Indigenous people of New Guinea


The indigenous peoples of New Guinea, commonly called Papuans, are Melanesians. There is genetic evidence for two major historical lineages in New Guinea and neighboring islands:
  1. a first wave from the Malay archipelago perhaps 50,000 years ago when New Guinea and Australia were a single landmass called Sahul,
  2. and much later a wave of Austronesian people from the north who introduced Austronesian languages and pigs about 3,500 years ago, and who left a small but significant genetic trace in many coastal Papuan peoples.
Linguistically, Papuans speak languages from the many families of non-Austronesian languages which 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, 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

's 14th edition lists 826 languages of Papua New Guinea and 257 languages of Western New Guinea, total 1073 languages, with 12 languages overlapping. They can be divided into two groups, the Austronesian languages, and all the others, called Papuan languages for convenience. The term Papuan languages refers to an areal grouping, rather than a linguistic one, since so-called Papuan languages comprise hundreds of different languages, most of which are not related.

Genetics

In a 2005 study of ASPM gene variants, Mekel-Bobrov et al. found that the Papuan people have among the highest rate of the newly evolved ASPM Haplogroup D, at 59.4% occurrence of the approximately 6,000-year-old allele. While it is not yet known exactly what selective advantage is provided by this gene variant, the haplogroup D allele is thought to be positively selected in populations and to confer some substantial advantage that has caused its frequency to rapidly increase.
Main Y-DNA Haplogroups of Papuan people are Haplogroup K2b1 and Haplogroup C1b2a with a significant minority of them belong also to Haplogroup O-M175.
