  There is evidence of early hominins living in what is now the Philippines as early as 709,000 years ago. Bones from Callao Cave potentially represent an otherwise unknown species, Homo luzonensis, who lived 50,000 to 67,000 years ago. The oldest modern human remains on the islands are from the Tabon Caves of Palawan, U/Th-dated to 47,000 ± 11–10,000 years ago. Tabon Man is presumably a Negrito, among the archipelago's earliest inhabitants descended from the first human migrations out of Africa via the coastal route along southern Asia to the now-sunken landmasses of Sundaland and Sahul.
  
  The first Austronesians reached the Philippines from Taiwan around 2200 BC, settling the Batanes Islands (where they built stone fortresses known as ijangs) and northern Luzon. Jade artifacts have been dated to 2000 BC, with lingling-o jade items made in Luzon with raw materials from Taiwan. By 1000 BC, the inhabitants of the archipelago had developed into four societies: hunter-gatherer tribes, warrior societies, highland plutocracies, and port principalities.
