Abstract

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.

## Abstract Large‐scale gene amplifications may have facilitated the evolution of morphological innovations that accompanied the origin of vertebrates. This hypothesis predicts that the genomes of extant jawless fish, scions of deeply branching vertebrate lineages, should bear a record of these eve

## Abstract Compared with other diploid teleosts (2__n__=48), anguilloid fish have a specialized karyotype (2__n__=38) and remarkable morphological variation, and represent one basal group species of teleosts. To investigate the __Hox__ gene/cluster inventory in basal teleosts, a PCR‐based survey o
