Journey of Man --- Part I

Reading question for National Geographic Article

East/Southeast Asia:  Hopping islands and continents and maybe the largest ocean
Li Jin of Fudan University in Shanghai, China. Asks: When did people first reach Taiwan and Japan? What led to the north-south genetic divide among native populations in East Asia? Did ancient seafarers cross the Pacific from Asia to South America, and if so, where did they embark?
·         The written history of Japan begins with brief references in the 1st century AD Twenty-Four Histories, a collection of Chinese historical texts. However, archaeological evidence indicates that people were living on the islands of Japan as early as the upper Palaeolithic period. Following the last Ice age, around 12,000 BC, the rich ecosystem of the Japanese Archipelago fostered human development. The earliest-known pottery belongs to the Jōmon period.
·         The Upper Palaeolithic (or Late Stone Age) is the third and last subdivision of the Paleolithic or Old Stone Age, as it is understood in Europe, Africa and Asia. Very broadly, it dates to between 50,000 and 10,000 years ago, roughly coinciding with the appearance of behavioral modernity and before the advent of agriculture.
·         In the history of Taiwan, Aboriginal peoples ancestors are believed to have been living on the islands for approximately 8,000 years before major Han Chinese immigration began in the 17th century. The Taiwanese Aborigines are Austronesian peoples, with linguistic and genetic ties to other Austronesian ethnic groups, such as peoples of the PhilippinesMalaysiaIndonesia and Oceania. Taiwan's Austronesian speakers were traditionally distributed over much of the island's rugged central mountain range and concentrated in villages along the alluvial plains. Today, the bulk of the contemporary Taiwanese Aborigine population reside in the mountains and the cities.
