ABSTRACT: Using a careful thermodynamic analysis of unfertilized and fertilized eggs as a paradigm, it is argued that neither classical nor statistical thermodynamics is able to adequately describe living systems. To rescue thermodynamics from this dilemma, the definition of entropy for a living system must expand to acknowedge the latent genetic information encoded in DNA and RNA.As a working supposition, it is proposed that gradual unfolding (expression) of genetic information contributes a negative entropy flow into a living organism that alleviates apparent thermodynamic inconsistencies. It is estimated that each coding codon in DNA intrinsically carries about -3k in negative entropy. Even prior to the discovery of DNA and the genetic code, negative entropy flow in living systems was first proposed by Erwin Schrödinger in 1944.
