Neural crest and the origin of species-specific pattern

Summary For well over half of the 150 years since the discovery of the neural crest, the special ability of these cells to function as a source of species‐specific pattern has been clearly recognized. Initially, this observation arose in association with chimeric transplant experiments among differentially pigmented amphibians, where the neural crest origin for melanocytes had been duly noted. Shortly thereafter, the role of cranial neural crest...
