VI. Earth Life Emergence: Development of Body, Brain, Selves and Societies
2. The Deep Affinity of Genomes and Languages
Around 1970, the linguist Roman Jakobson and biopsychologist Jean Piaget opined that these prime informational domains ought to have common similarities. The common phrase Book of Life, along with analogous usage of language terms in genetics went on even earlier. Over the subsequent decades, as gathered here, the parallels grew in veracity and value, often serving as insightful comparisons. We now enter this 2016 section because several recent contributions strongly confirm, as naturally should be, an innate similarity. A March 2016 issue of the Philosophical Transactions of the Royal Society A on “DNA as Information” (search Cartwright) braces this result by novel rootings of genome phenomena in nature’s mathematics, physics and chemistry. As our worldwise humankinder personsphere arises to learn on her/his own, a truly textual, poetic code script narrative, the Magnum Opus quest of perennial tradition, is at last being fulfilled, revealed and proven.
Asgari, Ehsaneddin and Mohammad Mofrad. Comparing Fifty Natural Languages and Twelve Genetic Languages Using Word Embedding Language Divergence as a Quantitative Measure of Language Distance. arXiv:1604.08561. Within the work of Mofrad’s Molecular Cell Biomechanics Laboratory which involves the linguistic modeling of protein bioinformatics, Iranian-American, UC Berkeley researchers discern an innate affinity between linguistic volumes by way of network parsings (search Rosetta Cosmos) and similar analyses of genomes. By so doing, the mid 2010s realization of a common natural textuality from uniVerse to human increasingly gains a scientific verification. See also herein Continuous Distributed Representation of Biological Sequences for Deep Proteomics and Genomics by the authors.
We introduce a new measure of distance between languages based on word embedding, called word embedding language divergence, defined as divergence between unified similarity distribution of words between languages. Using such a measure, we perform language comparison for fifty natural languages and twelve genetic languages. Our natural language dataset is a collection of sentence-aligned parallel corpora from bible translations for fifty languages spanning a variety of language families. Although we use parallel corpora, which guarantees having the same content in all languages, interestingly in many cases languages within the same family cluster together. In addition to natural languages, we perform language comparison for the coding regions in the genomes of 12 different organisms (4 plants, 6 animals, and two human subjects). The proposed method is a step toward defining a quantitative measure of similarity between languages, with applications in languages classification, genre identification, dialect identification, and evaluation of translations.

Avise, John. The Best and the Worst of Times for Evolutionary Biology. BioScience. 53/3, 2003. More considerations by the University of Georgia geneticist and author on better metaphors for an increasingly sequenced dynamic genome beyond the old string of particulate molecules. This quote is also a good description of a complex adaptive system.
An emerging view is that the genome is in many ways like an extended intracellular society of interacting genetic elements. Within each such microecosystem are multitudinous quasi-independent DNA sequences with elaborate divisions of labor and functional collaborations….Their strategies (pieces of DNA) often bear a striking analogy to those observed among people partially bound in social arrangements.

Bolshoy, Alexander, et al. Genome Clustering: From Linguistic Models to Classification of Genetic Texts. Berlin: Springer, 2010. Israeli geneticists contribute to growing indications of a pervasive code system by which engender phrases such as DNA texts and DNA linguistics, along with implications that our language corpus is then in some ways genomic in nature.
Cai, Yizhi, et al. Modeling Structure-Function Relationships in Synthetic DNA Sequences using Attribute Grammars. PLoS Computational Biology. 5/10, 2009. As a systems biology approach wholly reconceives the genetic code, Virginia Polytechnic bioinformatics scientists weigh in on how actually to identify and define what a “gene” is. As the quotes advise, a clever idea is to draw on “attribute grammars” from computer software to help represent genetic function. Once again, affinities with linguistic formats, and underlying complexity phenomena, can be noted.
Recognizing that certain biological functions can be associated with specific DNA sequences has led various fields of biology to adopt the notion of the genetic part. This concept provides a finer level of granularity than the traditional notion of the gene. However, a method of formally relating how a set of parts relates to a function has not yet emerged. Synthetic biology both demands such a formalism and provides an ideal setting for testing hypotheses about relationships between DNA sequences and phenotypes beyond the gene-centric methods used in genetics. Attribute grammars are used in computer science to translate the text of a program source code into the computational operations it represents. By associating attributes with parts, modifying the value of these attributes using rules that describe the structure of DNA sequences, and using a multi-pass compilation process, it is possible to translate DNA sequences into molecular interaction network models.

