Papua New Guinea
The ancient inhabitants of New Guinea and its outlying islands have played an essential role in the population history of Oceania and adjacent regions. However, inferences about the genetic history of Near Oceania are solely made from present-day people, with no ancient genomes available from New Guinea to date. Present-day coastal populations of Papua New Guinea (PNG) harbour East Asian-related ancestry, raising questions regarding the source of this genetic component and the date of admixture with local populations. In this study, we analyse ancient genetic, isotopic and microfossil data of individuals from three archaeological sites from mainland PNG and one site from the Bismarck Archipelago (Watom Island). Our time transect in the Bismarck Archipelago (~2700-500 years before present (BP)) reveals the presence of people with local 87Sr/86Sr-isotopic values and Papuan-related ancestry dating from 2700-2600 BP. The east Asian ancestry component is inferred to admix with Papuan-related ~2100BP, over a millennium after the earliest occurrence of the Lapita cultural complex on the Bismarck Archipelago. Three coastal sites of mainland PNG date to the last 700 years, and show that people on the coasts of Papua New Guinea were involved in diverse and complex interaction spheres, contributing to the genetic variation observed today. The multidisciplinary comparison of two very nearby, and roughly contemporaneous sites on the southern coast shows different interactions spheres, possibly reflected in the linguistic and cultural diversity observed today. An IBD-based method reveals that the populations of two geographical proximal sites split ~650 years ago, coinciding with a period of intensified settlement activities and trade, perhaps providing an example of shifting societal interactions related to changing environmental circumstances.
新几内亚及其外围岛屿的古代居民在大洋洲和邻近地区的人口历史中发挥了重要作用。然而，关于近大洋洲遗传历史的推断完全是基于当今的人们，迄今为止新几内亚没有古代基因组。巴布亚新几内亚 (PNG) 的当今沿海人口拥有与东亚相关的血统，这引发了人们对这种遗传成分的来源以及与当地人口混合的日期的疑问。在本研究中，我们分析了来自巴布亚新几内亚大陆三个考古遗址和俾斯麦群岛 (Watom Island) 一个遗址的个体的古代遗传、同位素和微化石数据。我们在俾斯麦群岛 (约 2700-500 年前 (BP)) 的时间横断面揭示了具有当地 87Sr/86Sr 同位素值和巴布亚相关血统的人的存在，其血统可追溯到 2700-2600 年前。推测东亚血统成分与巴布亚相关的约 2100BP 混合，这距俾斯麦群岛上最早出现的拉皮塔文化复合体已有一千多年。巴布亚新几内亚大陆的三个沿海遗址可追溯到最近 700 年，表明巴布亚新几内亚海岸的人们参与了多样而复杂的互动领域，导致了今天观察到的遗传变异。对南部海岸两个非常接近且大致同时期的遗址进行多学科比较，显示出不同的互动领域，这可能反映在今天观察到的语言和文化多样性中。基于 IBD 的方法表明，两个地理上相近的遗址的人口在约 650 年前分裂，恰逢定居活动和贸易加强的时期，或许提供了一个与环境情况变化相关的社会互动转变的例子。
