Dating the arrival of the first hominins in Java The World Heritage archaeological site at Sangiran on the island of Java in Indonesia has major importance for the understanding of human arrival and evolution in Asia. However, the timing of the first appearance of Homo erectus at the site has been controversial. Using a combination of dating techniques for hominin-bearing sediments, Matsu'ura et al. resolved the arrival of H. erectus at ∼1.3 million years ago (see the Perspective by Brasseur). This dating suggests that the earliest hominins in Sangiran are at least 200,000 years younger than has been thought and may represent an important step to the resolution of the controversy. Science, this issue p. 210; see also p. 147 A combination of dating techniques resolves the arrival of Homo erectus in Indonesia at ~1.3 million years ago. The chronology of the World Heritage Site of Sangiran in Indonesia is crucial for the understanding of human dispersals and settlement in Asia in the Early Pleistocene (before 780,000 years ago). It has been controversial, however, especially regarding the timing of the earliest hominin migration into the Sangiran region. We use a method of combining fission-track and uranium-lead dating and present key ages to calibrate the lower (older) Sangiran hominin-bearing horizons. We conclude that the first appearance datum for the Sangiran hominins is most likely ~1.3 million years ago and less than 1.5 million years ago, which is markedly later than the dates that have been widely accepted for the past two decades.

桑吉兰地区爪哇直立人首次出现数据的年龄控制

确定爪哇第一批人类到达的年代 位于印度尼西亚爪哇岛桑吉兰的世界遗产考古遗址对于了解人类到达亚洲和进化具有重要意义。然而，直立人首次出现在该地点的时间一直存在争议。Matsu'ura 等人对含有古人类的沉积物使用了测年技术的组合。解决了直立人在大约 130 万年前的到来（见 Brasseur 的观点）。这一年代测定表明，桑吉兰最早的古人类至少比人们认为的年轻 20 万年，这可能是解决争议的重要一步。科学，这个问题 p。210; 另见第 147 约会技术的组合解决了直立人在大约 130 万年前到达印度尼西亚的问题。印度尼西亚桑吉兰世界遗产地的年表对于了解早更新世（78 万年前）人类在亚洲的散布和定居至关重要。然而，它一直存在争议，特别是关于最早的人类迁移到桑吉兰地区的时间。我们使用裂变径迹和铀铅测年相结合的方法，并提供关键年龄来校准较低（较旧）的桑吉兰古人类地平线。我们得出的结论是，桑吉兰古人类的首次出现数据很可能是在大约 130 万年前和不到 150 万年前，这明显晚于过去二十年被广泛接受的日期。
