Dental characteristics of Tohoku residents in Japan: implications for biological affinity with ancient Emishi

Hirofumi Matsumura, Yukio Dodo

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 117 ( 2 ) 95 - 105 2009.08 [Refereed]

The Population history of Japan has been widely interpreted in terms of an original Jomon occupation from the Neolithic period followed by admixture with Yayoi immigrants associated with the spread of rice farming agriculture From western Japan According to this perspective, the people in areas remote from the western mainland island Of Honshu, Japan Would be less affected by the genes of immigrants This article uses Metric and nonmetric dental data to examine the genetic Influence of Immigrants among the early modern Edo and modern residents in the Tohoku district of northeastern Honshu The results of these dental-trait analyses Suggest a smaller gene flow of immigrants in Tohoku people. as compared to contemporary Japanese in the central and western parts of Japan The metric dental data Imply the gene flow from the west to the north was still due mainly to the males even in recent times. The findings of some Jomon features in the late historic and modern Tohoku tooth samples support the speculation that the ancient inhabitants of this region, in the past referred to as 'Emishi', are people who still have preserved genetic traits of the indigenous people.

Biological affinities of Okhotsk-culture people with East Siberians and Arctic people based on dental characteristics

Hirofumi Matsumura, Hajime Ishida, Tetsuya Amano, Hiroko Ono, Minoru Yoneda

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 117 ( 2 ) 121 - 132 2009.08 [Refereed]

This paper examines the Population affinity of the Okhotsk-culture people who settled along the northeastern coastal areas of the islands of Hokkaido and Sakhalin during the 5th and 11th Centuries, oil the bases of dental metric and nonmetric features Based oil neighbor-joining analyses of both metric and nonmetric data, the Okhostk people, eastern Siberians, and Subarctic American natives were linked more closely to each other than to other East Asian and Pacific samples In particular, the nonmetric data analysis demonstrated the close linkage between the Okhotsk people and tribes ill the Amur River Basin. suggesting that the Okhotsk people were descended From eastern Siberians who might share common ancestry with the present-day Amur people and subarctic Americans Beside the above demonstration of Okhotsk affinities among the populations settling along the Circum Sea of the Okhotsk rim, as far as the metric dental traits are concerned, close resemblances were found between the Okhotsk, Neolithic Jomon, and Hokkaido Ainu However, with regard to their overall dental characteristics. it is not clear whether such odontmetric similarities indicate the evidence Of Substantial genetic interaction between the Okhotsk and Jomon-Ainu lineages, because their nonmetric traits data indicate a quite distant relationship from each other.

Paralysis and severe disability requiring intensive care in Neolithic Asia

Marc F. Oxenham, Lorna Tilley, Hirofumi Matsumura, Lan Cuong Nguyen, Kim Thuy Nguyen, Kim Dung Nguyen, Kate Domett, Damien Huffer

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 117 ( 2 ) 107 - 112 2009.08 [Refereed]

This communication documents one of the earliest verifiable cases of human paralysis associated with severe spinal pathology A series of skeletal abnormalities is described for a young adult male (M9) from a Southeast Asian Neolithic community Differential diagnosis suggests that M9 suffered from a severely disabling congenital fusion of the spine (Klippel-Feil Syndrome, Type III), resulting, in child-onset lower body paralysis at a minimum (maximally quadriplegia). M9 experienced severe, most probably total, incapacitation for at least a decade prior to death In the prehistoric context, this individual's condition would have rendered him completely dependent oil others for survival

Allele frequencies of the ABCC11 gene for earwax phenotypes among ancient populations of Hokkaido, Japan.

