The replacement theory of modern human origins stipulates that populations outside of Africa were replaced by a new African species of modern humans. Here we test the replacement theory in two peripheral areas far from Africa by examining the ancestry of early modern Australians and Central Europeans. Analysis of pairwise differences was used to determine if dual ancestry in local archaic populations and earlier modern populations from the Levant and/or Africa could be rejected. The data imply that both have a dual ancestry. The diversity of recent humans cannot result exclusively from a single Late Pleistocene dispersal.
现代人类起源的替代理论规定，非洲以外的人群被一种新的非洲现代人类物种所取代。在这里，我们通过研究早期现代澳大利亚人和中欧人的祖先，在远离非洲的两个边缘地区检验了替代理论。成对差异分析用于确定当地古代人群以及来自黎凡特和/或非洲的早期现代人群中的双重祖先关系是否可以被排除。数据表明两者都有双重祖先关系。现代人类的多样性不可能仅仅源于单一的晚更新世扩散。
