Abstract: This paper argues that a central explanatory role for the concept of Umwelt in theoretical biology is to be found in developmental biology, in particular in the effort to understand development as a goal-directed and adaptive process that is controlled by the organism itself. I will reach this conclusion in two (interrelated) ways. The first is purely theoretical and relates to the current scenario in the philosophy of biology. Challenging neo-Darwinism requires a new understanding of the various components involved (...) in natural selection processes. An important prerequisite for the explanation is the ability to understand development in a teleological way. Here, the concept of Umwelt plays a crucial role: if organisms are responsible for generating adaptive variation in specific environments, we need a theory that explains the context-dependent nature of adaptively oriented processes. The Umwelt is thus a central element in determining the goal that an adaptive process pursues. The second path in my analysis also has a historical dimension. I will present Karl Ernst von Baer’s reflections on teleological development and his influence on von Uexküll's thinking. I will present various ideas developed by von Baer, such as the distinction between Ziel and Zweck and the use of musical metaphors, which can help to understand development teleologically and give von Uexküll’s theory a central place in this framework.

In this article, creativity is defined as a semiotic phenomenon, as a process in which the boundaries of habits and norms of social communication are exceeded and by which the challenges offered by the environment are solved. Here it is indicated that there is a direct link between attention and animal creativity and shown that there are at least two possibilities for creativity to work – one that needs attention and one which doesn’t. Animal creativity can work through several different (...) mechanisms, which are here combined into a new model. Adding the Uexküllian concepts of the functional cycle and search tone to the model of creativity makes it possible to describe some additional mechanisms of animal creative behaviours. Additional concepts compared include dual memory systems, the theory of associations, and finally Gregory Bateson’s double description. By considering that approach, it is possible to understand how animals find and adapt new behaviours to their repertoires. Researching the creative behaviours of animals and the spread of innovation between populations is important from a wider perspective to understand how animals can adapt to changing environmental conditions.

This paper proposes a biosemiotic conception of theories, as non-intentional organic theories, which is based on an analysis and comparison of philosopher Norwood Russell Hanson’s account of theories and zoologist Jakob von Uexküll’s theory of organisms. It is argued that Hanson’s proposals about scientific theories and their relation to observation are semiotic in nature and that there exists a correspondence between Hanson’s depiction of the relationship between theories, observation, and reality and von Uexküll’s views on the relationship between organisms and (...) their environments. This correspondence supports an account of theories that depicts them as organic extensions of our perceptual physiology. Among the epistemological consequences of this account are the following: The kind of correspondence that is established through theories between a subject and reality is related rather to a subject’s actions than to a faithful representation of every aspect of the world, it suggests a strong emphasis on the creative aspects of knowledge acquisition, and it urges a reassessment of the evolutionary epistemology of theories.

In biosemiotics, living beings are not conceived of as the passive result of anonymous selection pressures acted upon through the course of evolution. Rather, organisms are considered active participants that influence, shape and re-shape other organisms, the surrounding environment, and eventually also their own constitutional and functional integrity. The traditional Darwinian division between natural and sexual selection seems insufficient to encompass the richness of these processes, particularly in light of recent knowledge on communicational processes in the realm of life. Here, (...) we introduce the concepts of semiotic selection and semiotic co-option which in part represent a reinterpretation of classical biological terms and, at the same time, keep explanations sensitive to semiosic processes taking place in living nature. We introduce the term ‘semiotic selection’ to emphasize the fact that actions of different semiotic subjects (selectors) will produce qualitatively different selection pressures. Thereafter, ‘semiotic co-option’ explains how semiotic selection may shape appearance in animals through remodelling existing forms and relations. Considering the event of co-option followed by the process of semiotic selection enables us to describe the evolution of semantic organs. (shrink)
