There is evidence of early hominins living in what is now the Philippines as early as 709,000 years ago. A small number of bones from Callao Cave potentially represent an otherwise unknown species, ''Homo luzonensis'', that lived around 50,000 to 67,000 years ago. The oldest modern human remains found on the islands are from the Tabon Caves of Palawan, U/Th-dated to 47,000 ± 11–10,000 years ago. The Tabon Man is presumably a Negrito, who were among the archipelago's earliest inhabitants, descendants of the first human migrations out of Africa via the coastal route along southern Asia to the now sunken landmasses of Sundaland and Sahul.
