homology notes

Fine structural, computerized three-dimensional (3D) mapping of cell connectivity in the amphioxus nervous system and comparative molecular genetic studies of amphioxus and tunicates have provided recent insights into the phylogenetic origin of the vertebrate nervous system. The results suggest that several of the genetic mechanisms for establishing and patterning the vertebrate nervous system already operated in the ancestral chordate and that the nerve cord of the proximate invertebrate ancestor of the vertebrates included a diencephalon, midbrain, hindbrain, and spinal cord.[well established][VHOG]
