The Funadomari Jomon people were hunter-gatherers living on Rebun Island, Hokkaido, Japan c. 3500–3800 years ago. In this study, we determined the high-depth and low-depth nuclear genome sequences from a Funadomari Jomon female (F23) and male (F5), respectively. We genotyped the nuclear DNA of F23 and determined the human leukocyte antigen (HLA) class-I genotypes and the phenotypic traits. Moreover, a pathogenic mutation in the CPT1A gene was identified in both F23 and F5. The mutation provides metabolic advantages for consumption of a high-fat diet, and its allele frequency is more than 70% in Arctic populations, but is absent elsewhere. This variant may be related to the lifestyle of the Funadomari Jomon people, who fished and hunted land and marine animals. We observed high homozygosity by descent (HBD) in F23, but HBD tracts longer than 10 cM were very limited, suggesting that the population size of Northern Jomon populations were small. Our analysis suggested that population size of the Jomon people started to decrease c. 50000 years ago. The phylogenetic relationship among F23, modern/ancient Eurasians, and Native Americans showed a deep divergence of F23 in East Eurasia, probably before the split of the ancestor of Native Americans from East Eurasians, but after the split of 40000-year-old Tianyuan, indicating that the Northern Jomon people were genetically isolated from continental East Eurasians for a long period. Intriguingly, we found that modern Japanese as well as Ulchi, Korean, aboriginal Taiwanese, and Philippine populations were genetically closer to F23 than to Han Chinese. Moreover, the Y chromosome of F5 belonged to haplogroup D1b2b, which is rare in modern Japanese populations. These findings provided insights into the history and reconstructions of the ancient human population structures in East Eurasia, and the F23 genome data can be considered as the Jomon Reference Genome for future studies.

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 on others for survival.

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.

In order to further understand the genetic status of the Okhotsk people, who were distributed in southern coastal regions of the Okhotsk Sea during the 5th–13th centuries, nucleotide variations in the hypervariable region (HVR) and the coding regions of mitochondrial DNA (mtDNA) were analyzed. Targeting the coding regions provides reliable genetic information even from ancient DNAs that may have suffered post-mortem damage. MtDNA haplogroups of 38 individuals were classified according to mtDNA lineages known in northeastern Asian people. Comparisons of mtDNA haplogroup frequencies between the Okhotsk people and other Asian populations revealed that the genetic structures of the Okhotsk people are very similar to those of populations currently living around lower regions of the Amur River and the Ainu of Hokkaido. The results support our previous study on molecular phylogeny of mtDNA HVR 1 sequences, and strongly suggest that the Okhotsk people originated around the lower regions of the Amur River and became an intermediate of gene flow from the continental Sakhalin people to the Ainu.

This paper discusses a probable case of pediatric mandibular osteomyelitis (OM) from the east Hokkaido Okhotsk (5th–13th century AD) site of Moyoro, Japan. The remains of a young child present an unusual mandibular lesion exhibiting two main features: (1) cortical thickening reflecting periosteal new bone formation, and (2) lytic alveolar destruction with associated antemortem tooth loss. The lesion was examined macroscopically, microscopically, and via computed tomography imaging. A differential diagnosis—considering lesion appearance, location, and the age of the child—is most consistent with OM, while alveolar and dental involvement suggest an odontogenic source such as an infected tooth germ. The infection appears to have been active at the time of death and chronic (i.e. of 4+ weeks) in duration, an interpretation supported by enamel hypoplastic evidence of physiological stress in the preceding 12–18 months. The lesion’s unique appearance highlights the diverse manifestation of OM, especially in the jaws and in the absence of modern therapeutic treatment. Despite being considered a relatively common condition among non-adult individuals in the past, surprisingly few cases of pediatric OM have been reported from archaeological contexts. This case, only the second documented on a mandible, contributes to the general paucity of paleopathological literature on OM.

Twelve metric variables of the humerus, radius, femur, and tibia were investigated in 11 male samples from northeastern and eastern Asian populations. Variations among regions and correlations between latitude and respective measurements and indices were calculated and a principal component analysis was conducted to elucidate human limb bone characteristics. Significant correlation and marginally significant correlation were found for the maximum subtrochanteric diameter (r = 0.662, P = 0.027) and the platymeric index (r = -0.583, P = 0.060) with latitude, respectively, suggesting that the femur of northern Asians had a wide and flat subtrochanteric shape. The second principal component of the principal component analysis shows that the northeastern samples with comparatively long shaft length and thin and flat shaft diameters were discriminated from the southern samples; the second principal component was significantly correlated with latitude (r = -0.743, P = 0.009). The estimated Fst value of 0.432–0.336 shows that the variation in limb bone measurements across regions is rather large, at approximately two or three times the low levels of interregional variation (0.078–0.180) in analyses of cranial and dental data. Limb bone morphology has been repeatedly proposed to be more strongly influenced by environmental and nutritional factors than cranial and dental traits, but this study is the first to confirm it on the basis of statistical analysis.

In this study, nine nonmetric cranial traits were recorded for ancient human remains excavated at early prehistoric (the late Pleistocene, early Holocene, and Pre-Pottery Neolithic) and late prehistoric (the Neolithic and early Iron age) archeological sites in northern Vietnam. The comparative samples consist of prehistoric and early historic crania from the lower Yangtze River basin, together with recent cranial series from Vietnam, Thailand, South China, and Australia. The results, based mainly on the measure of divergence, are as follows: (1) the early prehistoric northern Vietnam group is distinct from the subsequent inhabitants of northern Vietnam and neighboring populations; (2) the cranial series of northern Vietnam and the surrounding region from the late prehistoric to recent times through early historic period exhibit relative homogeneity, suggesting population continuity; (3) the recent Han Chinese from southern China, one of the possible representatives of East Asians, are relatively distant from all groups from the prehistoric age onwards; and (4) a clear separation of Aboriginal Australians from all the comparative samples, including the early prehistoric northern Vietnamese, is evident. These findings suggest partial support for the two opposing hypotheses, i.e. the two-layer model and the regional-continuity model, for the population history of Southeast Asians, at least, in the northern Vietnamese region. This may be further compatible with the recent hypothesis for modern human dispersals: an earlier out-of-Africa expansion of Australians than other contemporary Eurasians including Southeast Asians.
