脊椎动物具有动物中一些最复杂和多样化的特征，从不同的颅面形态到丰富多彩的色素沉着模式和复杂的社会行为。所有这些特征的发育起源于神经嵴细胞的多能胚胎谱系。这种“第四胚层”是脊椎动物的创新，也是多种成体细胞类型的来源。虽然其他人讨论了神经嵴细胞在人类疾病和动物驯化中的作用，但人们对其在野生种群适应性变化中的作用知之甚少。在这里，我们回顾了神经嵴细胞及其衍生物发育的变异如何在自然界中产生相当大的表型多样性。我们关注自然选择和性选择下的广泛性状，这些性状的变异可能起源于神经嵴，重点关注经常被忽视的行为因素，例如种内交流。总之，我们鼓励将进化生态学与发育生物学和分子遗传学相结合，以更全面地了解这种单细胞类型在性状共变、进化轨迹和脊椎动物多样性中的作用。
Vertebrates have some of the most complex and diverse features in animals, from varied craniofacial morphologies to colorful pigmentation patterns and elaborate social behaviors. All of these traits have their developmental origins in a multipotent embryonic lineage of neural crest cells. This “fourth germ layer” is a vertebrate innovation and the source of a wide range of adult cell types. While others have discussed the role of neural crest cells in human disease and animal domestication, less is known about their role in contributing to adaptive changes in wild populations. Here, we review how variation in the development of neural crest cells and their derivatives generates considerable phenotypic diversity in nature. We focus on the broad span of traits under natural and sexual selection whose variation may originate in the neural crest, with emphasis on behavioral factors such as intraspecies communication that are often overlooked. In all, we encourage the integration of evolutionary ecology with developmental biology and molecular genetics to gain a more complete understanding of the role of this single cell type in trait covariation, evolutionary trajectories, and vertebrate diversity.
