长期以来，考古学家一直在争论所有波利尼西亚人和美拉尼西亚岛许多人口的直接祖先的起源和传播方式。这些争论与年代框架有着千丝万缕的联系，而年代框架的一部分是由放射性碳年代测定提供的。人类遗骸最有可能为与这些辩论有关的许多问题提供答案。不幸的是，由于骨降解、样品预处理和饮食，骨是迄今为止可靠的最复杂的材料之一。这在太平洋地区尤其令人担忧，因为那里的湿度会导致骨蛋白的快速腐烂，并且海洋、珊瑚礁、C4、C3和淡水食物的组合使14C测定的解释复杂化。骨预处理，同位素多变量建模和放射性碳校准技术的独立进展，为我们提供了第一次，与工具，以获得可靠的校准年龄的太平洋埋葬。在这里，我们提出了结合这些技术的研究，使我们能够重新评估太平洋主要考古遗址的墓葬年龄。
Archaeologists have long debated the origins and mode of dispersal of the immediate predecessors of all Polynesians and many populations in Island Melanesia. Such debates are inextricably linked to a chronological framework provided, in part, by radiocarbon dates. Human remains have the greatest potential for providing answers to many questions pertinent to these debates. Unfortunately, bone is one of the most complicated materials to date reliably because of bone degradation, sample pre-treatment and diet. This is of particular concern in the Pacific where humidity contributes to the rapid decay of bone protein, and a combination of marine, reef, C4, C3and freshwater foods complicate the interpretation of14C determinations. Independent advances in bone pre-treatment, isotope multivariate modelling and radiocarbon calibration techniques provide us, for the first time, with the tools to obtain reliable calibrated ages for Pacific burials. Here we present research that combines these techniques, enabling us to re-evaluate the age of burials from key archaeological sites in the Pacific.
