![]() Within this broad geographical framework, the direction and pace of movements of H. The settlement of terrestrial faunas and hominins in Java occurs soon after the transition from marine to more terrestrial environments 2, 4, 11, 13, 27, 28. While it is at present-day largely flooded, Sundaland was permanently continental during Early Pleistocene 6 conversely, while Sundaland was slowly drowning, Java was an uplifting chain of volcanoes emerging from a shallow sea. erectus across Sundaland were conditioned by the extremely transient paleoenvironmental conditions. Second, the subsequent trajectories of Javanese H. erectus directly arrived along the coastlines in a single out-of-Africa episode, or discontinuously stemmed from smaller size groups that expanded earlier in China 25, 26 it implies that early humans could have entered Sundaland from different points in mainland Asia (Fig. First, depending on this age, it is unclear if Javanese H. The burial duration in terrigenous sediments, and exhumation history until sampling, is thus encoded in the sediments by the amount of each isotope they contain.Ī refined knowledge of this time period is crucial to decipher the dispersal and behavior of Javanese H. These isotopes accumulate in the grains when they are exposed to cosmic radiations during exhumation and transport phases, and conversely decay when the grains are shielded during burial periods. ![]() erectus by adding the most reliable age constraints based on cosmogenic nuclides \(^\)Al) in quartz grains from the sedimentary layers of interest. Here, we reappraise the first appearance datum of Javanese H. However, the limited consideration of the rapidly changing physical environment, together with controversial datings of hominin bearing sites, make it challenging to secure the robust timeline needed to unveil the behavior of early humans. The migration of Homo erectus in Southeast Asia during Early Pleistocene is cardinal to our comprehension of the evolution of the genus Homo.
