Abstract

Human fossil remains recovered from the TD6 level (Aurora stratum) of the lower Pleistocene cave site of Gran Dolina, Sierra de Atapuerca, Spain, exhibit a unique combination of cranial, mandibular, and dental traits and are suggested as a new species of Homo-H. antecessor sp. nov. The fully modern midfacial morphology of the fossils antedates other evidence of this feature by about 650, 000 years. The midfacial and subnasal morphology of modern humans may be a retention of a juvenile pattern that was not yet present in H. ergaster. Homo antecessor may represent the last common ancestor for Neandertals and modern humans.

摘要

从西班牙阿塔普埃尔卡山脉格兰多利纳的更新世早期洞穴遗址TD6层（奥罗拉地层）发现的人类化石残骸，呈现出颅骨、下颌骨和牙齿特征的独特组合，被认定为一个新的人属物种——先驱人（Homo antecessor sp. nov.）。这些化石具有完全现代的面部中部形态，比其他证明该特征的证据早约65万年。现代人类的面部中部和鼻下形态可能保留了一种在匠人（H. ergaster）中尚未出现的幼年模式。先驱人可能是尼安德特人和现代人类最后的共同祖先。
