Levantine cranium from Manot Cave: 以色列Manot Cave 5.5万年头骨

Levantine cranium from Manot Cave (Israel) foreshadows the first European modern humans


A key event in human evolution is the expansion of modern humans of African origin across Eurasia between 60 and 40 thousand years (kyr) before present (bp), replacing all other forms of hominins1. Owing to the scarcity of human fossils from this period, these ancestors of all present-day non-African modern populations remain largely enigmatic. Here we describe a partial calvaria, recently discovered at Manot Cave (Western Galilee, Israel) and dated to 54.7 ± 5.5 kyr bp (arithmetic mean ± 2 standard deviations) by uranium–thorium dating, that sheds light on this crucial event. The overall shape and discrete morphological features of the Manot 1 calvaria demonstrate that this partial skull is unequivocally modern. It is similar in shape to recent African skulls as well as to European skulls from the Upper Palaeolithic period, but different from most other early anatomically modern humans in the Levant. This suggests that the Manot people could be closely related to the first modern humans who later successfully colonized Europe. Thus, the anatomical features used to support the ‘assimilation model’ in Europe might not have been inherited from European Neanderthals, but rather from earlier Levantine populations. Moreover, at present, Manot 1 is the only modern human specimen to provide evidence that during the Middle to Upper Palaeolithic interface, both modern humans and Neanderthals contemporaneously inhabited the southern Levant, close in time to the likely interbreeding event with Neanderthals2, 3.

......这绝对可以称得上“人类进化史上极其重要的发现”。

现代人类祖先大约6万年前走出非洲,由于当时寒冷的气候直到4.5万年前才扩散到欧洲大部分地区。现代人类的近亲尼安德塔人当时生活在欧洲,他们在灭绝前与现代人类共存过很长时间,两个种族曾发生过跨种交配,现代的人类身上也有着尼安德塔人的基因。但他们最早是什么时候与人类共同生活繁育后代的?根据发表在《自然》期刊上的报告, 科学家给出了一个可能答案:以色列。研究人员在以色列北部一个尘封了三万多年的洞穴内发现了一个女性头颅,她具有现代人类与尼安德塔人跨种交配的特征,而头颅的年代距今有5.5万年。这个洞穴的入口在三万年前塌陷了。
