    • Abstract:
      Narratives of "Out of Africa 2"--the expansion of Homo sapiens across Asia--emphasize the pattern of human dispersal but not the underlying processes. In recent years, the main debates have been over the timing and frequency of dispersal. Here, I treat these issues as subordinate to biogeographic ones that affected the behavior of humans in Asia as an invasive species that colonized new environments and had negative impacts on indigenous hominins. I suggest that attention should focus on three issues: (i) geographic factors that molded human dispersal across Asia, (ii) behavioral changes that enabled humans to overcome previously insurmountable barriers, and (iii) demographic considerations of human dispersal and colonization of Asia, including interactions with indigenous competitors. Although a strong case can be made that humans dispersed across southern Asia before 60 ka, this should not detract from attention on the underlying processes of dispersal and colonization.
