Humans colonized various environments in Southeast Asia and Oceania during the Pleistocene



Investigations into what it means to be human have often focused on attempts to uncover the earliest material traces of 'art', 'language', or technological 'complexity'. More recently, however, students have started argue that more attention should be paid to the ecological uniqueness of our species. A new study published in Archaeological Research in Asia reviews the palaecological information associated with hominin dispersals into Southeast Asia and Oceania throughout the Pleistocene (1.25 Ma to 12 ka). Our species' ability to specialize in the exploitation of various and 'extreme' settings in this part of the world stands a strong contrast to the ecological adaptations of other hominin taxa, and reaffirms the utility or exploration of the environmental adaptations or Homo sapiens as an avenue for understanding what it means to be human.

The paper published by scientists from the Max Planck Institute for the Science of Human History focuses on hominin movements across the supposed 'Movius Line' at a boundary previously argued. to separate populations with different cultural and cognitive capacities. While such divisions and assumptions are now clearly outdated, the authors argue that focus on this part of the world may, instead, be used to study the different patterns of colonization of various tropical and maritime habitats by different members of our ancestral line. As Noel Amano, co-author of the study states, 'analysis of biogeochemical records, animal assemblies, and fossil plant records associated with hominin arrival can be used to reconstruct the degree to which novel or specialized adaptations were required at a given place and time '. 'the Hobbit'), and Homo sapiens . As Patrick Roberts, lead author of the study states the accumulated evidence shows, "While earlier members of our genus appear to have followed riverine and lacustrine corridors, Homo sapiens , montane environments, and deep-water marine habitats. The authors hope that, in future, the growth of new methods will determine similar comparisons to different parts of the world, further testing the unique capacities of our species during its global expansion.
