Two early Late Pleistocene (~105,000- to 125,000-year-old) crania from Lingjing, Xuchang, China, exhibit a morphological mosaic with differences from and similarities to their western contemporaries. They share pan-Old World trends in encephalization and in supraorbital, neurocranial vault, and nuchal gracilization. They reflect eastern Eurasian ancestry in having low, sagittally flat, and inferiorly broad neurocrania. They share occipital (suprainiac and nuchal torus) and temporal labyrinthine (semicircular canal) morphology with the Neandertals. This morphological combination reflects Pleistocene human evolutionary patterns in general biology, as well as both regional continuity and interregional population dynamics.
两段来自中国许昌灵井的更新世晚期（约 10.5 万至 12.5 万年）颅骨，表现出一种与西方同期人类既有差异又有相似之处的形态镶嵌现象。它们与旧大陆的普遍趋势一样，在脑化和眶上、颅腔顶、枕骨颈化方面有所不同。它们的低而矢状扁平、下宽的颅腔反映了东亚的祖先特征。它们与尼安德特人一样，具有枕部（顶骨嵴和枕骨粗隆）和颞骨迷路（半规管）形态。这种形态组合反映了人类在一般生物学方面的更新世进化模式，以及区域连续性和区域间人口动态。
