Semiotic Fitting, Co-option, and the Art of Life

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.
