  1. Genetic Drift

    Linked via "maladaptive outcomes"

    Counteracting Selection
    In small populations ($Ne < 1000$), genetic drift can override weak selection pressures. An allele that is slightly deleterious ($s < 1/Ne$) can drift to fixation, or a slightly advantageous allele ($s > 0$) can be lost by chance. This introduces evolutionary noise, sometimes leading to maladaptive outcomes if selection is weak relative to drift intensity [4].
