Paleo-health of Neolithic wet-rice farmers in the Yangtze River Delta
Several cases that do not fit the agricultural adaptation model, in which people's health deteriorated with the shift from hunting-gathering to farming, have been reported, such as the introduction of rice agriculture during the Yayoi Period in Japan and the Iron Age in Southeast Asia, where health was maintained or improved. However, the health of rice farmers in the homeland areas has rarely been reported. This study aims to clarify the frequen…
Genomic insights into a tripartite ancestry in the Southern Ryukyu Islands
A tripartite structure for the genetic origin of Japanese populations states that present-day populations are descended from three main ancestors: (1) the indigenous Jomon hunter–gatherers; (2) a Northeast Asian component that arrived during the agrarian Yayoi period; and (3) a major influx of East Asian ancestry in the imperial Kofun period. However, the genetic heterogeneity observed in different regions of the Japanese archipelago highlights t…
The history of ancient Japanese dogs revealed by mitogenomes
Archaeological evidence indicates that dogs appeared in Japan at least 9300 years ago, dur ing the Jomon period. The Jomon period dogs (Jomon dogs) retained the morphological characteristics of ancient domestic dogs throughout the Jomon period, possibly due to their geographical isolation from continental dogs. Therefore, we expect them to retain the genetic characteristics of ancient domestic dogs. To explore this possibility, we determined the …
Complete mitochondrial genome sequencing reveals double-buried Jomon individuals excavated from the Ikawazu shell-mound site were not in a mother–child relationship
A draft whole genome sequence of a Jomon woman from the Ikawazu shell-mound site has been reported recently. The adult woman, IK002, was excavated with a child, IK001. Because of the burial situation with the child located above the adult, the two individuals were thought to be a mother–child relationship. In this study, we conducted a target capture sequencing, and obtained 258-fold coverage of the complete mitochondrial (mt) genome sequence of …
Analysis of ancient human mitochondrial DNA from Verteba Cave, Ukraine
Verteba Cave (VC) in western Ukraine dates to the Eneolithic period (c. 5500 YBP), and contains the largest collection yet found of human skeletal remains associated with the Cucuteni–Tripolye culture. The subsistence economy of this people was based on agropastoralism, and included some of the largest and densest Middle Neolithic settlement sites in all of Europe. To understand further the evolutionary history of the Tripolye people, we examined…
A paleopathological approach to early human adaptation for wet-rice agriculture
The prehistoric peopling of Southeast Asia
Ancient migrations in Southeast Asia The past movements and peopling of Southeast Asia have been poorly represented in ancient DNA studies (see the Perspective by Bellwood). Lipson et al. generated sequences from people inhabiting Southeast Asia from about 1700 to 4100 years ago. Screening of more than a hundred individuals from five sites yielded ancient DNA from 18 individuals. Comparisons with present-day populations suggest two waves of mixin…

From cradle to grave
The life history of a female individual skeleton (ST61) from the Edo period (AD 1603–1868) was investigated by using multi-tissue and multi-isotope analyses. Her gravestone and historical documents revealed that ST61 was a grandmother of a chief retainer of the Akashi clan who died in 1732 aged 77 years. Radiocarbon and sulfur stable isotope analyses indicated that the contribution of marine foods to the ST61 diet was relatively low (17.2% protei…
Radiocarbon dating of one human and two dog burials from the Kamikuroiwa rock shelter site, Ehime Prefecture
Two complete dog skeletons were recovered during archeological excavations from 1961 to 1970 at the Kamikuroiwa rock shelter, a site that yielded a series of cultural entities from the Late Pleistocene, Incipient Jomon, and Early Jomon periods. Since two dogs were buried close to human skeletons, it was thought that these dogs had been buried by Jomon people, and hence provided the oldest direct evidence of Canis domestication in Japan. However, …
Pleistocene human remains from Shiraho-Saonetabaru Cave on Ishigaki Island, Okinawa, Japan, and their radiocarbon dating
Nine human remains were recovered from Shiraho-Saonetabaru Cave on Ishigaki Island, Okinawa Prefecture, Japan, between 2007 and 2009. Six of the nine samples produced well-preserved biogenic collagen, which was submitted to radiocarbon dating by accelerator mass spectrometry. Three human samples (Nos. 2, 4, and 8) from the fossil chamber were dated to between 16 and 20 ka BP, and can clearly be assigned to the Late Pleistocene. One animal bone fr…
