黄土高原环县黄土古气候数据集（28万年以来）

由于缺乏对亚洲古人类学和古气候数据的协调综合，智人最初从非洲向东亚的传播与亚洲夏季风（ASM）（目前最大的季风系统）的轨道演化之间的关系仍有待探索。在这里，我们通过整合（1）来自中国黄土高原的新的百年分辨率ASM记录，（2）基于模型的东亚水文气候重建，（3）古人类学数据汇编，和（4）全球智人栖息地适宜性模拟，研究了过去28万年（kyr）的轨道尺度ASM动力学及其对早期智人向东亚传播的可能影响。

Due to the lack of coordinated synthesis of Asian paleoanthropological and paleoclimatic data, the relationship between the initial eastward dispersal of *Homo sapiens* from Africa to East Asia and the orbital evolution of the Asian Summer Monsoon (ASM)—the largest monsoon system currently on Earth—remains to be explored. Here, we investigate the orbital-scale dynamics of the ASM over the past 280 thousand years (kyr) and its potential impacts on the eastward dispersal of early *Homo sapiens* into East Asia by integrating four components: (1) new centennial-resolution ASM records from the Chinese Loess Plateau, (2) model-based hydroclimatic reconstructions for East Asia, (3) compiled paleoanthropological datasets, and (4) global habitat suitability simulations for *Homo sapiens*.
