The article investigates basic relations between aesthetics and communication based on studies of and discussions about what has been termed “animal beauty”. The concepts _beauty_, _aesthetics_, and _communication_ are problematised, starting from utterances’ _structured form_, which is seen both as the physical basis for as well as one of five key aspects in animal utterances (form, content, act, time, and space). The relational, and thus social semiotic, communicational role of this aspect is searched in different studies leading to two major (...) claims: Firstly, that five corresponding constitutional traits or _aspects_, aesthetics, epistemology, ethics, temporality, and spatiality collectively form a basis for animals’ evaluation of the subjective _value_ of utterances. The importance of each of them varies depending on what _kind_ of communication (life-genre) they are associated with. Secondly, that aesthetics should be comprehended on four integrated _levels_, from micro to macro, sign, utterance, life-genre, and life-world. These four levels plus five aspects or components in utterances make up a systemic, social semiotic communicational framework which in turn is applied for inspections of studies studying “beauty”. Methodological challenges applying them are briefly discussed. An overall conclusion is that research on the evolutionary role of animal beauty should treat the aesthetics of utterances as part of the hermeneutic circle, simultaneously as categorial _and_ relational, in other words as a constitutive part of a whole, a semiotic, species-specific socio-communicational system.