Takehiro Sato, Tetsuya Amano, Hiroko Ono, Hajime Ishida, Haruto Kodera, Hirofumi Matsumura, Minoru Yoneda, Ryuichi Masuda

Journal of human genetics ( NATURE PUBLISHING GROUP ) 54 ( 7 ) 409 - 13 2009.07 [Refereed] [International journal]

Human earwax is classified into wet and dry types, which are determined by a single-nucleotide polymorphism in the adenosine triphosphate-binding cassette, sub-family C11 (ABCC11) gene locus. To investigate the allele frequencies of the ABCC11 locus within ancient populations on the Northern Japanese island of Hokkaido, amplified product-length polymorphisms were analyzed for 50 specimens of the Okhotsk people and 35 specimens of the Jomon and Epi-Jomon people excavated from various archaeological sites of Hokkaido. Of these specimens, 31 Okhotsk and 19 Jomon/Epi-Jomon samples were genotyped successfully. Frequencies of the wet-type allele in the Jomon/Epi-Jomon people, considered a major ancestor of the Ainu, were higher than those of other Northeastern Asian populations, including the modern Ainu. By contrast, in the Okhotsk people, believed to originate from East Siberia, frequencies of the dry-type allele were relatively higher than those in the Ainu and Jomon/Epi-Jomon people. These results suggest that gene flow from the Northeastern Asian Continent to descendants of the Jomon/Epi-Jomon people of Hokkaido through the Okhotsk people occurred, resulting in the establishment of the Ainu.

Mitochondrial DNA analysis of Jomon skeletons from the Funadomari site, Hokkaido, and its implication for the origins of Native American.

Noboru Adachi, Ken-ichi Shinoda, Kazuo Umetsu, Hirofumi Matsumura

American journal of physical anthropology ( WILEY-LISS ) 138 ( 3 ) 255 - 65 2009.03 [Refereed] [International journal]

Ancient DNA recovered from 16 Jomon skeletons excavated from Funadomari site, Hokkaido, Japan was analyzed to elucidate the genealogy of the early settlers of the Japanese archipelago. Both the control and coding regions of their mitochondrial DNA were analyzed in detail, and we could securely assign 14 mtDNAs to relevant haplogroups. Haplogroups D1a, M7a, and N9b were observed in these individuals, and N9b was by far the most predominant. The fact that haplogroups N9b and M7a were observed in Hokkaido Jomons bore out the hypothesis that these haplogroups are the (pre-) Jomon contribution to the modern Japanese mtDNA pool. Moreover, the fact that Hokkaido Jomons shared haplogroup D1 with Native Americans validates the hypothesized genetic affinity of the Jomon people to Native Americans, providing direct evidence for the genetic relationships between these populations. However, probably due to the small sample size or close consanguinity among the members of the site, the frequencies of the haplogroups in Funadomari skeletons were quite different from any modern populations, including Hokkaido Ainu, who have been regarded as the direct descendant of the Hokkaido Jomon people. It appears that the genetic study of ancient populations in northern part of Japan brings important information to the understanding of human migration in northeast Asia and America.

Terminal Pleistocene human skeleton from Hang Cho Cave, northern Vietnam: implications for the biological affinities of Hoabinhian people

Hirofumi Matsumura, Minoru Yoneda, Yukio Dodo, Marc F. Oxenham, Nguyen Lan Cuong, Nguyen Kim Thuy, Lam My Dung, Vu The Long, Mariko Yamagata, Junmei Sawada, Kenichi Shinoda, Wataru T. Akigawa

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 116 ( 3 ) 201 - 217 2008.12 [Refereed]

An excavation at the cave site of Hang Cho in northern Vietnam resulted in the discovery of a terminal Pleistocene human skeleton in a relatively good state of preservation. The material culture from this site belongs to the pre-ceramic Hoabinhian period. An AMS radiocarbon date on a tooth sample extracted from this individual gives a calibrated age of 10450 300 years BP. In discussions of the population history of Southeast Asia, it has been repeatedly advocated that Southeast Asia was occupied by indigenous people akin to present-day Australo-Melanesians prior to the Neolithic expansion of migrants from Northeast Asia into the area. Cranial and dental metric analyses were undertaken in order to assess the biological affinity of early settlers in this region. The results suggest that the Hang Cho skeleton, as well as other early or pre-Holocene remains in Southeast Asia, represent descendants of colonizing populations of late Pleistocene Sundaland, who may share a common ancestry with present-day Australian Aboriginal and Melanesian people.

