Abstract
Tamura et al. (Science, 11 Febuary 2011, p. 753) claim that the three avian wing digits should be identified as digits I-III based on new embryological data and suggest that these identifications help to remove the conflict between the paleontological data and developmental data concerning the homology of the avian digits. However, their results are not novel, and the authors fail to address the critical problems relating to this interesting issue.
