Prehistory and Gojoseon
]
No definite Homo erectus has been found in the Korean Peninsula, though a possible Homo erectus has been reported. Tool-making artifacts from the Palaeolithic period have been found in present-day North Hamgyong, South P'yongan, Gyeonggi, and north and south Chungcheong Provinces of Korea., which dates the Paleolithic Age to half a million years ago, though it may have begun as late as 400,000 years ago or as early as 600,000-700,000 years ago. The predominant view is that the Korean people of today are not the ethnic descendants of these Paleolithic inhabitants.
