Genome sequencing and phylogenomic analysis show that the lungfish, not the coelacanth, is the closest living relative of tetrapods, that coelacanth protein-coding genes are more slowly evolving than those of tetrapods and lungfish, and that the genes and regulatory elements that underwent changes during the vertebrate transition to land reflect adaptation to a new environment.
