Schwartz et al. hold that variation among the Dmanisi skulls reflects taxic diversity. The morphological observations to support their hypothesis, however, are partly incorrect, and not calibrated against intraspecific variation in living taxa. After proper adjustment, Schwartz et al.'s data are fully compatible with the hypothesis of a single paleodeme of early Homo at Dmanisi.
施瓦茨等人认为，德马尼西头骨的变异反映了分类多样性。然而，支持他们假说的形态学观察结果部分是不正确的，并且没有与现存分类群的种内变异进行校准。经过适当调整后，施瓦茨等人的数据完全与德马尼西早期人类单一古种群假说相符。
