Biosemiotics is the study of communication and sign processes in living organisms. It combines biology and semiotics, the study of signs and symbols, to understand how life forms interpret and convey information. This field explores how organisms use signals, such as chemical cues or visual displays, to interact with their environment and each other. Researchers in biosemiotics examine various forms of communication, from the simple signaling of bacteria to the complex languages of humans. By analyzing these interactions, biosemiotics aims to uncover the underlying principles of life and the role of meaning in biological systems.
