  Taiwan was joined to the Asian mainland in the Late Pleistocene, until sea levels rose about 10,000 years ago. Human remains and Paleolithic artifacts dated 20,000 to 30,000 years ago have been found. Study of the human remains suggested they were Australo-Papuan people similar to Negrito populations in the Philippines. Paleolithic Taiwanese likely settled the Ryukyu Islands 30,000 years ago. Slash-and-burn agriculture practices started at least 11,000 years ago.
  
  Stone tools of the Changbin culture have been found in Taitung and Eluanbi. Archaeological remains suggest they were initially hunter-gatherers that slowly shifted to intensive fishing. The distinct Wangxing culture, found in Miaoli County, were initially gatherers who shifted to hunting.
  
  Around 6,000 years ago, Taiwan was settled by farmers of the Dapenkeng culture, most likely from what is now southeast China. These cultures are the ancestors of modern Taiwanese Indigenous peoples and the originators of the Austronesian language family. Trade with the Philippines persisted from the early 2nd millennium BCE, including the use of Taiwanese jade in the Philippine jade culture.
  
  The Dapenkeng culture was succeeded by a variety of cultures throughout the island, including the Tahu and Yingpu; the Yuanshan were characterized by rice harvesting. Iron appeared in such cultures as the Niaosung culture, influenced by trade with China and Maritime Southeast Asia. The Plains Indigenous peoples mainly lived in permanent walled villages, with a lifestyle based on agriculture, fishing, and hunting. They had traditionally matriarchal societies.
