New Guinea - People

People

The current population of the island of New Guinea is about 7.5 million. Many believe human habitation on the island dates to as early as 40,000 B.C., and first settlement possibly dated back to 60,000 years ago has been proposed. The island is presently populated by very nearly a thousand different tribal groups and a near-equivalent number of separate languages, which makes New Guinea the most linguistically diverse area in the world. Ethnologue's 14th edition lists 826 languages of Papua New Guinea and 257 languages of Irian Jaya, total 1073 languages, with 12 languages overlapping. They fall into one of two groups, the Papuan languages and the Austronesian languages. The separation was not merely linguistic; warfare among societies was a factor in the evolution of the men's house: separate housing of groups of adult men, from the single-family houses of the women and children, for mutual protection against the other groups. Pig-based trade between the groups and pig-based feasts are a common theme with the other peoples of southeast Asia and Oceania. Most societies practice agriculture, supplemented by hunting and gathering.

The great variety of the island's indigenous populations are frequently assigned to one of two main ethnological divisions, based on archaeological, linguistic and genetic evidence: the Papuan and Austronesian groups.

Current evidence indicates that the Papuans (who constitute the majority of the island's peoples) are descended from the earliest human inhabitants of New Guinea. These original inhabitants first arrived in New Guinea at a time (either side of the Last Glacial Maximum, approx 21,000 years ago) when the island was connected to the Australian continent via a land bridge, forming the landmass known as Sahul. These peoples had made the (shortened) sea-crossing from the islands of Wallacea and Sundaland (the present Malay Archipelago) by at least 40,000 years ago, subsequent to the dispersal of peoples from Africa (circa) 50,000 - 70,000 years ago.

The ancestral Austronesian peoples are believed to have arrived considerably later, approximately 3,500 years ago, as part of a gradual seafaring migration from Southeast Asia, possibly originating in Taiwan. Austronesian-speaking peoples colonized many of the offshore islands to the north and east of New Guinea, such as New Ireland and New Britain, with settlements also on the coastal fringes of the main island in places. Human habitation of New Guinea over tens of thousands of years has led to a great deal of diversity, which was further increased by the later arrival of the Austronesians and the more recent history of European and Asian settlement through events like transmigration. About half of the 2.4 million inhabitants of Indonesian Papua are Javanese migrants.

Large swathes of New Guinea are yet to be explored by scientists and anthropologists. The Indonesian province of West Papua is home to an estimated 44 uncontacted tribal groups.
