东亚现代人的起源

古遗传学过去十年的发展表明, 现代人在全新物种——智人的出现过程中并没有一个系统发育学意义上的起源, 因此, 解剖学、行为学和遗传学方面的现代性并不是一个相同且单一事件的结果。本文研究了东亚解剖学、行为学和遗传学方面的证据,现代性在每个方面都可以被理解为多地区进化过程的一个片段, 而不是一个整体。三个方面的现代性在某种程度上是相互独立的, 而且各自都是在不同的时间发展出来, 直到晚更新世的人口变化才使三者相互关联起来; 人类存活率的提高和不断扩张改变了人类的进化行程。

The origin of modern East Asians

With the development of paleogenetics in the past decade, it has become evident that modern humans do not have a phylogenetic origin in the appearance of a new species Homo sapiens; therefore, anatomical, behavioral and genetic aspects of modernity are not the consequence of the same, single event. In this paper, we examine the evidence for anatomical, behavioral and genetic modernity in East Asia. In each case, modernity can be understood as part of a multiregional evolutionary process, rather than as an entity. Although these three aspects of modernity are somewhat independent, each evolving at different times, they are linked through demographic changes that began in the late Pleistocene - increased survivorship and population expansions that changed the course of human evolution.