Temporal variation and interaction between nutritional and developmental instability in prehistoric Japanese populations.

Kara C Hoover, Hirofumi Matsumura

American journal of physical anthropology ( WILEY-LISS ) 137 ( 4 ) 469 - 78 2008.12 [Refereed] [International journal]

We examined nutritional and developmental instability in prehistoric Japan, using data from 49 individuals across 13 archaeological sites. Hypoplasia incidence was used as a measure of nutritional stress, and fluctuating asymmetry (of upper facial breath, orbital breadth, and orbital height) as an indirect assessment of developmental instability. Abundant resources due to a stable climate during the Middle Jomon (5,000-3,000 BP) encouraged population growth, which led to regional cultural homogeneity and complexity. A population crash on Honshu in the Late/Final Jomon (roughly 4,000-2,000 BP) led to regionally divergent subsistence economies and settlement patterns. We find that the nutritional stress was consistent between periods, but developmental instability (DI) decreased in the Late/Final Jomon. While the DI values were not statistically significant, the higher values for Middle Jomon may result from sedentism, social stratification, and differential access to resources. On Hokkaido, Jomon culture persisted until the Okhotsk period (1,000-600 BP), marked by the arrival of immigrants from Sakhalin. Nutritional stress was consistent between Middle and Late/Final Jomon, but DI increased in the Late/Final. Nutritional and developmental instability decreased from Late/Final to Okhotsk, suggesting a positive immigrant effect. We expected to find an association between stress markers due to the synergistic relationship between nutrition and pathology. The data support this hypothesis, but only one finding was statistically significant. While high critical values from small sample sizes place limits on the significance of our results, we find that the impact of environmental and cultural change to prehistoric Japanese populations was minimal.

Morphometric affinity of the late Neolithic human remains from Man Bac, Ninh Binh Province, Vietnam: key skeletons with which to debate the 'two layer' hypothesis

Hirofumi Matsumura, Marc F. Oxenham, Yukio Dodo, Kate Domett, Nguyen Kim Thuy, Nguyen Lan Coung, Nguyen Kim dung, Damien Huffer, Mariko Yamagata

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 116 ( 2 ) 135 - 148 2008.08 [Refereed]

The excavation of the Mail Bac site (c. 3800-3500 years BP) in Ninh Birth Province, Northern Vietnam, yielded a large mortuary assemblage. A total of 3 1 inhumations were recovered during the 2004-2005 excavation. Multivariate comparisons using cranial and dental metrics demonstrated close affinities of the Man Bac people to later early Metal Age Dong Son Vietnamese and early and modern samples from southern China including the Neolithic to Western Han period samples from the Yangtze Basin. In contrast, large morphological gaps were found between the Mail Bac people, except for a single individual, and the other earlier prehistoric Vietnamese samples represented by Hoabinhian and early Neolithic Bac Soil and Da But Cultural contexts. These findings suggest the initial appearance of immigrants in northern Vietnam, who were biologically related to pre- or early historic population stocks in northern or eastern peripheral areas, including Southern China. The Mail Bac skeletons support the two-layer hypothesis it discussions pertaining to the population history Of Southeast Asia.

Oral and physiological paleohealth in cold adapted peoples: Northeast Asia, Hokkaido.

Marc F Oxenham, Hirofumi Matsumura

American journal of physical anthropology ( WILEY-LISS ) 135 ( 1 ) 64 - 74 2008.01 [Refereed] [International journal]

