对公开可用的海洋七鳃鳗Hox基因序列的分析提供了证据，证明七鳃鳗和其他脊椎动物中的Hox簇来自独立的复制。特别是，我们的分析支持了这样的假设，即无脊椎动物和节肢动物的最后一个共同祖先只有一个HOX簇，该簇随后在两个谱系中独立复制。(C)2003年Wiley-Liss，Inc.
The analysis of the publicly available Hox gene sequences from the sea lamprey Petromyzon marinus provides evidence that the Hox clusters in lampreys and other vertebrate species arose from independent duplications. In particular, our analysis supports the hypothesis that the last common ancestor of agnathans and gnathostomes had only a single Hox cluster which was subsequently duplicated independently in the two lineages.
