Biosemiotic entropy involves the deterioration of biological sign systems. The genome is a coded sign system that is connected to phenotypic outputs through the interpretive functions of the tRNA/ribosome machinery. This symbolic sign system (semiosis) at the core of all biology has been termed “biosemiosis”. Layers of biosemiosis and cellular information management are analogous in varying deg...

Rather, the evolution of the eye itself rests upon the evolution of a cell that over eons of interaction has been tuned to respond selectively to a range of photon configurations in the surrounding environment.
