• The analysis of the 2013 data is not yet complete. Epub 2006 Aug 21. Lum, J. Koji and Gary M. Heathcote. ), while a 'G' in the sub-haplogroup chart includes only the G as a sub-haplogroup (i.e., M201 marker only); 2) Due to varying levels of granularity in the studies combined in these data, there is some ambiguity in the sub-haplogroup results (study X may have taken its haplogrouping to the level of G2a3a, study Y only to G2a, and study Z only to G); the haplogroup results are therefore more definitive than the sub-haplogroup results in the current state of the data. grammatical structure is a better indicator than common vocabulary. 7% (+/- 2.5%) Northern European Anthropology Resource & Research Center This does not mean that Chamorus are Malays. With more than a decade of experience in providing familial DNA Testing worldwide, BSI has become an expert on immigration DNA testing interpretations for government agencies, local embassies, and our immigration clients. Vilar, Miguel G., Chim W. Chan, Dana R. Santos, Daniel Lynch, Rita Spathis, Ralph M. Garruto and J. Koji Lum. Vilar’s research brought him to Guam in August and September 2013 when he participated in the 2nd Marianas History Conference and presented his findings on female lineages which he published in 2012. the testing is complete, a certified copy of the results will be very different. The origins and genetic distinctiveness of the Chamorros of the Marianas Islands: an mtDNA perspective. 2013 Jan-Feb;25(1):116-22. doi: 10.1002/ajhb.22349. These AN speakers clustered "with a diverse grouping of AN Marianas redware shows similarities with other pottery styles of the same period in Southeast Asia and what is known as the Lapita Cultural Complex. The region of Micronesia lies between the Philippines and Hawaii and encompasses more than 2,000 islands, most of which are small and many of which are found in clusters. Vilar’s team found limited genetic diversity among the lineages of the CHamoru subjects.

2017 Mar;62(3):343-353. doi: 10.1038/jhg.2016.147. The diversity of surnames is notable, because they, just as the Y chromosomes, are passed on through males. However, sex cells – eggs and sperm which are used in reproduction – only have half the number of chromosomes, or 23. Like the E1 and E2 haplogroups, the CHamoru mtDNA of the Marianas is found only in these islands, but shows strong links to Island Southeast Asia that possibly date back 4,000-5,000 years ago. inheritance. • The Y-DNA data also suggests a strong connection to Island Southeast Asia, and supports the proposed linguistic hypothesis of Out of Taiwan origin of Austronesian languages.

Bellwood, who wrote the definitive work on the peopling of COVID-19 is an emerging, rapidly evolving situation. [5] (The other Y-DNA haplogroups found were: basal K2* [K-M526], C1b2b [M347; previously Haplogroup C4], and basal C* [M130].). Haplogroup P is a descendant of Haplogroup R.. Distribution. Analysis of mitochondrial DNA (mtDNA) (passed on through females): Analysis of Y Chromosome DNA (passed on through males): On average, CHamorus were: 43% (+/- 4%) Northeast Asian 29% (+/- 3%) Southeast Asian 4% (+/- 1.5%) Oceania, 10% (+/- 3.5%) Mediterranean In Peoples and Cultures of the Pacific, ed. DNA offers a better way to study the relationships among Pacific Islanders. Most species are generally characterized by having a specific number of chromosomes. (Previously the name Haplogroup M was assigned to K2b1d.

Bareic in Sulawesi based on a comparison of standardized word lists (Murdock, Olmo, Richard K. Personal Communication, 1998. After

0.9% (11 individuals) of the sample in a study in which 45% of the total was deemed to be non-indigenous – belonged to haplogroup M1 (M-M4; also known as M-M186 and known previously as haplogroup K2b1d1). Analysis of the specific E1 and E2 haplogroups of the CHamorus showed they were not present outside the Mariana Islands. Vol. Analyses of mitochondrial DNA (mtDNA) sequences reveal that most remote Oceanic populations are polyphyletic. Haplogroup S, as of 2017, is also known as K2b1a. Info, Most tests require 3-way shipping to and from the • The diversity of CHamoru Y-DNA lineages suggests the majority of lineages (60-70%) are prehistoric, however some have a historic origin (Europe, Philippines). K2b1 is a direct descendant of K2b – known previously as Haplogroup MPS.

Mitochondria are inherited from the body of the mother�s fertilized egg, than the rest of Micronesia. Studies of indigenous Australian Y-DNA published in 2014 and 2015, suggest that, before contact with Europeans, about 29% of Australian Aboriginal or Torres Strait Islander males belonged to downstream subclades of K2b1. Most of the remaining CHamoru lineage groups belong to a unique haplogroup labeled B4a1a1a, which is common in Island Southeast Asia and Melanesia. People from Melanesia, a region in the South Pacific encompassing Papua New Guinea and surrounding islands, may carry genetic evidence of a previously unknown extinct hominid species , Ryan Bohlender reported October 20 at the annual meeting of the American Society of Human Genetics. • The mtDNA signature of CHamoru is unique. Both lineages were associated with the last name Cruz. Rare O1 haplotypes, such as O1-F18 and O1-F742, may be Filipino. The limited genetic diversity is consistent with the depopulation of the Marianas which occurred with the arrival and conquest by the Spanish in the 17th century. Miguel Vilar of the University of Pennsylvania is leading a team of scientists in collecting and analyzing DNA samples from modern CHamoru populations to trace the movement patterns and connections with other populations to discover what may have happened in the Marianas. living that defined them as "Chamorros". 1998. Mangilao, Guam: University of Guam,

