Language continuity despite population replacement in Remote Oceania

Cosimo Posth etc.

Abstract
Recent genomic analyses show that the earliest peoples reaching Remote Oceania—associated with Austronesian-speaking Lapita culture—were almost completely East Asian, without detectable Papuan ancestry. However, Papuan-related genetic ancestry is found across present-day Pacific populations, indicating that peoples from Near Oceania have played a significant, but largely unknown, ancestral role. Here, new genome-wide data from 19 ancient South Pacific individuals provide direct evidence of a so-far undescribed Papuan expansion into Remote Oceania starting ~2,500 yr BP, far earlier than previously estimated and supporting a model from historical linguistics. New genome-wide data from 27 contemporary ni-Vanuatu demonstrate a subsequent and almost complete replacement of Lapita-Austronesian by Near Oceanian ancestry. Despite this massive demographic change, incoming Papuan languages did not replace Austronesian languages. Population replacement with language continuity is extremely rare—if not unprecedented—in human history. Our analyses show that rather than one large-scale event, the process was incremental and complex, with repeated migrations and sex-biased admixture with peoples from the Bismarck Archipelago.

古代瓦卢阿图的拉皮塔人常染几乎和台湾泰雅族、菲律宾北部山区的igorot人没有区别,都是100%的南东亚成分。现代瓦卢阿图人应该是混入了大量的巴布亚常染,已经洗成美拉尼西亚人了

现代毛利人与欧洲人混血严重,不过除去西欧亚成分,整体是以南东亚成分和巴布亚成分为主

里面两例明确的O,根据原始数据来看,其中的O1a1a1a是F78-、YP4610-,O2a2b2a可以往下继续分到O2a2b2a2b-AM01847+、A17436-

相关课题之前本坛已有讨论,而且‘博士’同志也是主要作者之一,看看这次‘博士’单飞搞出来的结果有什么不同,等一下坐下来慢慢看...

没看到原文,只看到附件,这次比上次补充了许多aDNA数据,可喜的进步,马普所的技术就是非同凡响,再次祝贺!

看得出来,这种‘替代’是一个渐进的过程,也提示经过前期大规模的东扩之后,南岛语人群后继无力,逐渐被美兰尼西亚土著‘淹没’了,尽管仍然留下一些南岛人的y与mt,再次提示把y/mt与人种挂钩是多么的不靠谱~

蚵仔煎的确是闽南语人群的一道令人垂涎的美食。说起蚵蠔蚝牡蛎海蛎子,这个无疑是远古沿海地区人类的日常高营养美食,在东亚地区尤甚,可能是此地的高产量有关。说起蚵蠔蚝以及英语oyster,这个词汇无疑是早期人类的基本词汇之一,现在看来应该是同源词,比如印欧人的这个词汇有两个源头,一个是oyster来自印欧语的ost(<khost? 本意壳,应该与蠔蚝同源),另一个shell来自印欧语的skel(无疑与汉语的壳同源)。说明印欧语与汉语一样,也是明显的混合语,而且同源词的发展与汉语的发展也是类似的。


当年南岛人来到拉皮塔,带来了他们的语言与文化,不过最终还是融入当地人的‘汪洋大海’之中,尽管留下了他们的语言以及y/mt,而绝大多数基因却被当地人漂掉了,非常类似现在的火鸡国和南亚某些民系~

当年的拉皮塔南岛殖民者,高度酷似我的一湖北朋友,反而在现代的台湾土著中不多见,也是蛮有意思的~

其实金发和红发在当地土著中是蛮普遍的,非常有趣~
