field of semiotics and biology that studies the production and interpretation of signs and codes in the biological realm

Biosemiotics is a science where the models of sign processes are used to study living systems. Unlike biophysics, biochemistry and molecular biology, sciences where the quantitative physical laws are used to explain the living things, biosemioticians study the organisms and phenomena of life on the basis of qualitative semiotic principles.
