How old is Southeast H. erectus believed to be?

Southeast H. erectus, a hominin species, is believed to have a temporal range that places its existence between approximately 1.3 to 1.7 million years ago. This age is supported by archaeological and fossil evidence found in various Southeast Asian sites where fossils associated with H. erectus have been unearthed. Such a timeframe indicates the species was present during a significant period of early human evolution, providing insights into the adaptive strategies and ecological contexts of early human ancestors in this region.

The age range between 1.3 to 1.7 million years allows researchers to understand potential migrations, environmental adaptations, and the evolutionary trajectory of hominins leading up to modern humans. Other age options either fall below or beyond this recognized timeframe, which does not align with the current understanding based on fossil evidence and archaeological findings related to H. erectus in Southeast Asia. This enhances the importance of the chosen timeframe as a significant marker in the study of human evolution.
