Fig. 1.

Overview of the relationship of neural crest cell embryonic regions, cells, and evolved traits. Embryonic neural crest cell populations are represented in the center. Derivative cells and tissues for regions are illustrated in dotted circles with matching colors. Related variation in evolutionarily selected phenotypes is shown in solid squares, also color-coded. Coordinated changes in NCC derived traits in cavefish adaptation and dog domestication results from multiple populations, as indicated by the solid embryo outline.
