Response to comment on "A complete skull from Dmanisi, Georgia, and the evolutionary biology of early Homo".
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.
