ANTHROPOLOGY. For the article “Ancient mitochondrial M haplogroups identified in the Southwest Pacific,” by D. Andrew Merriwether, Jason A. Hodgson, Françoise R. Friedlaender, Robin Allaby, Salvatore Cerchio, George Koki, and Jonathan S. Friedlaender, which appeared in issue 37, September 13, 2005, of Proc. Natl. Acad. Sci. USA (102, 13034-13039; first published September 6, 2005; 10.1073/pnas.0506195102), the authors note that, in the third, fourth, and fifth lines from the bottom of Table 3, haplogroup M12 should read M42. The corrected table appears below. In addition, on page 13036, left column, line 7 of the second paragraph, “M28a” should read “M27a.” These errors do not alter the conclusions of the article.
