Front Speed Of Language Replacement, Joaquim Fort, Joaquim Pérez-Losada
Front Speed Of Language Replacement, Joaquim Fort, Joaquim Pérez-Losada
Human Biology Open Access Pre-Prints
We use two coupled equations to analyze the space-time dynamics of two interacting languages. Firstly, we introduce a cohabitation model, which is more appropriate for human populations than classical (non-cohabitation) models. Secondly, using numerical simulations we nd the front speed of a new language spreading into a region where another language was previously used. Thirdly, for a special case we derive an analytical formula that makes it possible to check the validity of our numerical simulations. Finally, as an example, we nd that the observed front speed for the spread of the English language into Wales in the period 1961-1981 …

We reviewed data collected during several studies concerning the genetic isolate of Carloforte (Sardinia, Italy) and analyzed new data on Y-chromosome markers. Carloforte is also a language island, where people still speaks Tabarchino, an archaic form of Ligurian dialect. Demographic data indicate that, in the early years of its history, Carloforte population was characterized by a high degree of endogamy and consanguinity rates that started to decrease around 1850, when marriages with Sardinian people began to occur more frequently. Cultural factors, mainly language, account for the high endogamy. Genetic data from classical markers, mtDNA and Ychromosome markers confirmed the strong …
Genetic Characteristics Of An Ancient Nomadic Group In Northern China, Haijing Wang, Lu Chen, Binwen Ge, Ye Zhang, Hong Zhu, Hui Zhou
Genetic Characteristics Of An Ancient Nomadic Group In Northern China, Haijing Wang, Lu Chen, Binwen Ge, Ye Zhang, Hong Zhu, Hui Zhou
Human Biology Open Access Pre-Prints
Nomadic populations have played a significant role in the history of not only China but also in many nations worldwide. Because they had no written language, an important aspect in the study of these people is the discovery of their tombs. It has been generally accepted that Xiongnu was the first empire created by nomadic tribe in the 3rd century B.C. However, little population genetic information is available concerning the Donghu, another flourishing nomadic tribe at the same period because of the restriction of materials until Jinggouzi site was excavated. In order to test the genetic characteristics of ancient people …
Paternal Lineage Analysis Supports An Armenian Rather Than A Central Asian Genetic Origin Of The Hamshenis, Ashot Margaryan, Ashot Harutyunyan, Zaruhi Khachatryan, Armine Khudoyan, Levon Yepiskoposyan
Paternal Lineage Analysis Supports An Armenian Rather Than A Central Asian Genetic Origin Of The Hamshenis, Ashot Margaryan, Ashot Harutyunyan, Zaruhi Khachatryan, Armine Khudoyan, Levon Yepiskoposyan

The Hamshenis are an isolated geographic group of Armenians with a strong ethnic identity who, until the early decades of the twentieth century, inhabited the Pontus area on the southern coast of the Black Sea. Scholars hold alternative views on their origin, proposing eastern Armenia, western Armenia and Central Asia, respectively, as their most likely homeland. To ascertain whether genetic data from the non-recombining portion of the Y chromosome is supportive any of these suggestions, we screened 82 Armenian males of the Hamsheni descent for 12 biallelic and 6 microsatellite Y-chromosomal markers. These data were compared with the corresponding datasets …
Resource Availability, Mortality And Fertility: A Path Analytic Approach To Global Life History Variation, Mark A. Caudell, Robert J. Quinlan
Resource Availability, Mortality And Fertility: A Path Analytic Approach To Global Life History Variation, Mark A. Caudell, Robert J. Quinlan
Human Biology Open Access Pre-Prints
Humans exhibit considerable diversity in timing and rate of reproduction. Life history theory suggests that ecological cues of resource richness and survival probabilities shape human phenotypes across populations. Populations experiencing high extrinsic mortality due to uncertainty in resources should exhibit faster life histories. Here we use a path analytic approach informed by life history theory to model the multiple pathways between resources, mortality rates, and reproductive behavior in 191 countries. Resources that account for the most variance in population mortality rates are predicted to explain the most variance in total fertility rates. Results indicate that resources (e.g., calories, sanitation, education, …
Association Among Obesity-Related Anthropometric Phenotypes: Analyzing Genetic And Environmental Contribution, Aline Jelenkovic, Esther Rebato
Association Among Obesity-Related Anthropometric Phenotypes: Analyzing Genetic And Environmental Contribution, Aline Jelenkovic, Esther Rebato
Human Biology Open Access Pre-Prints
Obesity has become a public health and policy problem in many parts of the world. Epidemiological and population studies in this field are usually based on different anthropometric measures, however, common genetic and environmental factors between these phenotypes have been scarcely studied. The objective of this work is to assess the strength of these factors on the covariation among a large set of obesity-related traits. The subject group consisted of 533 nuclear families living in the Greater Bilbao (Spain), and included 1702 individuals aged 2-61 years. Detailed anthropometric measurements (stature, breadths, circumferences and skinfolds) were carried out in each subject. …

