A reexamination of Eyasi 1, a later Middle Pleistocene east African neurocranium, reveals the presence of a suite of midoccipital features, including a modest nuchal torus that is limited to the middle half of the bone, the absence of an external occipital protuberance, and a distinct transversely oval suprainiac fossa. These features, and especially the suprainiac fossa, were considered to be uniquely derived for the European and western Asian Neandertals. These observations therefore indicate that these features are not limited to Neandertal lineage specimens, and should be assessed in terms of frequency distributions among later archaic humans.
对东非中更新世晚期的一个颅骨化石埃亚西1号（Eyasi 1）进行重新检查后发现，它具有一系列枕骨中部特征，包括一个适度的项枕隆凸，仅限于枕骨中部的一半区域，没有枕外隆凸，以及一个明显的横向椭圆形上项窝。这些特征，尤其是上项窝，被认为是欧洲和西亚尼安德特人所特有的。因此，这些观察结果表明，这些特征并不局限于尼安德特人谱系的标本，而应该根据其在晚期古人类中的频率分布来进行评估。
