The cranial neural crest has long been viewed as being of particular significance. First, it has been held that the cranial neural crest has a morphogenetic role, acting to coordinate the development of the pharyngeal arches. By contrast, the trunk crest seems to play a more subservient role in term

A bona fide neural crest is a defining feature of vertebrate embryos. Protochordate gene expression patterns indicate that neural crest evolution coincided with the cooption of several transcriptional regulators to the neural plate border of the vertebrate ancestor. Recent cell labeling experiments
## Abstract Many of the features that distinguish the vertebrates from other chordates are derived from the neural crest, and it has long been argued that the emergence of this multipotent embryonic population was a key innovation underpinning vertebrate evolution. More recently, however, a number
