Linguists and you will archaeologists can be found in standard arrangement the Austronesian dialects originated in Southeast China towards or close Taiwan to 3000 b.c. and therefore Austronesianspeakers spread as a result of Isle Southeast Asia, interacting with Melanesia by 1450 b.c. and you will West Polynesia by the 950 b.c. (Shutler and you can Marck 1975, Bellwood 1978, Blust 198485, Pawley and Ross 1993, Kirch 2000; get a hold of fig. 1). This dispersal, for its rapidity, could have been defined just like the Show Train to help you Polynesia (Diamond 1988). That it design are supported by genetic studies appearing a mostly Far-eastern origin out-of Polynesian mitochondrial DNA (mtDNA) (Melton ainsi que al. 1995, Redd mais aussi al. 1995, Sykes mais aussi al. 1995). Has just, yet not, Kayser et al. (2000) demonstrated a Melanesian resource of Polynesian Y chromosomes favoring a good Slow Motorboat so you’re able to Polynesia design with reasonable populace correspondence components from inside the regards to native nonAustronesian (Papuan) communities during the Melanesia. All of our theory is that the predominance away from maternally sent mtDNA off Far eastern origin as well as the high visibility from paternally carried Y chromosomes of Melanesian origin in the Polynesian origins is accounted for as the an effectation of matrilocal home and you may matrilineal origin within the ProtoOceanic people.
