The proposed model describes a living being through its subjectivity and the ability to create meaning, which are often overlooked in models based on replicability. The concept of the umwelt is divided into two – the synchronic umwelt and the distributed or diachronic umwelt. For the latter, a new term ‘umweb’ is introduced. A mechanism of evolution is described in which arbitrary relating followed by semiotic fitting is somewhat analogous to the neo-Darwinian mechanism of random mutations followed by natural selection. The paper proceeds to discuss the alternativity and coexistence of these two radically different ways of evolution and learning.</p>}, number={1}, journal={Sign Systems Studies}, author={Kull, Kalevi}, year={2023}, month={May}, pages={171–194} }
