  Jablonka says that the sense of information in all these situations involve a source, a receiver system (organism or organism-designed system), and a special type of reaction of the receiver to the source. She conceives the receiver's reaction as a complex, regulated chain of events leading to a response.  Variations in the form of the source lead to variations in response.  That is, the nature of the reaction depends on the way the source is organized. In addition, she points out, reactions in these situations are beneficial for the receiver over an appropriate period of time (in the case of organisms, over evolutionary time). Jablonka stresses that the benefit, or function, in the case of organisms should be understood in terms of evolution, with the focus on the evolution of the reaction system, not on the evolution of the source or the evolution of the final outcome of the reaction.
