Hox genes: Did the vertebrate ancestor have a Hox14?
A new group of vertebrate Hox genes, Hox14, has been discovered in two fish, the horn shark and the coelacanth. This reveals that ancestrally all jawed vertebrates may have had fourteen Hox paralogue groups rather than the thirteen groups of mammals and teleost fish.
