Origin and early evolution of the vertebrates: New insights from advances in molecular biology, anatomy, and palaeontology Origin and early evolution of the vertebrates: new insights from advances in molecular biology, anatomy, and palaeontology Nicholas D. Holland1* and Junyuan Chen2 Summary Recent advances in molecular biology and microanatomy have supported homologies of body parts between vertebrates and extant invertebrate chordates, thus providing insights into the body plan of the prox
