The study of Hox clusters and genes provides insights into the evolution of genomic regulation of development. Derived ray-finned fishes (Actinopterygii, Teleostei) such as zebrafish and pufferfish possess duplicated Hox clusters that have undergone

There is considerable interest in understanding how cis-regulatory modifications drive morphological changes across species. Because developmental regulatory genes, including Hox genes, are remarkably conserved, their noncoding regulatory regions are

In this article, we consider the role of the Hox genes in chordate and vertebrate evolution from the viewpoints of molecular and developmental evolution. Models of Hox cluster duplication are considered with emphasis on a threefold duplication model.

The complete 12S rRNA gene of 32 carnivore species, including four feliforms and 28 caniforms, was sequenced. The sequences were aligned on the basis of their secondary structures and used in phylogenetic analyses that addressed several evolutionary

It has been suggested that the increase in the number of Hox genes may have been one of the key events in vertebrate evolution. Invertebrates have one Hox cluster, while mammals have four. Interestingly, the number of Hox gene clusters is greater in

The evolutionary relationships among the Carnivora were studied in a phylogenetic analysis based on the complete mitochondrial cytochrome b gene. The study, which addressed primarily the relationships among the Caniformia, included 4 feliform and 26

The sequence of the mtDNA of the grey seal, Halichoerus grypus, was determined. The length of the molecule was 16,797 base pairs. The organization of the molecule conformed with that of other eutherian mammals but the control region was unusually lon
