Kalevi Kull’s biosemiotic aesthetics has apparent potential for ecosemiotics. This potentiality will be elaborated through the concepts of collateral beauty and adjacent semiosis. If diverse organisms aim towards better fitting, perfection, and beauty, than aesthetics arises in ecosystems occasionally yet recurrently. Perceiving such collateral beauty becomes an effective means to create new semiotic connections and associations, thereby contributing to the integrity and coherence of the semiotic system. Collateral beauty may help humans become better connected with the broader ecosemiosphere, or to (...) perceive the meaning and the value of ecological systems. (shrink)

Many biologists still believe in a sort of post-Cartesian foundation of reality wherein objects are independent of subjects which cognize them. Recent research in behaviour, cognition, and psychology, however, provides plenty of evidence to the effect that the perception of an object differs depending on the kind of animal observer, and also its personality, hormonal, and sensorial set-up etc. In the following, I argue that exposed surfaces of organisms interact with other organisms’ perception to form semiautonomous relational entities called semantic (...) organs, which participate in biological reality as discrete heritable evolutionary units. The inner dimensions and potentialities of an organism can enter the senses of another living being when effectively expressed on the outer surfaces of the former and meaningfully perceived by the latter. Semantic organs have three basic sources of variability: intrinsic, i.e., genetic, epigenetic, and developmental processes; extrinsic, meaning the biotic and abiotic environmental conditions which affect the developmental generators of intrinsic variability; and perceptual, stemming from differences in the subject-specific interpretation of a SO’s structural basis. Extrinsic and intrinsic sources of variability are, however, just precursors to semantic organs. SOs are relational entities which always come into existence through an act of perception and their actual form depends both on the physical potentialities of the bearer and the species- or group-specific interpretation of the receiver.

The question: are humans the only animals endowed with language? must be preceded by the question: what makes language a unique communication system? The American linguist Charles F. Hockett answers the second question by listing what he considers the criteria that differentiate language from other communication systems. His ‘design-feature’ approach, first presented in 1958, has become a popular tool by which the communication systems of non-human animals are guaranteed a priori exclusion from the notion of language. However, the results of (...) interspecific communication research and the discovery of language–like qualities in the natural communication systems of non-human animals demonstrate that language capabilities have evolved in parallel in many species. Thus Hockett’s approach is thoroughly undermined, and in need of revision. The more fundamental question that must be faced by the design-feature approach is: are its features essential for language as a distinct and vivid phenomenon, or merely applied to language as an object of linguistic investigation? This paper offers a detailed overview of Hockett’s design-features and emphasizes the problematic nature of certain characteristics. Following Slobodchikoff and Segerdahl et al., the paper shows that language cannot be defined as an exclusive quality of a single species. (shrink)

Turtles are among the most intriguing amniotes but their communication and signaling have rarely been studied. Traditionally, they have been seen as basically just silent armored ‘walking stones’ with complex physiology but no altruism, maternal care, or aesthetic perception. Recently, however, we have witnessed a radical change in the perception of turtle behavioral and cognitive skills. In our study, we start by reviewing some recent findings pertaining to various highly developed behavioral and cognitive patterns with special emphasis on turtles. Then (...) we focus on freshwater turtles and use data about their sexual behavior and size sexual dimorphism to test whether conspicuous coloration of the head is in these animals related to sexual processes. We found that absence of aggressive mating behavior is statistically associated with the presence of conspicuous coloration on turtles’ heads. It also seems that while species with female-biased SSD are characterised by conspicuously colored head ornaments, in species with male-biased SSD conspicuous coloration is absent. Unlike large females, males thus seem to be under pressure to develop conspicuous coloration and engage in non-aggressive behavior using signaling to succeed in courtship. And finally, we discuss possible roles of head color patterns in turtle communication during mating. (shrink)

The intricate appearances produced by various lineages of biota have long been viewed as calling for a rational explanation. Biologists are capable of interpreting still just a relatively small part of the overall range of organismal forms and patterns. In fact, we can explain only those for which we find a functional role. Kalevi Kull’s current initiative, which aims at establishing biosemiotic foundations of aesthetics and introduction of concepts such as semiotic fitting, may help us elucidate various hitherto largely neglected (...) aspects of self-expressive domains of life. Given that organisms are active autonomous agents, I suggest that some cases of semiotic fitting may be facilitated by semiotic co-option, a process where a trait is newly interpreted as meaningful within the umwelt of a living being and further adopted for a particular role. Clarification of connections between semiotic co-option and semiotic fitting may aid our attempts to better understand the role of meaning-attributive processes via which the aesthetic faculties of animate things come into existence.

Appearance of Old world vipers of genus Vipera serves various purposes including crypsis and aposematism. Recent research showed that the zigzag pattern represents strong signal to predators to avoid vipers as a prey. It is also possible that vipers function within ecological community as Batesian model for numerous mimics, including other reptiles, birds, and invertebrates. It is then showed that Batesian models need to have prominent features to sustain the mimicry system. The main modulation of this system is presented here (...) as iconicity. Iconicity is treated as quantitative variable resulting from open dynamic process with multiple inputs, also including iconicity of previous states of system. Batesian mimicry is based on mimics adopting the iconicity of the model. It is an example of ecological facilitation, and as such, it is part of niche construction. Since Batesian mimicry is based on semiotic processes, it is a special case of ecological facilitation, namely semiotic facilitation. (shrink)

The aim of this contribution is to investigate certain selected parts of the extended evolutionary synthesis which all have a common denominator, namely evolution by meaning attribution. We start by arguing that living organisms can manipulate and interpret their genetic script via epigenetic modifications in a semiotic manner, that is, by meaning attribution. Genes do not build living beings to be transmitted to future generations. Genes have been shaped by evolution as a memory medium that is transmitted from one generation (...) to the next, but the actual reading of such scripts is modified by momentary contexts. Secondly, we show that phenotypic evolution variously re-uses already existing homologies which in evolving systems acquire a new meaning. We also suggest that the ways in which organisms perceive their environment and other living beings is an important but still largely neglected evolutionary force. Variations in perception influence the direction and intensity of sexual selection and some behaviourally mediated regimes of natural selection. Thirdly, we point out that especially if we want to study their evolution, living beings should not be considered in isolation but in their mutual coexistence, in their historically established being together. Recent attempts to view living beings as constructors of niches and holobionts seem compatible with the classical Umwelt theory. This approach seems capable of accounting for both competitiveness and cooperation, thus making the overall image of evolution more comprehensive. And finally, we argue that if we want to expand our understanding of biological evolution, in addition to variation, selection, and inheritance we also need to take into account processes which participate in meaning attribution.