This paper examines variables useful in reconstructing oral (caries, antemortem tooth loss, alveolar defects) and physiological (cribra orbitalia, linear enamel hypoplasia) well-being in two bioarchaeological assemblages from Hokkaido, Japan: Okhotsk (n = 37 individuals) and Jomon (n = 60). Findings are compared and contrasted with each other, with published series from Honshu Japan, and samples from climatically near-equivalent Alaska. It was found that more meaningful comparisons of Hokkaido paleohealth could be made with Alaskan material, rather than the more southerly Jomon. Results were ambiguous with respect to physiological well-being. Low levels of LEH in the cold-adapted samples suggest operating in arctic and subarctic environments with marine-based subsistence regimes is not physiologically expensive. However, the relatively high levels of cribra orbitalia in Hokkaido, relative to Alaska, suggest the picture is not straightforward: the reasons for elevated cribra orbitalia in Hokkaido are unclear. The subarctic and arctic samples formed three broadly similar groupings in terms of oral health profiles: (1) Aleuts and Eskimo; (2) Ipiutak and Tigara; (3) Hokkaido Jomon, Okhotsk, and Kodiak Island. Differences between these groupings could be explained with a combination of sample demographics and subsistence orientations. The extremely high frequency of caries in one sample, caribou hunting Ipiutak, may have been influenced by factors such as low levels of dietary magnesium and potentially cariogenic foodstuffs, such as preparations of caribou stomach contents. It was concluded that oral health profiles are potentially sensitive to differences in subsistence strategies among cold-adapted hunter-gatherers, although they lack predictive value.

Non-metric dental trait variation among local sites and regional groups of the Neolithic Jomon period, Japan

Hirofumi Matsumura

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 115 ( 1 ) 25 - 33 2007.04 [Refereed]

Inter-populational heterogeneity of the Neolithic Jomon hunter-gatherers of Japan was examined via 21 non-metric dental traits. Skeletal samples from nine local sites and five regional groups of the middle to final stages of the Jornon period were analyzed, and inter-site comparisons were made among five representative sites (Ubayama, Nakazuma, Ikawazu, Yoshiko, and Tsukumo). Statistically significant differences were found in 4/21 traits in the inter-site comparisons, and in 5/21 traits in the inter-regional comparisons between the Hokkaido, Tohoku, Kanto, Tokai, and Sanyo groups. Smith's distances suggest that the inter-regional differences within the Jomon assemblages are minor when compared with differences from the non-Jomon samples such as the Yayoi immigrants, Kofun, and modem Japanese. Furthermore, examination of the wider geographical variation of the Jornon people (eastern versus western) revealed significant differences in only 2/21 traits. Distance analysis showed that the eastern and western Jomon groups clustered together, and exhibited the greatest affinities with present-day Southeast Asians among comparable East Asian and Pacific population samples. The Jornon people can be collectively regarded as relatively homogeneous, within the broader context of East Asian and Pacific intra-population variation.

Journal of human genetics ( SPRINGER TOKYO ) 52 ( 7 ) 618 - 627 2007 [Refereed] [International journal]

In order to investigate the phylogenetic status of the Okhotsk people that were distributed in northern and eastern Hokkaido as well as southern Sakhalin during the fifth to the thirteenth centuries, DNA was carefully extracted from human bone and tooth remains excavated from archaeological sites. The hypervariable region 1 sequences of the mitochondrial DNA (mtDNA) control region were successfully amplified and 16 mtDNA haplotypes were identified from 37 individuals of the Okhotsk people. Of the 16 haplotypes found, 6 were unique to the Okhotsk people, whereas the other 10 were shared by northeastern Asian people that are currently distributed around Sakhalin and downstream of the Amur River. The phylogenetic relationships inferred from mtDNA sequences showed that the Okhotsk people were more closely related to the Nivkhi and Ulchi people among populations of northeastern Asia. In addition, the Okhotsk people had a relatively closer genetic affinity with the Ainu people of Hokkaido, and were likely intermediates of gene flow from the northeastern Asian people to the Ainu people. These findings support the hypothesis that the Okhotsk culture joined the Satsumon culture (direct descendants of the Jomon people) resulting in the Ainu culture, as suggested by previous archaeological and anthropological studies.