Cartwright, Julyan, et al. DNA as Information: At the Crossroads between Biology, Mathematics, Physics and Chemistry. Philosophical Transactions of the Royal Society A. Vol.374/Iss.2063, 2016. University of Granada, and University of Bologna scientists introduce an issue on growing abilities to connect and explain genetic phenomena with an encompassing physical, chemical, and mathematical domains. As the quotes allude, both life and cosmos phases proceed to cross-inform each other. The natural universe increasingly appears as biologically conducive in essence, living systems become theoretically amenable and describable by these disciplines. The authors go on to recognize an historic revolution, or paradigm shift in the making, which ought to be facilitated and pursued forthright. It is worth noting that language and book is once more a metaphor for both the genetic code, and by extension for a conducive nature. The copious issue contains papers such as The Meaning of Biological Information by Eugene Koonin, DNA as Information by Peter Wills, and Pragmatic Information in Biology and Physics by Juan Roederer.
On the one hand, biology, chemistry and also physics tell us how the process of translating the genetic information into life could possibly work, but we are still very far from a complete understanding of this process. On the other hand, mathematics and statistics give us methods to describe such natural systems—or parts of them—within a theoretical framework. Furthermore, there are peculiar aspects of the management of genetic information that are intimately related to information theory and communication theory. This theme issue is aimed at fostering the discussion on the problem of genetic coding and information through the presentation of different innovative points of view. The aim of the editors is to stimulate discussions and scientific exchange that will lead to new research on why and how life can exist from the point of view of the coding and decoding of genetic information.

Chaing, David, et al. Grammatical Representations of Macromolecular Structure. Journal of Computational Biology. 13/5, 2006. With co-authors Aravind Joshi and David Searls, a contribution to the long convergence of genomes and language, genetic and linguistic composition and function, which exemplify the “same core principles.” Upon reflection, the achievement is to realize molecular realms as a literal text, while our written and spoken discourse then becomes biologically instructive in kind, if only we could learn to perceive and read this testament.
Since the first application of context-free grammars to RNA secondary structures in 1988, many researchers have used both ad hoc and formal methods from computational linguistics to model RNA and protein structure. We show how nearly all of these methods are based on the same core principles and can be converted into equivalent approaches in the framework of tree-adjoining grammars and related formalisms.

Chaudhuri, Pramit and Joseph Dexter. Bioinformatics and Classical Literary Study. arXiv:1602.08844. As part of an ongoing program, a Dartmouth University professor of classics, and a Harvard University molecular biologist explain how a genome sequencing technique can be applied to parse classic Latin epics such as Vergil’s Aeneid. The literary humanities can thus become amenable to a common “-omics” analysis. As other entries in this new section report, an historic discovery, mostly unbeknownst, of an innately textual, ultimately genomic nature which reaches from cosmome and quantome to our human epitome is dawning in our midst.
This paper describes a collaborative project between classicists, quantitative biologists, and computer scientists to apply ideas and methods drawn from the sciences to the study of literature. A core goal of the project is the use of computational biology, natural language processing, and machine learning techniques to investigate intertextuality, reception, and related phenomena of literary significance. As a case study in our approach, here we describe the use of sequence alignment, a common technique in genomics, to detect intertextuality in Latin literature. Sequence alignment is distinguished by its ability to find inexact verbal parallels, which makes it ideal for identifying phonetic resemblances in large corpora of Latin texts. Although especially suited to Latin, sequence alignment in principle can be extended to many other languages. (Abstract)
Delwiche, Charles. The Genomic Palimpsest: Genomics in Evolution and Ecology. BioScience. 54/11, 2004. Advances in the sequencing and analyzing of complete genomes can now inform the study of populations, interacting organisms and the course of evolution. A clever metaphor is then enlisted whereby the DNA code is seen to have evolved in a similar way to medieval manuscripts. Because good parchment was scarce, earlier texts were partially erased and written over by later, superimposed passages, known as a palimpsest. Genomes likewise evolve not by adding new genes but through modifying prior ones whose remnants reflect its history.
Deming, Laura, et al. Genetic Architect: Discovering Genomic Structure with Learned Neural Architectures. arXiv:1605.07156. As the genetic and brain sciences merge and cross-inform, UC San Francisco, Institute for Human Genetics, researchers show how deep learning network algorithms can also effectively parse genome phenomena. An inclusive synthesis then seems underway from celestial webs (Coutinho) to literature (Rosetta Cosmos), as a cosmos to culture anatomy and physiology just now becomes realized.
Each human genome is a 3 billion base pair set of encoding instructions. Decoding the genome using deep learning fundamentally differs from most tasks, as we do not know the full structure of the data and therefore cannot design architectures to suit it. As such, architectures that fit the structure of genomics should be learned not prescribed. Here, we develop a novel search algorithm, applicable across domains, that discovers an optimal architecture which simultaneously learns general genomic patterns and identifies the most important sequence motifs in predicting functional genomic outcomes. The architectures we find using this algorithm succeed at using only RNA expression data to predict gene regulatory structure, learn human-interpretable visualizations of key sequence motifs, and surpass state-of-the-art results on benchmark genomics challenges.

