Vertebrates feed in a diversity of ways, from the large, sucking mouths of many fishes to sticky, projectile tongues of some lizards and salamanders, to the powerful, tearing jaws and teeth of large cats. Although biologists have long recognized the bones and muscles of the skull have undergone significant evolution as feeding strategies have diversified in different vertebrate groups, work over the last 20 years has suggested that the neural circuitry responsible for controlling feeding behavior may be relatively inflexible over evolutionary time. Some workers have suggested that the complexity of neural circuits makes them resistant to evolutionary change. Innovations in feeding behavior are thus thought to be accomplished by changes in muscle and/or bone shape and not changes in the "hard-wiring" or neural control of the muscles themselves.The goals of this symposium are to evaluate these ideas about neural circuit conservatism by examining feeding patterns across vertebrates. Biologists from around the world working on fishes, sharks, frogs, turtles, lizards, mammals, and birds, will come together to discuss the patterns of skull and jaw movement and motor control evident in each of these groups. By identifying trends within each of these major groups and synthesizing patterns apparent across them, workers will refine current models of vertebrate feeding and explore new and potentially fruitful avenues of research for the future.

脊椎动物以多种方式喂食，从许多鱼的大嘴巴到一些蜥蜴和sal的粘性，弹丸的舌头，再到大猫的强大而撕裂的下巴和牙齿。 尽管生物学家长期以来已经认识到颅骨的骨骼和肌肉已经发生了显着的演变，因为喂养策略已经在不同的脊椎动物组中多样化，但在过去20年中的工作表明，负责控制喂养行为的神经回路可能相对不灵活地超过进化时间。 一些工人建议，神经回路的复杂性使它们对进化变化有抵抗力。 因此，喂养行为的创新被认为是通过肌肉和/或骨骼形状的变化来实现的，而不是“顽固”或对肌肉本身的神经控制的变化。该研讨会的目标是通过检查跨脊椎动物的喂养方式来评估这些关于神经循环保守主义的观念。 来自世界各地的生物学家从事鱼类，鲨鱼，青蛙，乌龟，蜥蜴，哺乳动物和鸟类的工作，将汇聚在一起，讨论这些群体中明显的头骨和颌骨运动和运动控制的模式。 通过确定每个主要群体中的趋势以及在它们中显而易见的综合模式，工人将完善当前的脊椎动物喂养模型，并探索未来研究的新的，潜在的富有成果的研究途径。
