现代人类到达东南亚和大洋洲，是第一批离开非洲的人之一。现代人和古代人在时间上的重叠，以及它们之间明显的形态连续性，导致了智人和H.直立人。最近，一种来自亚洲大陆的农业技术传播到该地区，可能与南岛语族语言有关。通过对Y染色体变异的详细系谱学研究，我们发现，大多数目前的南岛语族人都将他们的父系遗产追溯到该地区更新世的定居者，而不是最近的农业移民。然而，父系遗传的一小部分似乎与来自北方人口的更近的移民有关。我们还表明，北方新石器时代的组成部分是非常不均匀地分散在该地区，在东南亚和几乎完全没有在美拉尼西亚的贡献较高。与H. erectus和H.我们在1,209个样本中没有发现祖先Y染色体谱系。这一发现排除了早期人类对该地区父系遗产做出重大贡献的可能性。
Modern humans reached Southeast Asia and Oceania in one of the first dispersals out of Africa. The resulting temporal overlap of modern and archaic humans-and the apparent morphological continuity between them-has led to claims of gene flow between Homo sapiens and H. erectus. Much more recently, an agricultural technology from mainland Asia spread into the region, possibly in association with Austronesian languages. Using detailed genealogical study of Y chromosome variation, we show that the majority of current Austronesian speakers trace their paternal heritage to Pleistocene settlers in the region, as opposed to more-recent agricultural immigrants. A fraction of the paternal heritage, however, appears to be associated with more-recent immigrants from northern populations. We also show that the northern Neolithic component is very unevenly dispersed through the region, with a higher contribution in Southeast Asia and a nearly complete absence in Melanesia. Contrary to claims of gene flow (under regional continuity) between H. erectus and H. sapiens, we found no ancestral Y chromosome lineages in a set of 1,209 samples. The finding excludes the possibility that early hominids contributed significantly to the paternal heritage of the region.
