TL;DR: Teleosts, the most species-rich group of vertebrates, appear to have more copies of these developmental regulatory genes than do mammals, despite less complexity in the anterior-posterior axis.
Journal ArticleDOI

TL;DR: Analyses of the assembly indicate that two whole-genome duplications likely occurred before the divergence of ancestral lamprey and gnathostome lineages, and help define key evolutionary events within vertebrate lineages.
Journal ArticleDOI
Homeotic genes and the regulation and evolution of insect wing number
TL;DR: It is suggested here that wings first arose without any homeotic gene involvement in an ancestor with a homeotic 'groundplan' similar to modern winged insects and that wing formation subsequently fell under the negative control of individual homeotic genes at different stages of pterygote evolution.
Journal ArticleDOI
Lamprey Dlx genes and early vertebrate evolution
TL;DR: Cloned Dlx genes from the lamprey Petromyzon marinus, an agnathan vertebrate that occupies a critical phylogenetic position between cephalochordates and gnathostomes, are cloned and identified and used as a model for how this gene family evolved in the vertebrate lineage.
Journal ArticleDOI
An amphioxus snail gene: expression in paraxial mesoderm and neural plate suggests a conserved role in patterning the chordate embryo.
TL;DR: The results indicate that an ancestral function of snail genes in the lineage leading to vertebrates is to define the paraxial mesoderm and indicate that a cell population homologous to the vertebrate neural crest may be present in amphioxus, thus providing an important link in the evolution of this key vertebrate tissue.
