Archaeolinguistic evidence for the farming/language dispersal of Koreanic.

While earlier research often saw Altaic as an exception to the farming/language dispersal hypothesis, recent work on millet cultivation in northeast China has led to the proposal that the West Liao basin was the Neolithic homeland of a Transeurasian language family. Here, we examine the archaeolinguistic evidence used to associate millet farming dispersals with Proto-Macro-Koreanic, analysing the identification of population movements in the archaeological record, the role of small-scale cultivation in language dispersals, and Middle-Late Neolithic demography. We conclude that the archaeological evidence is consistent with the arrival and spread of Proto-Macro-Koreanic on the peninsula in association with millet cultivation in the Middle Neolithic.

Ancient genomes from northern China suggest links between subsistence changes and human migration.

Northern China harbored the world's earliest complex societies based on millet farming, in two major centers in the Yellow (YR) and West Liao (WLR) River basins. Until now, their genetic histories have remained largely unknown. Here we present 55 ancient genomes dating to 7500-1700 BP from the YR, WLR, and Amur River (AR) regions.

The evolving Japanese: the dual structure hypothesis at 30.

The population history of Japan has been one of the most intensively studied anthropological questions anywhere in the world, with a huge literature dating back to the nineteenth century and before. A growing consensus over the 1980s that the modern Japanese comprise an admixture of a Neolithic population with Bronze Age migrants from the Korean peninsula was crystallised in Kazurō Hanihara's influential 'dual structure hypothesis' published in 1991. Here, we use recent research in biological anthropology, historical linguistics and archaeology to evaluate this hypothesis after three decades.

Common carp aquaculture in Neolithic China dates back 8,000 years.

Despite the growing importance of farmed fish for contemporary economies, the origins of aquaculture are poorly known. Although it is widely assumed that fish domestication began much later than the domestication of land animals, the evidence is largely negative. Here, we use age-mortality and species-selection profiles of fish bones from prehistoric East Asia to show that managed aquaculture of common carp (Cyprinus carpio) was present at the Early Neolithic Jiahu site, Henan Province, China, by around 6000 BC.

Identification and Characterization of Oral Injury in Suspected Child Abuse Cases: One Health System's Experience.

Objectives: Accurately differentiating inflicted from accidental injury in infants and toddlers is critical. Many studies have documented characteristics of inflicted bruises, fractures, and head injuries facilitating the development of clinical tools. There are few studies characterizing inflicted oral injuries, and no clinical tools exist.

Resilience and the population history of the Kuril Islands, Northwest Pacific: A study in complex human ecodynamics.

Living in remote places can strain the adaptive capacities of human settlers. It can also protect communities from external social, political and economic forces. In this paper, we present an archaeological population history of the Kuril Islands.

Diagnosis and evaluation of causative factors for the presence of endemic treponemal disease in a Japanese sub-tropical island population from the Tokugawa period.

We present a description and differential diagnosis of pathological lesions observed on skeletal elements found during surface surveys of the Nagabaka site on Miyako-jima Island, Japan. The Nagabaka site served as a bone depository during the Early Modern period (c. AD 1600-1870).

Hunter-gatherers and the behavioural ecology of human occupation.

Background: Despite growing interest in indigenous peoples within occupational therapy in Canada and elsewhere, there has been little consideration of hunter-gathering-an occupation that retains great material and symbolic significance for many indigenous groups.

Purpose: A preliminary analysis of occupational behaviour amongst hunter-gatherers was conducted to aid understanding of the nature and evolution of human occupations and inform policy in indigenous occupational therapy.

Methods: Human behavioural ecology was used to analyze four aspects of hunter-gatherer occupations: occupational diversification, the sexual "division of labour," the long dependence of juveniles on adult provisioning, and active foraging by postmenopausal women.

Dental perspectives on the population history of Southeast Asia.

This article uses metric and nonmetric dental data to test the "two-layer" or immigration hypothesis whereby Southeast Asia was initially occupied by an "Australo-Melanesian" population that later underwent substantial genetic admixture with East Asian immigrants associated with the spread of agriculture from the Neolithic period onwards. We examined teeth from 4,002 individuals comprising 42 prehistoric and historic samples from East Asia, Southeast Asia, Australia, and Melanesia. For the odontometric analysis, dental size proportions were compared using factor analysis and Q-mode correlation coefficients, and overall tooth size was also compared between population samples.
