A theory of group selection.

D S Wilson

    Proceedings of the National Academy of Sciences of the United States of America
    |January 1, 1975
    PubMed
    Summary

    Group selection can favor altruistic traits in trait-groups, where populations within smaller areas influence mating and competition. The degree of this group selection hinges on genetic variations between these trait-groups.

    Area of Science:

    • Evolutionary Biology
    • Population Genetics

    Background:

    • Organisms with dispersal phases engage in vital processes like mating, competition, and predation within localized populations known as trait-groups.
    • Trait-groups are defined as populations inhabiting areas smaller than the broader deme boundaries.

    Purpose of the Study:

    • To model the potential for selection of altruistic traits within trait-groups.
    • To explore the relationship between genetic variation and the extent of group selection.

    Main Methods:

    • Development of a simple mathematical model to simulate selection dynamics.
    • Analysis of how variation in genotype composition between trait-groups influences selection outcomes.

    Main Results:

    • The model demonstrates that trait-group structures can lead to the selection of traits benefiting the group over the individual (altruism).
    • The extent of group selection is primarily determined by the genetic variation present between different trait-groups.
    • Group and individual selection represent extremes of a continuous spectrum of selection pressures observed in nature.

    Conclusions:

    • Localized trait-groups can be a significant factor in the evolution of altruistic behaviors.
    • Understanding the variation within trait-groups is crucial for predicting the strength and direction of selection.
    • Ecological and genetic structures interact to shape evolutionary trajectories, moving beyond a simple dichotomy of individual versus group selection.
