Indigenous people of New Guinea

The Indigenous peoples of Papua New Guinea and of Western New Guinea in Indonesia, commonly called Papuans, are Melanesians. There is genetic evidence for two major historical lineages in New Guinea and neighboring islands: a first wave from the Malay Archipelago perhaps 50,000 years ago when New Guinea and Australia were a single landmass called Sahul and, much later, a wave of Austronesian people from the north who introduced Austronesian languages and pigs about 3,500 years ago. They also left a small but significant genetic trace in many coastal Papuan peoples.

Linguistically, Papuans speak languages from the many families of non-Austronesian languages that are found only on New Guinea and neighboring islands, as well as Austronesian languages along parts of the coast, and recently developed creoles such as Tok Pisin, Hiri Motu, Unserdeutsch, and Papuan Malay.

The term "Papuan" is used in a wider sense in linguistics and anthropology. In linguistics, "Papuan languages" is a cover term for the diverse, mutually unrelated, non-Austronesian language families spoken in Melanesia, the Torres Strait Islands, and parts of Wallacea. In anthropology, "Papuan" is often used to denote the highly diverse aboriginal populations of Melanesia and Wallacea prior to the arrival of Austronesian-speakers, and the dominant genetic traces of these populations in the current ethnic groups of these areas.

Languages

Ethnologue's 14th edition lists 826 languages of Papua New Guinea and 257 languages of Western New Guinea, a total of 1083 languages, with 12 languages overlapping. If we adopt the figure proposed by Glottolog for Papua New Guinea, namely 928 languages, the total is even higher. This corresponds to 15% of the world's 7700 languages.