This study analysed the variations in space of 8 body dimensions and 11 measures of the head of 1,244 adult Yemenite males, collected in 1933/34 by Coon in Yemen and in Hadhramawt. The aim was to evaluate the presence of geographic microdifferentiation of the populations settled in the different regions of Yemen at the time. Coon sub-divided the sample into 6 geographical areas according to birthplace and ethnicity of the individuals: Tihamah, the Western Mountains, the Central Plateau, the South Coast, the Eastern Mountains and Hadhramawt. The results of ANCOVA (age as covariate) show that the observed differences of all …

A recent workshop on "Family name between socio-cultural feature and genetic metaphor - From concepts to methods" was held in Paris on the 9th and 10th December 2010, partly sponsored by the Social Science and Humanity Institute (CNRS), and by Human Biology. This workshop was intended to facilitate exchanges on recent questions related to the names of persons and to confront different multidisciplinary approaches in a field of investigation where geneticists and historians, geographers, sociologists and ethnologists have all an active part. Here are the abstracts of some contributions.
Human Pelvis And Long Bones Reveal Differential Preservation Of Ancient Population History And Migration Out Of Africa, Lia Betti, Noreen Von Cramon-Taubadel, Stephen J. Lycett
Human Pelvis And Long Bones Reveal Differential Preservation Of Ancient Population History And Migration Out Of Africa, Lia Betti, Noreen Von Cramon-Taubadel, Stephen J. Lycett
Human Biology Open Access Pre-Prints
One of the main events in the history of our species has been our expansion out of Africa. A clear signature of this expansion has been found on global patterns of neutral genetic variation, whereby a serial founder effect accompanied the colonization of new regions, in turn creating a within-population decrease in neutral genetic diversity with increasing distance from Africa. This same distinctive pattern has also been described for cranial and dental morphological variation in human populations distributed across the globe. Here, we used a dataset of postcranial linear measurements for 30 globally distributed human populations, and a climatic dataset …
Cranial Variation And The Transition To Agriculture In Europe, Ron Pinhasi, Noreen Von Cramon-Taubadel
Cranial Variation And The Transition To Agriculture In Europe, Ron Pinhasi, Noreen Von Cramon-Taubadel
Human Biology Open Access Pre-Prints
Debates surrounding the nature of the Neolithic demographic transition in Europe have historically centred on two opposing models; a 'demic' diffusion model whereby incoming farmers from the Near East and Anatolia effectively replaced or completely assimilated indigenous Mesolithic foraging communities and an 'indigenist' model resting on the assumption that ideas relating to agriculture and animal domestication diffused from the Near East, but with little or no gene flow. The extreme versions of these dichotomous models have been heavily contested primarily on the basis of archaeological and modern genetic data. However, in recent years there has been a growing acceptance of …

Human Biology Open Access Pre-Prints
In order to verify the possibility that the Y-chromosome C3* star-cluster attributed to Genghis Khan and his patrilineal descendants is relatively frequent in the Kereys, who are the dominant clan in Kazakhstan and in Central Asia as a whole, polymorphism of the Y-chromosome was studied in Kazakhs, represented mostly by members of the Kerey clan. The Kereys showed the highest frequency (76.5%) of individuals carrying the Y-chromosome variant known as C3* star-cluster ascribed to the descendants of Genghis Khan. C3* star-cluster haplotypes were found in two sub-clans, Abakh-Kereys and Ashmaily-Kereys, diverged about 20-22 generations ago according to the historical data. …

Changing Language, Remaining Pygmy, Serge Bahuchet
Human Biology Open Access Pre-Prints
In this article I am illustrating the linguistic diversity of African Pygmy populations in order to better address their anthropological diversity and history. I am also introducing a new method, based on the analysis of specialized vocabulary, to reconstruct the substratum of some languages they speak. I show that Pygmy identity is not based on their languages, which have often been borrowed from neighboring non-Pygmy farmer communities with whom each Pygmy group is linked. Understanding the nature of this partnership, quite variable in history, is essential to address Pygmy languages, identity and history. Finally, I show that only a multidisciplinary …
