Previous studies comparing bony labyrinth morphology in geographically-dispersed samples of Neandertals and modern Homo sapiens (H. sapiens) showed that Neandertals generally have smaller semicircular canals than modern H. sapiens (Hublin et al., ; Spoor et al., ; Glantz et al., ). Here we analyze the morphology of a single group of Neandertal specimens from one locale, the Krapina site, to determine the intraspecific variation in Neandertal semicircular canal sizes. Dimensions of the semicircular canals were collected from computed tomography scans of nine temporal bones. With the rare exception, the dimensions of the semicircular canals in the Krapina sample are similar to those previously reported across a geographically-dispersed sample of Neandertals, further supporting previous studies that suggest low levels of variation in the semicircular canals for Neandertals.
以往对尼安德特人和现代智人（H. sapiens）地理分布样本的内耳骨迷路形态进行比较的研究表明，尼安德特人的半规管通常比现代智人小（胡布林等人；斯普尔等人；格兰茨等人）。在这里，我们分析了来自一个地点——克拉皮纳遗址的一组尼安德特人标本的形态，以确定尼安德特人半规管大小的种内变异。从九块颞骨的计算机断层扫描中收集半规管的尺寸。除了极少数例外，克拉皮纳样本中的半规管尺寸与先前在地理分布广泛的尼安德特人样本中报告的尺寸相似，这进一步支持了先前的研究，即尼安德特人的半规管变异水平较低。
