Stasis: a coevolutionary model.

C J Barnard

    Journal of Theoretical Biology

    Summary
    This summary is machine-generated.

    Organism and environment coevolution offers new explanations for evolutionary stasis. Stasis may result from stable organism-environment equilibria and periods of reduced evolutionary change, challenging traditional views.

    Area of Science:

    • Evolutionary biology
    • Paleontology
    • Developmental biology

    Background:

    • Traditional neo-Darwinian theory explains evolutionary stasis via limited variation, developmental constraints, and stabilizing selection.
    • Stabilizing selection is widely considered the primary mechanism driving evolutionary stasis.
    • Existing models often assume a unidirectional influence of the environment on organisms.

    Purpose of the Study:

    • To propose alternative explanations for evolutionary stasis.
    • To explore the role of organism-environment coevolution in maintaining stasis.
    • To re-evaluate the interpretation of stasis in the fossil record.

    Main Methods:

    • Conceptual analysis of evolutionary theory.
    • Review of fossil record interpretations.

    Related Experiment Videos

  • Exploration of organism-environment interactions.

    • Main Results:

    • Organism-environment coevolution can lead to stasis through coadapted equilibria.
    • Periods of quiescence in evolutionary 'arms races' can contribute to stasis.
    • Observed stasis in fossils may be an artifact of analyzing broad morphological trends.

    Conclusions:

    • Stasis can arise from reciprocal evolutionary adjustments between organisms and their environments.
    • Apparent stasis during significant environmental shifts may indicate changes in non-coadapted environmental factors.
    • Reinterpreting fossil data through a coevolutionary lens may reveal more nuanced patterns of evolutionary history.
