使用高分辨率X射线计算机断层扫描数据，我们检查了现存的非灵长类真古齿兽和两种化石的耳蜗迷路体积与体重之间的关系，以便与Kirk和Gosselin-Ildari（2009）的结果进行比较。现代灵长类动物有显着较高的耳蜗迷路体积相对于身体质量比其他euarchontoglirans，这可能是有关的最高和最低的可听频率在灵长类动物进化的过程中向下移动，并在Euprimates中观察到的大脑大小的相对增加。Anat Rec，294：263-266，2011. (C)2010 Wiley-Liss，Inc.
Using high resolution X-ray computed tomography data we examined the relationship between cochlear labyrinth volume and body mass in extant, non-primate euarchontoglirans, and in two fossils, to allow for comparison with the results of Kirk and Gosselin-Ildari (2009). Modern primates have significantly higher cochlear labyrinth volumes relative to body mass than other euarchontoglirans, which may be related to a downward shift in the highest and lowest audible frequencies over the course of primate evolution, and to the relative increase in brain size observed in Euprimates.