Early historic human remains from the Hasekouji-Shuhen site in Kamakura, Japan

Hirofumi Matsumura, Minoru Yoneda, Hideaki Shudai

ANTHROPOLOGICAL SCIENCE ( ANTHROPOLOGICAL SOC NIPPON ) 114 ( 3 ) 199 - 210 2006.12 [Refereed]

Eight human skeletons in a good state of preservation have been recovered from excavations at the Hasekouji-Shuhen site in Kamakura city, Kanto region, Japan. We conducted AMS radiocarbon dating that revealed the skeletons to belong to the early historic Asuka, Nara, and early Heian periods (circa 670-970 calAD). In terms of their cranial, dental, and limb bone measurements, the Hasekouji-Shuhen skeletons exhibit morphological characteristics that show affinities with the earlier Yayoi series, which are generally considered to represent immigrant populations from the Asian continent. Furthermore, an early indication of dolichocephalization was observed in these early historic people, a trait which became more pronounced in later medieval times. Three adult males have scars that may have been caused by assaults with a spear or a sword-like weapon. One male individual exhibits skeletal abnormalities including multiple cartilaginous exostosis.

Annales de Paleontologie 92 ( 4 ) 367 - 383 2006.10 [Refereed]

We describe two Vietnamese fossiliferous sites located in Hoà Binh province, northern Vietnam. The site of Tan Vinh, first described here, is a quarry opened in Triassic limestone which exposes a karstic network and its filling. One of the fissure filling contained 104 molars of Leopoldamys sabanus (Rodentia, Muridae). The biochronological age of these deposits can be estimated from late Middle Pleistocene to Holocene. The site of Ma U'Oi is a cave opened in a karstified limestone which yielded 56 molars of four species of Muridae in two assemblages: Niviventer andersoni, L. sabanus, Niviventer fulvescens among a mammal fauna dated from late Middle Pleistocene to Late Pleistocene, and L. sabanus, N. fulvescens and Hapalomys delacouri among a microvertebrate fauna dated to the late Middle Pleistocene. First, we present a description of the two sites in terms of sedimentology. Secondly, we compare molars dimensions of the most common murids, L. sabanus and N. fulvescens, recovered at Ma U'Oi and Tan Vinh, with those recovered in a Thai site. The size difference between the specimens of the two species, especially those of L. sabanus in great numbers, from the northern sites and those from the Thai site suggests a cline which can be due to latitudinal differences in palaeotemperatures. The occurrence of N. andersoni, L. sabanus, N. fulvescens in Pleistocene Vietnamese sites allow to update the past distribution of these species. © 2006 Elsevier Masson SAS. All rights reserved.

Which morphology of dry bone articular surfaces suggests so-called fibrous ankylosis in the elderly human sacroiliac joint?

Hidenori Ikeno, Hirofumi Matsumura, Gen Murakami, Toshio J Sato, Makoto Ohta

Anatomical science international ( BLACKWELL PUBLISHING ) 81 ( 1 ) 39 - 46 2006.03 [Refereed] [Domestic journal]

Usually, joint degeneration with aging results in articular cartilage defects, which results in bony ankylosis. However, the sacroiliac articular cartilage is maintained even in the elderly and the fibrous tissues make so-called 'fibrous ankylosis'. Macroscopically and histologically, we observed two sacroiliac joints obtained from one young cadaver as well as 23 sacroiliac joints from 23 elderly cadavers. Each joint was divided into two pieces along the long axis: one half was processed for routine histology after decalcification, whereas the other half was macerated to provide a dry bone specimen. The articular cartilage consistently contained abundant fibers and some of the fibers connected to tight intra-articular fiber bands. Fiber insertion into the thin subchondral bone displayed a tidemark in a spotty manner. Thus, the calcified fibrocartilage seemed to be present and seemed to provide fine granularity on the dry bone specimen. The joint cavity was sometimes closed with fibrocartilage-like tissues: we termed this complete fibrous ankylosis. The dry bone specimen corresponding to complete fibrous ankylosis exhibited significant microporosity and granularity because of fragmented subchondral bone. Moreover, bony ankylosis along the sacroiliac joint margin also contained fibrocartilage-like tissues. Therefore, complete fibrous ankylosis is also likely to be the preliminary step to bony ankylosis in the entire joint area. Consequently, microporosity with granularity seemed to be the most critical anthropological characteristic for estimation of sacroiliac joint movability.
