The last region on Earth settled by humans during prehistory was East Polynesia. Hawaiian oral histories mention voyaging from Hawai'i to Tahiti and back via the Tuamotus, an open ocean journey of several thousands of kilometers. The trace element and isotope chemistries of a stone adze recovered from the Tuamotu Archipelago are unlike those of sources in central Polynesia but are similar to the Kaho'olawe Island hawaiite, in the Hawaiian Islands, supporting the oral histories. Other adzes collected from the low coral islands of the northwest Tuamotus have sources in the Marquesas, Austral and Society Islands, and the Pitcairn Group, confirming that trade was widespread within East Polynesia.
人类史前时期在地球上最后定居的地区是东波利尼西亚。夏威夷的口述历史提到从夏威夷航行到塔希提岛，然后经土阿莫土群岛返回，这是一段数千公里的远洋旅程。从土阿莫土群岛回收的一把石斧的微量元素和同位素化学特征与中波利尼西亚的来源不同，但与夏威夷群岛卡霍奥拉韦岛的夏威夷岩相似，这支持了口述历史。从土阿莫土群岛西北部的低珊瑚岛收集的其他石斧来源地为马克萨斯群岛、奥斯塔拉群岛、社会群岛和皮特凯恩群岛，证实了贸易在东波利尼西亚广泛存在。
