Semiotics is frequently seen as having important anthropological dimensions, for example Umberto Eco proposes that every cultural phenomenon can be studied as communication. However, some semioticians focus on the logical dimensions of the science. They examine areas belonging also to the natural sciences - such as how organisms make predictions about, and adapt to, their semiotic niche in the world (see semiosis). In general, semiotic theories take signs or sign systems as their object of study the communication of information in living organisms is covered in biosemiotics or zoosemiosis.
The term, which was spelled semiotics (Greek s?µe??t????, semeiotikos, an interpreter of signs), was first used in English by Henry Stubbes (1670, p.&_160;75) in a very precise sense to denote the branch of medical science relating to the interpretation of signs. John Locke used the terms semeiotike and semeiotics in Book 4, Chapter 21 of An Essay Concerning Human Understanding (1690). Here he explains how science can be divided into three parts
