This study examines y chromosome haplogroup D2a1 is significantly associated with high levels of luteinizing hormone in Japanese men. It is catalogued here as comparative evidence within d-m174 and y-chromosome phylogeny.
Genetic structure of Qiangic populations residing in the western Sichuan corridor
The Qiangic languages in western Sichuan (WSC) are believed to be the oldest branch of the Sino-Tibetan linguistic family, and therefore, all Sino-Tibetan populations might have originated in WSC. However, very few genetic investigations have been done on Qiangic populations and no genetic evidences for the origin of Sino-Tibetan populations have been provided.
Jomon Culture and the peopling of the Japanese archipelago: advancements in the fields of morphometrics and ancient DNA
Archaeological investigation of the Jomon Culture is extensive and well supported among the Japanese public. The distinct pottery that characterizes the Jomon has been well documented and physical anthropological description of skeletal remains in Japan has a long and extensive history. However, questions remain of Jomon peoples origins, biological contribution to modern Japanese and biological relationship to the agriculturalist people associated with the Yayoi culture.
Overview of genetic variation in the Y chromosome of modern Japanese males
Japanese people are widely believed to be the descendants of the Jomon and Yayoi people. The dual-structure model, which attempts to explain the formation of the Japanese population, hypothesizes that the indigenous Jomon people migrated from the northern island of Hokkaido and the Ryukyu Islands to the other islands of Japan, where they resided before the Yayoi started to arrive in Kyushu (the westernmost main island of the Japanese archipelago) from the Korean peninsula.
Ancient DNA Analyses of Human Skeletal Remains from the Gusuku Period in the Ryukyu Islands, Japan
Identifying genetic characteristics of the Gusuku period is indispensable to clarifying the colonizing process of the Ryukyu Islands and formation of the modern Ryukyu population. However, no genetic information on this period has hitherto been reported. In the present study, we analyzed ancient DNA recovered from Gusuku skeletons excavated from Okinawa Island (Nakandariyama site) and Hateruma Island (Moubaru site).
Genetic Evidence of Paleolithic Colonization and Neolithic Expansion of Modern Humans on the Tibetan Plateau
Tibetans live on the highest plateau in the world, their current population size is approximately 5 million, and most of them live at an altitude exceeding 3,500 m. Therefore, the Tibetan Plateau is aremarkable area for cultural and biological studies of human population history. However, the chronological profile of the Tibetan Plateau’s colonization remains an unsolved question of human prehistory.
Japanese north-south gradient in IQ predicts differences in stature, skin color, income, and homicide rate
history: Received April 2013 Received in revised form June 2013 Accepted July 2013 Available online July 2013 Regional differences in IQ are estimated for 47 prefectures of Japan. IQ scores obtained from official achievement tests show a gradient from north to south. Latitudes correlate with height, IQ, and skin color at r = 0.70, 0.44, 0.47, respectively.
mtDNA from the Early Bronze Age to the Roman Period Suggests a Genetic Link between the Indian Subcontinent and Mesopotamian Cradle of Civilization
Ancient DNA methodology was applied to analyse sequences extracted from freshly unearthed remains (teeth) of 4 individuals deeply deposited in slightly alkaline soil of the Tell Ashara (ancient Terqa) and Tell Masaikh (ancient KarAssurnasirpal) Syrian archaeological sites, both in the middle Euphrates valley.
Y Chromosome Haplogroup D2* Lineage Is Associated with Azoospermia in Japanese Males
This study examines y Chromosome Haplogroup D2* Lineage Is Associated with Azoospermia in Japanese Males. It is catalogued here as comparative evidence within health and phenotypic associations.
Autosomal and Y-chromosomal STR markers reveal a close relationship between Hokkaido Ainu and Ryukyu islanders
Understanding the phylogenetic relationship between Hokkaido Ainu and Ryukyu islanders has been of great interest in human genetics, ar chaeology, and anthropology. We examined short tandem repeat (STR) polymorphisms on autosomes a nd Y-chromosomes for Ainu, and compared this with data from Ryukyu islanders. A statistical test for nine autosomal (A-STR) loci gave no indication that the Ainu had experienced any bottleneck effect(s).
Geographical Distribution of Adolescent Body Height with Respect to Effective Day Length in Japan: An Ecological Analysis
The height of Japanese youth raised in the northern region tends to be greater than that of youth raised in the southern region; therefore, a geographical gradient in youth body height exists. Although this gradient has existed for about 100 years, the reasons for it remain unclear. Consideration of the nutritional improvement, economic growth, and intense migration that has occurred in this period indicates that it is probably the result of environmental rather than nutritional or genetic factors.
The history of human populations in the Japanese Archipelago inferred from genome-wide SNP data with a special reference to the Ainu and the Ryukyuan populations
This study examines the history of human populations in the Japanese Archipelago inferred from genome-wide SNP data with a special reference to the Ainu and the Ryukyuan populations. It is catalogued here as comparative evidence within ancient dna and archaeogenomics.
Extended Y chromosome investigation suggests postglacial migrations of modern humans into East Asia via the northern route
Genetic diversity data, from Y chromosome and mitochondrial DNA as well as recent genome-wide autosomal single nucleotide polymorphisms, suggested that mainland Southeast Asia was the major geographic source of East Asian populations. However, these studies also detected Central-South Asia (CSA)- and/or West Eurasia (WE)-related genetic components in East Asia, implying either recent population admixture or ancient migrations via the proposed northern route.
Inland post-glacial dispersal in East Asia revealed by mitochondrial haplogroup M9a’b
This study examines inland post-glacial dispersal in East Asia revealed by mitochondrial haplogroup M9a’b. It is catalogued here as comparative evidence within japan, ainu, ryukyu and the jomon.
