Variation in Mitochondrial DNA of Vietnamese Pigs: Relationships with Asian Domestic Pigs and Ryukyu Wild Boars

Mitochondrial DNA (mtDNA) sequences (574 bp) of 30 Vietnamese pigs (large and small) were examined and compared with those of 61 haplotypes from wild boars and domestic pigs from various locations in Asia. The large Vietnamese pigs had genetic links to Ryukyu wild boars in southern Japan. The small Vietnamese pigs were closely related to other East Asian domestic pigs. These results indicate that Vietnamese pigs are genetically diverse and may be descendents of wild and domestic pigs from other regions of Asia

Ancient Jomon genome sequence analysis sheds light on migration patterns of early East Asian populations

Anatomically modern humans reached East Asia more than 40,000 years ago. However, key questions still remain unanswered with regard to the route(s) and the number of wave(s) in the dispersal into East Eurasia. Ancient genomes at the edge of the region may elucidate a more detailed picture of the peopling of East Eurasia. Here, we analyze the whole-genome sequence of a 2,500-year-old individual (IK002) from the main-island of Japan that is characterized with a typical Jomon culture. The phylogenetic analyses support multiple waves of migration, with IK002 forming a basal lineage to the East and Northeast Asian genomes examined, likely representing some of the earliest-wave migrants who went north from Southeast Asia to East Asia. Furthermore, IK002 shows strong genetic affinity with the indigenous Taiwan aborigines, which may support a coastal route of the Jomon-ancestry migration. This study highlights the power of ancient genomics to provide new insights into the complex history of human migration into East Eurasia

[Article] Determination of the Radiocarbon (14C) Age for the Specimens of Wolves from Kuzuu, Tochigi Prefecture in the Nobuo Naora Collection of the National Museum of Japanese History, and the Temporal Changes in the Size of the Lower First Molars of Wolves of the Japanese Archipelago

国立歴史民俗博物館に収蔵されている（故）直良信夫収集の栃木県佐野市葛生から産出したオオカミ（Canis lupus sspp.）の標本4点について，加速器質量分析計（AMS）による放射性炭素（14C）年代測定を行って，それぞれの個体の生息年代を明らかにした。また，14C年代測定によって年代が明らかとなった更新世以降の日本列島のオオカミを，個々の正確な生息年代で時間軸上に並べ，それぞれの下顎第一臼歯の近遠心径の大きさを指標として経時的な変化の様相を検討した。その結果，更新世の化石オオカミと現生ニホンオオカミとの間には明らかな大きさの相違と時間軸上での不連続が認められ，ニホンオオカミは更新世オオカミが小型化した「直系子孫」とは考えにくく，さらなる検証が必要であるとの結論を得た。The radiocarbon (14C) age for four wolf specimens (NMJH A-636-1-1-18-1, A-636-1-1-18-4, A-636-1-1-19-1, and A-636-1-2-41-2) that were collected by Nobuo Naora in 1940s-1960s from the fissure deposits in Kuzuu, Sano City, Tochigi Prefecture in the Nobuo Naora’s collection at The National Museum of Japanese History were measured by Accelerated Mass Spectrometry (AMS). As a result, NMJH A-636-1-1-18-1 was unmeasurable as over background, suggesting that it was thought to be of the middle Late Pleistocene or much older in age: in fact it was strongly fossilized. NMJH A-636-1-1-18-4 was initially thought to be of the period between the latest Early Pleistocene and the Middle Pleistocene by Naora himself, but it was measured as the late Late Pleistocene (33645 ±238 BC). NMJH A-636-1-1-19-1 was also initially thought to be the same age as NMJH A-636-1-1-18-4, but it turned out to be a slightly older than the previous thought, i.e., the late Late Pleistocene (35626±481 BC). NMJH A-636-1-2-41-2 had long been thought to be from the Kofun Period (Mid 3rd century or 7th century) by Naora, but it was measured as an age of the Middle Jomon period (5008±74 BC). In addition, fossils and remains of wolves from the Japanese Archipelago after the late Late Pleistocene (younger than 50 Ka), whose ages were revealed by 14C dating, were compared based on the size of the lower first molar (M1) through time, and the mesiodistal diameters of each M1 were compared with each other to consider the chronological changes of their sizes. As a result, discontinuity of the M1 size between the fossils older than 12 Ka and the remains younger than 12 Ka was recognized. Furthermore, comparing the proportion (rectangle) of the M1s in mesiodistal by buccolingual diameters in occlusal view, the buccolingual diameter is larger and thicker compared to the mesiodistal diameter in fossil wolves, but there tended to be smaller and thinner in the Japanese wolves. We concluded that the Japanese wolf was not a “direct descendant” of the Pleistocene wolf known from the Honshu Island.departmental bulletin pape
