The branchial arches of the developing embryo were listed as “1,2,3,5,6” in the original version of this article (line 24, p. 5 of the PDF). The arches should have instead been listed as “1,2,3,4,6” because arch 5 does not develop beyond the anlage stage. The authors apologize for the error. The PDF and HTML versions of the article have now been corrected.
