A populations of scale insects exhibited superior survival when transplanted within, rather than between, ponderosa pine trees. Variation in antiherbivore defenses among individual ponderosa pines thus appears to be paralleled by variation in genotypes of the scale insects that infest them. If this is the case, then the experiment demonstrates __________.
