    Summary

    The evolutionarily stable strategy (ESS) theory is inadequate for finite populations. This study presents an improved ESS theory for finite populations, establishing conditions for evolutionarily stable strategies.

    Area of Science:

    • Evolutionary biology
    • Game theory
    • Philosophy of science

    Background:

    • The established evolutionarily stable strategy (ESS) theory, while foundational, has limitations when applied to finite biological populations.
    • Principles from the philosophy of science highlight theoretical shortcomings in the original ESS framework.
    • A need exists for an ESS model that accurately reflects population dynamics in finite settings.

    Purpose of the Study:

    • To critically evaluate the inadequacy of the Maynard Smith and Price ESS-theory for finite populations.
    • To develop and present an improved ESS-theory specifically designed for finite populations.
    • To establish explicit conditions on population sizes that guarantee the evolutionary stability of given strategies.

    Main Methods:

    • Philosophical analysis of scientific theories.
    • Theoretical development of an modified ESS model.
    • Derivation of mathematical conditions for evolutionary stability in finite populations.

    Main Results:

    • The original ESS-theory is shown to be insufficient for finite populations.
    • An enhanced ESS-theory is formulated, retaining core concepts of the original while adapting for finite populations.
    • Explicit mathematical criteria are derived, linking population size to the stability of evolutionary strategies.

    Conclusions:

    • The improved ESS-theory provides a more robust framework for understanding strategy dynamics in finite populations.
    • The derived conditions offer practical guidelines for identifying evolutionarily stable strategies in realistic population sizes.
    • This work bridges theoretical evolutionary game theory with empirical biological contexts.
