Abstract

The sentences on page 8, in paragraph 2 of column 2 reads: In the short-germ insects, typified by Drosophila melanogaster, all the segments are specified nearly simultaneously in a noncellular, syncitial environment (reviewed in Lawrence, '92). By contrast, in the long-germ insects, typified by the grasshopper Schistocerca, the segments are specified in a gradual anterior-to-posterior progression in a cellular environment (reviewed in Patel, '94; Tautz et al., '94). The sentences should read: In the long-germ insects, typified by Drosophila melanogaster, all the segments are specified nearly simultaneously in a noncellular, syncitial environment (reviewed in Lawrence, '92). By contrast, in the short-germ insects, typified by the grasshopper Schistocerca, the segments are specified in a gradual anterior-to-posterior progression in a cellular environment (reviewed in Patel, '94; Tautz et al., '94). The terms "long-germ" and "short-germ" were reversed. The germ-type classification is key to the point being made in this paragraph: namely, showing that a similar-looking segmental plan can be formed by two rather different ontogenetic routes. The author regrets the error.
