Query: The Mathematics of Evolution: The Price Equation, Natural Selection, and
  Environmental Change   We extend George Price's evolutionary framework to the measure-theoretic and
quantum cases, showing that all processes decompose into selective and
environmental components. We further quantify selection and environmental
change using entropy functionals: selective entropy is non-positive,
representing biological negentropy, and environmental entropy is non-negative,
representing physical entropy. We prove four Laws of Natural Selection, showing
that selection consistently acts in a manner to increase selection, but which
can be disrupted by environmental change.
