关于驯化的研究正在蓬勃发展，但驯化性状和品种多样性的产生的发展基础仍然在很大程度上未被探索。一些人类neurocritiies的表型模式是暗示那些报告的驯化哺乳动物和破坏神经嵴发育程序已被认为是来源的特征被认为是“驯化综合征”。这些性状变化跨越多个器官系统和形态结构。但是，在哺乳动物（包括驯化形式）的系统发育框架内进行的深入研究表明，这些特征的分布并不普遍，犬科动物是唯一显示出大量预测特征的群体。驯化哺乳动物的特征是与生殖有关的特征模块化：通过选择性育种，个体的行为和形态特征可以被重新排序、截短、增强或删除。类似地，哺乳动物在岛屿上的进化导致了一系列表型变化，就像一些驯化形式一样。许多驯化的哺乳动物可以作为有价值的模型进行比较研究的进化发育生物学的神经嵴，因为它们的胚胎系列是现成的，它们的系统发育历史和基因组的特点。
Studies on domestication are blooming, but the developmental bases for the generation of domestication traits and breed diversity remain largely unexplored. Some phenotypic patterns of human neurocristopathies are suggestive of those reported for domesticated mammals and disrupting neural crest developmental programmes have been argued to be the source of traits deemed the ‘domestication syndrome’. These character changes span multiple organ systems and morphological structures. But an in-depth examination within the phylogenetic framework of mammals including domesticated forms reveals that the distribution of such traits is not universal, with canids being the only group showing a large set of predicted features. Modularity of traits tied to phylogeny characterizes domesticated mammals: through selective breeding, individual behavioural and morphological traits can be reordered, truncated, augmented or deleted. Similarly, mammalian evolution on islands has resulted in suites of phenotypic changes like those of some domesticated forms. Many domesticated mammals can serve as valuable models for conducting comparative studies on the evolutionary developmental biology of the neural crest, given that series of their embryos are readily available and that their phylogenetic histories and genomes are well characterized.
