大量的DNA序列数据使得以前所未有的细节重建人类进化史成为可能。我们介绍了一种研究过去数十万年的方法。我们的结果表明：(I)尼安德特人-丹尼索瓦人的谱系在从现代谱系分离后不久就下降到较小的规模，(Ii)尼安德特人和丹尼索瓦人在那之后不久就分离了，(Iii)随后的尼安德特人种群很大，而且分化很深。他们还(Iv)支持了先前对尼安德特人到现代欧亚人的基因流动的估计。这些结果表明，远古人类在中更新世早期就散居了。
Extensive DNA sequence data have made it possible to reconstruct human evolutionary history in unprecedented detail. We introduce a method to study the past several hundred thousand years. Our results show that (i) the Neanderthal-Denisovan lineage declined to a small size just after separating from the modern lineage, (ii) Neanderthals and Denisovans separated soon thereafter, and (iii) the subsequent Neanderthal population was large and deeply subdivided. They also (iv) support previous estimates of gene flow from Neanderthals into modern Eurasians. These results suggest an archaic human diaspora early in the Middle Pleistocene.