native of Hong Kong speaks English does not mean that he or she is necessarily Populations.  |  Hum Biol. DNA offers a better way to study the relationships among Pacific Islanders. The northern islands remained empty until they were repopulated by Caroline Islanders in the early 1800s; CHamorus finally were allowed to move back several decades later. Kayser M, Brauer S, Cordaux R, Casto A, Lao O, Zhivotovsky LA, Moyse-Faurie C, Rutledge RB, Schiefenhoevel W, Gil D, Lin AA, Underhill PA, Oefner PJ, Trent RJ, Stoneking M. Mol Biol Evol. However, the Vilar research team also suggests the possibility that the B4 haplogroup may have arrived from neighboring Micronesian islands sometime in the last 2,000 years, and the mutation may have been acquired in the Marianas. Knapp M, Horsburgh KA, Prost S, Stanton JA, Buckley HR, Walter RK, Matisoo-Smith EA. K2b1 is strongly associated with the indigenous peoples of Melanesia (especially the island of New Guinea) and Micronesia, and to a lesser extent Polynesia, where it is generally found only among 5–10% of males. Humans who descend from the same genetic line will share a common SNP. languages spoken within Melanesia. Am J Hum Biol.

Haplogroup B4a1a1a is also the most common group in Central and Eastern Micronesia and Polynesia, and is called the “Polynesia Motif.”. Heathcote, 1998, 5). Murdock, George P. "Genetic Classification of the Austronesian Languages: A K was found in one CHamoru. Notes: 1) In the above charts, haplogroup letter statistics include all sub-groups; sub-haplogroup letter statistics include only that sub-group; e.g., a 'G' in the haplogroup chart includes all G sub-branches (M201 marker plus all progeny; G, G1, G2, etc. Plato Chris C. and M.T. Vilar’s research team analyzed blood and tissue samples of 105 self-identified CHamoru volunteers and 17 Saipan islanders with Carolinian ancestry on their mother’s side.

Micronesian culture, the beliefs and practices of the indigenous peoples of the ethnogeographic group of Pacific Islands known as Micronesia. 10.1002/1096-8644(200010)113:2<151::AID-AJPA2>3.0.CO;2-N. mtDNA and language support a common origin of Micronesians and Polynesians in Island Southeast Asia. ship the kit to, Upon completion of He used the head hair to obtain DNA samples. 1998, 1). The charts on this page depict haplogroup data for the numerically largest ethnic groups residing in this country. Haplogroup O1-P164, showing quite a bit of diversity, was found in 20 CHamorus (48 percent of CHamoru men). Linguists It was found in men with eight different surnames: Camacho, Reyes, Molani, Cepeda, Sablan, Aguon, Flores and Martinez. Lum J. Koji and Rebecca L. Cann.

close mtDNA ties with samples from the Philippines, Borneo, and South China Palauans) mtDNA is most similar to OCAN-speaking Micronesians. "For isntance, would there be close mtDNA similarity Kiribati. Twenty-two of the chromosome pairs are called autosomes. Non-Technical Report Series, no. • The biogeographical component date supports the theory of an origin in Island Southeast Asia, with recent admixture from Europe (in all CHamoru participants). linguistic similarities. This pattern indicates that a founder effect occurred. The genetic information contained in a person’s DNA is hereditary, meaning it is passed down from one generation to the next. The B4 haplogroup was found in only 8 percent of the CHamoru lineages, but 100 percent of the individuals with Carolinian ancestry.

groups from western coastal Thailand (Moken and Urak Lawoi). the OCAN speakers. Micronesians. Both of these groups of islands were colonized within the last 4,000 years by Austronesian-speaking agriculturists.

Topping, Donald, Pedro M. Ogo, and Bernadita C. Dungca. Haplogroup K2b1, known sometimes as haplogroup MS, is a human Y-DNA haplogroup, defined by SNPs P397 and P399. Accessed 14 Oct 2014.

shipped to the Embassy and to you.

The fundamental research question that the Vilar group is trying to answer is whether CHamorus are the direct descendants of a single migration from Island Southeast Asia around 4,000 years ago, or the descendants of a second wave of migrations from Island Southeast Asia about 1,000 years ago. the test, the DNA Identity Testing

This is because, over time, the genetic information spreads through and stabilizes within a population, reducing the amount of deviation. Nagle, N. et al., 2015, "Antiquity and diversity of aboriginal Australian Y-chromosomes", (i. e. individuals indigenous to Oceania are assumed to be K2b1). ", Fill out Immigration DNA Test Application, Sample Based on biogeographic and linguistic patterns, central-eastern Micronesia and Polynesia are included by many in a single category called Remote Oceania. Chromosomes vary in number and shape among different organisms. Chamorus have not mixed much with other Also, the standard deviation of the European and Native American components is much higher than that of the NE Asian and SE Asian components. About 65 percent of the CHamoru individuals had the E2 haplogroup; the low frequency of variations resembled the pattern seen in a young expanding population. He Further analysis and consideration of historical documents will help. Anthropologists based past studies on linguistics.

Russell, Scott.

Embassy in, Bio-Synthesis will The CHamoru group also shared mtDNA mutations characteristic of the E1 and E2 haplogroups, which none of the 17 individuals with Carolinian ancestry showed. of such mixing is indicated (Lum & Heathcote, 1998, 6).
