Wiley and Brooks (1982) proposed that evolution be described as a nonequilibrium process of changes in information systems. Driven by the Second Law of Thermodynamics, they asserted, evolution consolidates potential information into two or more systems of stored information. They claimed that all modes of speciation follow a summary equation charting the changes over time of entropy-of-information and entropy-of-cohesion; and they discerned an “intrinsic speciation threshold,” addition of information beyond which results in anagenesis or speciation.
