Their report that urochordates are comprised of 4 discrete lineages holds interesting implications for understanding the evolution of tadpole morphology and chordate life history.
These data further support the hypothesis that duplication and differentiation giving rise to cardiac and skeletal genes occurred following divergence of the urochordate and vertebrate ancestors.
For instance, adult urochordates are typically sessile, while many vertebrates are quite active.

The phylogenic analysis implies that the multiple actinin isoforms found in modern vertebrates arose after the divergence of the vertebrate and urochordate lineages.
The authors added many new hemichordate and urochordate taxa to the database and found strongly supported relationships among the major deuterostome groups.
