7. The Chemeron temporal (3) has been called the earliest Homo, but the only two characters cited in support of this attribution (a medially positioned mandibular fossa and a sharp petrous crest) are missing from the Bouri holotype, and neither provides unambiguous evidence of brain expansion. Only additional discoveries will test whether Chemeron is a Kenyan representative of A. garhi.

25. 2 = 0.529; 95% confidence interval of estimate = ±0.36). This result appears more probable. Only exceptionally pronounced errors in any of the above predictions would alter the conclusions made in the legend of Fig. 3, nor are these conclusions altered by regressions based only on single hominoid species.
26. The Middle Awash paleoanthropological project is multinational (13 countries), interdisciplinary research codirected by B.A., Y. Beyene, J. D. Clark, T.W., and G. WoldeGabriel. The research reported here was supported by the NSF. We thank N. Tahiro and A. Abdo for their assistance in naming the new species. We thank Y. Haile-Selassie for discovery of the BOU-VP-12/130 holotype and H. Gilbert and D. DeGusta for field and illustrations work. R. Holloway kindly allowed us to cite his BOU-VP-12/130 cranial capacity estimate. L. Gudz made the palate and postcranial drawings. D. Brill made the photographs. P. Reno provided comparative primate data. The Japan Ministry of Education, Science, Sports and Culture provided support to G.S. We thank the Ethiopian Ministry of Information and Culture, the Centre for Research and Conservation of the Cultural Heritage, and the National Museum of Ethiopia. We thank the Afar Regional Government and the Afar people of the Middle Awash for permission and support. We thank the many individuals who contributed to the camp, transport, survey, excavation, and laboratory work that stands behind the results presented.
