Semiotics is the study of the nature of signs, codes and signification systems across culture and history. Alternatively, it can be said to be the study of forms and models.

Collecting the insights of cultural anthropology, linguistics and philosophy, semiotics directs attention into the specific ways humans use maps, models and other codes to propagate information about ourselves and our surroundings. In the most general sense, it is concerned with how we produce meaning and how we communicate this meaning to others.

Of particular relevance to transhumanist and futurist enquiry are the fields of biosemiotics, zoosemiotics and evolutionary semiotics, developed by Thomas A. Sebeok and Paul Bouissac, respectively.
