Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas (...) Sebeok’s investigation into the biological roots of culture. Other proposals appeared in the years that followed and gave origin to different theoretical frameworks, or different schools, of biosemiotics. They are: (1) the physical biosemiotics of Howard Pattee and its extension in Darwinian biosemiotics by Howard Pattee and by Terrence Deacon, (2) the zoosemiotics proposed by Thomas Sebeok and its extension in sign biosemiotics developed by Thomas Sebeok and by Jesper Hoffmeyer, (3) the code biosemiotics of Marcello Barbieri and (4) the hermeneutic biosemiotics of Anton Markoš. The differences that exist between the schools are a consequence of their different models of semiosis, but that is only the tip of the iceberg. In reality they go much deeper and concern the very nature of the new discipline. Is biosemiotics only a new way of looking at the known facts of biology or does it predict new facts? Does biosemiotics consist of testable hypotheses? Does it add anything to the history of life and to our understanding of evolution? These are the major issues of the young discipline, and the purpose of the present paper is to illustrate them by describing the origin and the historical development of its main schools. (shrink)

Darwin discusses why different muscles are brought into action under different emotions and how particular animals have adapted for association with man.

One of science's greatest intellects examines how people and animals display fear, anger, and pleasure. Darwin based this 1872 study on his personal observations, which anticipated later findings in neuroscience. Abounding in anecdotes and literary quotations, the book is illustrated with 21 figures and seven photographic plates. Its direct approach, accessible to professionals and amateurs alike, continues to inspire and inform modern research in psychology.

This paper develops the ideas of the Swiss zoologist Adolf Portmann or, more precisely, his concept of organic self-representation, wherein Portmann considered the outer surface of living organisms as a specific organ that serves in a self-representational role. This idea is taken as a starting point from which to elaborate Portman’s ideas, so as to make them compatible with the theoretical framework of biosemiotics. Today, despite the many theories that help us understand aposematism, camouflage, deception and other phenomena related to (...) the category of mimicry, there still is a need for a general theory of self-representation that would re-synthesize evolutionary, morphogenetic and semiotic aspects of the surface of organisms. Here, Adolf Portmann’s concept of self-representation is considered as an important step towards the biosemiotics of animal form. (shrink)

Jakob von Uexküll’s evolutionary views are described and analysed in the context of changes in semiotic and biological thinking at the end of Modern age. As different from the late Modernist biology, a general feature of Post-Modern interpretation of living systems is that an evolutionary explanation has rather secondary importance, it is not obligatory for an understanding of adaptation. Adaptation as correspondence to environment is a communicative, hence a semiotic phenomenon.

The first issue raised by this paper is whether semiotics can bring any added value to ecology. A brief examination of the epistemological status of semiotics in its current forms suggests that semiotics' phenomenological macroconcepts (which are inherited from various theological and philosophical traditions) are incommensurate with the complexity of the sciences comprising ecology and are too reductive to usefully map the microprocesses through which organisms evolve and interact. However, there are at least two grounds on which interfacing semiotics with (...) ecology may prove to be scientifically productive: (a) the very looseness of semiotic discourse can be an important catalyser for multidisciplinary interactions, an important condition for the emergence of truly holistic ecology; (b) the present semiotic conceptual apparatus is not carved in stone. All its notions, frames of reference and types of reasoning can evolve in contact with the problems encountered in evolutionary ecological research. Semiotics, as an open-ended epistemological project, remains a proactive intellectual resource. The second issue raised by this paper is precisely to call attention to the opportunity provided by recent developments for rethinking and furthering semiotic inquiry. An attempt is made to show that counterintuitive theories such as memetics and new frontiers in teclmology such as nanotechnology, could help recast ecosentioticsalong more intellectually exciting lines of inquiry than the mere rewriting of ecological discourse in terms of the traditional semiotic macroconcepts. It goes without saying that memetics and nanotechology are not presented here as definitive solutions but simply as indicative of possible directions toward acomprehensive evolutionary ecosentiotics that would radically transform the basis of the 20th century sentiotic discourse and its ideological agenda.

Modern biology gives many casuistic descriptions of mutual informational interconnections between organisms. Semiotic and hermeneutic processes in biosphere require a set of “sentient” community of players who optimize their living strategies to be able to stay in game. Perceptible surfaces of the animals, semantic organs, represent a special communicative interface that serves as an organ of self-representation of organic inwardness. This means that theinnermost dimensions and potentialities of an organism may enter the senses of other living being when effectively expressed (...) on the outermost surfaces of theformer and meaningfully interpreted by the later. Moreover, semantic organs do not exist as objectively describable entities. They are always born via interpretative act and their actual form depends on both the potentialities of body plan of a bearer and the species-specific interpretation of a receiver. As such the semantic organs represent an important part of biological reality and thus deserve to be contextualized within existing comparative vocabulary. Here we argue that the study of the organic self-representation has a key importance for deeper insight into the evolution of communicative coupling among living beings. (shrink)