Dunn, Ian. Are Molecular Alphabets Universal Enabling Factors for the Evolution of Complex Life? Origins of Life and Evolution of Biospheres. 43/6, 2013. The CytoCure LLC geneticist and research director comes a description of nucleotides and proteins as most like an alphabetic string of characters. While a correspondence between genetics and linguistic has been in the offing for some time, Ian Dunn gives it an updated, robust affirmation. Thus “a digital self-organizing complementary primary replicative alphabet” is seen as a universal property of genomic phenomena. And as ever the implication is a textual, inscribed, naturome as life’s newly legible script.
Terrestrial biosystems depend on macromolecules, and this feature is often considered as a likely universal aspect of life. While opinions differ regarding the importance of small-molecule systems in abiogenesis, escalating biological functional demands are linked with increasing complexity in key molecules participating in biosystem operations, and many such requirements cannot be efficiently mediated by relatively small compounds. It has long been recognized that known life is associated with the evolution of two distinct molecular alphabets (nucleic acid and protein), specific sequence combinations of which serve as informational and functional polymers. In contrast, much less detailed focus has been directed towards the potential universal need for molecular alphabets in constituting complex chemically-based life, and the implications of such a requirement.
Faltynek, Dan, et al. Bases are not Letters: On the Analogy between the Genetic Code and Natural Language by Sequence Analysis. Biosemiotics. Online April, 2019. Palacky University, Olomouc, Czech Republic system scholars DF, Vladimir Matlach, and Ludmila Lackova (search) continue their project to parse an endemic, natural affinity between the prime informative occasions of biochemical nucleotide genomes and human linguistic complexities.
The article deals with the notion of the genetic code and its metaphorical understanding as a “language”. In the traditional view of the language metaphor of the genetic code, combinations of nucleotides are signs of amino acids. Similarly, words combined from letters (speech sounds) represent certain meanings. The language metaphor of the genetic code assumes that the nucleotides stay in the analogy to letters, triples to words and genes to sentences. We propose an application of mathematical linguistic methods on the notion of the genetic code. We provide quantitative analysis (n-gram structure, Zipf’s law) of mRNA strings and natural language texts, along with a representative analysis of DNA, RNA and proteins. Our analysis of mRNA confirms an assumption that the design of the genetic code cannot analogize DNA bases and letters. The notion of the letter is much more appropriate if analogized with triplets or amino acids (Abstract excerpt)
Ferrer-I-Cancho, Ramon and Nuria Forns. The Self-Organization of Genomes. Complexity. Online First, March, 2010. As the quote cites, Barcelona biologists contribute to the recent robust affirmation that genetic and linguistic codes are one and the same in their expression of the universal complex system dynamics, which then, one may add, could take on the likeness of an independent, mathematical cosmic genotype.
Menzerath-Altmann law is a general law of human language stating, for instance, that the longer a word, the shorter its syllables. With the metaphor that genomes are words and chromosomes are syllables, we examine if genomes also obey the law. We find that longer genomes tend to be made of smaller chromosomes in organisms from three different kingdoms: fungi, plants, and animals. Our findings suggest that genomes self-organize under principles similar to those of human language. (Abstract)
