noncoding RNAs: Persistent Viral Agents as Modular Tools for Cellular NeedsAnnals of the New York Academy of Sciences 1178 244-267. 2009.It appears that all the detailed steps of evolution stored in DNA that are read, transcribed, and translated in every developmental and growth process of each individual cell depend on RNA-mediated processes, in most cases interconnected with other RNAs and their associated protein complexes and functions in a strict hierarchy of temporal and spatial steps. Life could not function without the key agents of DNA replication, namely mRNA, tRNA, and rRNA. Not only rRNA, but also tRNA and the process…Read more
