A significant number of Micronesians were shown to have paternal genetic relations with Japanese Haplogroup D-M55. Genetic testing found that 9.5% of males from Micronesia as well as 0.2% in East Timor carry what is believed to reflect recent admixture from Japan. That is, D-M116.1 (D1b1) is generally believed to be a primary subclade of D-M64.1 (D1b), possibly as a result of the Japanese military occupation of Southeast Asia during World War II. The 2010 census results of Guam showed 7.1% were white while the 2005 census for Palau showed 8% were European. Smaller numbers at 1.9% in Palau and 1.8% in the Northern Mariana Islands were recorded as "white". In conjunction to the European communities there are large amounts of mixed Micronesians, some of which have European ancestry. The largest group of languages spoken in Micronesia are the Micronesian languages. They are in the family of Oceanic languages, part of the Austronesian language group. They descended from the Proto-Oceanic, which in turn descended via Proto-Malayo-Polynesian from Proto-Austronesian. The languages in the Micronesian family are Marshallese, Gilbertese, Kosraean, Nauruan, as well as a large sub-family called the Trukic–Ponapeic languages containing 11 languages. On the eastern edge of the Federated States of Micronesia, the languages Nukuoro and Kapingamarangi represent an extreme westward extension of the Polynesian branch of Oceanic. Finally, there are two Malayo-Polynesian languages spoken in Micronesia that do not belong to the Oceanic languages: Chamorro in the Mariana Islands and Palauan in Palau. By the time Western contact occurred, although Palau did not have dogs, they did have fowls and maybe also pigs. Nowhere else in Micronesia were pigs known about at that time. Fruit bats are native to Palau, but other mammals are rare. Reptiles are numerous and both mollusks and fish are an important food source. The people of Palau, the Marianas and Yap often chew betel nuts seasoned with lime and pepper leaf. Western Micronesia was unaware of the ceremonial drink, which was called "saka" on Kosrae and "sakau" on Pohnpei.
