Exploration de l'architecture génétique et des facteurs environnementaux influençant la diversité pigmentaire de la peau en Papouasie-Nouvelle-Guinée
La pigmentation de la peau est un trait complexe et hautement variable chez les humains. Il est influencé par une multitude de facteurs tels que le rayonnement ultra-violet, l’alimentation, le mode de vie, la sélection sexuelle et l’introgression avec des humains archaïques. La Papouasie-Nouvelle-Guinée (PNG), réputée pour sa diversité biologique et culturelle exceptionnelle, présente une large gamme de variations de pigmentation de la peau. Cett…
Hand stencils and communal history: A case study from Auwim, East Sepik, Papua New Guinea
Hand stencils directly represent modern humans in landscape settings around the world. Yet their social and cultural contexts are often overlooked due to the lack of ethnography associated with the artwork. This paper explores the hand stencils from Kundumbue and Pundimbung rock art sites, situated in the traditional boundaries of the Auwim people in the East Sepik Province of Papua New Guinea. Combining archaeological rock art analysis with ethn…
Mainland-coastal interactions in East Borneo: Inter-site comparison and Bayesian chronological models of two Late Pleistocene–Holocene sequences (Liang Abu and Kimanis rock shelters)
In recent decades, East Borneo has become an increasingly important archaeological “hot-spot” in Island Southeast Asia as a result of early dates for rock art ca. 38,000 BP and the greater number of excavated sites that support a much longer period of human occupation. However, the chronology of settlement and adaptation to environmental changes during the Pleistocene–Holocene transition is still poorly known. Here we report on an excavation at t…
Rock Art and (Re)Production of Narratives: A Cassowary Bone Dagger Stencil Perspective from Auwim, East Sepik, Papua New Guinea
Cassowaries (Casuarius) are one of the largest indigenous animal species of New Guinea. Researchers have long been trying to understand their local socio-cultural significance. Here we present new results from interviews recorded in 2018 on ethnography associated with bone daggers, a material culture ornament and tool carved from the cassowary's tibiotarsus. We present a ‘storied notion’—a contemporary narrative from oral history of why cassowary…
Rock art and long-distance prehistoric exchange behavior: A case study from Auwim, East Sepik, Papua New Guinea
Since 1909, patrol officers, anthropologists, archaeologists, and others have identified evidence of a pre-contact trading network linking New Guinea with the Torres Strait. Current research in the Lower Sepik River Basin reported various ethnographic descriptions relating to cultural material objects stenciled on various rock art sites in Auwim, Upper Karawari-Arafundi region, East Sepik, Papua New Guinea (PNG). In addition to the rock art, the …
Sahelian pastoralism from the perspective of variants associated with lactase persistence
OBJECTIVES: Archeological evidence shows that first nomadic pastoralists came to the African Sahel from northeastern Sahara, where milking is reported by ~7.5 ka. A second wave of pastoralists arrived with the expansion of Arabic tribes in 7th-14th century CE. All Sahelian pastoralists depend on milk production but genetic diversity underlying their lactase persistence (LP) is poorly understood. MATERIALS AND METHODS: We investigated SNP variants…
Genomic insights into the peopling of the Southwest Pacific
A genomic history of Aboriginal Australia
The population history of Aboriginal Australians remains largely uncharacterized. Here we generate high-coverage genomes for 83 Aboriginal Australians (speakers of Pama–Nyungan languages) and 25 Papuans from the New Guinea Highlands. We find that Papuan and Aboriginal Australian ancestors diversified 25–40 thousand years ago (kya), suggesting pre-Holocene population structure in the ancient continent of Sahul (Australia, New Guinea and Tasmania).…

Genomic evidence for the Pleistocene and recent population history of Native Americans
Genetic history of Native Americans Several theories have been put forth as to the origin and timing of when Native American ancestors entered the Americas. To clarify this controversy, Raghavan et al. examined the genomic variation among ancient and modern individuals from Asia and the Americas. There is no evidence for multiple waves of entry or recurrent gene flow with Asians in northern populations. The earliest migrations occurred no earlier…
Pig Domestication and Human-Mediated Dispersal in Western Eurasia Revealed through Ancient DNA and Geometric Morphometrics
Zooarcheological evidence suggests that pigs were domesticated in Southwest Asia ~8,500 BC. They then spread across the Middle and Near East and westward into Europe alongside early agriculturalists. European pigs were either domesticated independently or more likely appeared so as a result of admixture between introduced pigs and European wild boar. As a result, European wild boar mtDNA lineages replaced Near Eastern/Anatolian mtDNA signatures i…
A Time Series of Prehistoric Mitochondrial DNA Reveals Western European Genetic Diversity Was Largely Established by the Bronze Age
A major unanswered question concerns the roles of continuity versus change in prehistoric Europe. For the first time, genetic samples of reasonable size taken at multiple time points are revealing piecemeal snapshots of European prehistory at different dates and places across the continent. Here, we pull these disparate datasets together to illustrate how human genetic variation has changed spatially and temporally in Europe from the Mesolithic t…
An Aboriginal Australian Genome Reveals Separate Human Dispersals into Asia
Whole-genome data indicate that early modern humans expanded into Australia 62,000 to 75,000 years ago.
Prehistoric occupation at the rock shelter of Liang Abu, eastern Borneo
MtDNA variation in the Buryat population of the Barguzin Valley: New insights into the micro-evolutionary history of the Baikal area
These results underline the need to use local samples, in addition to pooled samples, to investigate the history of human populations at the micro-evolutionary level
Comparison between morphological and genetic data to estimate biological relationship: The case of the Egyin Gol necropolis (Mongolia)
Osseous and dental nonmetric (discrete) traits have long been used to assess population variability and affinity in anthropological and archaeological contexts. However, the full extent to which nonmetric traits can reliably be used as a proxy for genetic data when assessing close or familial relationships is currently poorly understood. This study represents the unique opportunity to directly compare genetic and nonmetric data for the same indiv…
Ancient Solomon Islands mtDNA: Assessing Holocene settlement and the impact of European contact
Cranial Discrete Traits in a Byzantine Population and Eastern Mediterranean Population Movements
Since the beginning of the Holocene, the Anatolian region has been a crossroads for populations and civilizations from Europe, Asia, and the Near to Middle East, with increasing interactions since the Bronze Age. In this context, we examine cranial discrete traits from a Byzantine population from southwest Turkey, excavated at the archeological site of Sagalassos; the site displays human occupation since the 12th millennium b.p. To investigate th…

Ancient mitochondrial DNA from Malaysian hair samples: Some indications of Southeast Asian population movements
The late Pleistocene and early Holocene population history of Southeast Asia is not well‐known. Our study provides new data on mitochondrial DNA (mtDNA) lineages of the aboriginal inhabitants of the Malay Peninsula, and through an extensive comparison to the known mtDNA diversity in Southeast and East Asia, provides some new insights into the origins and historical geography of certain mtDNA lineages in the region. We extracted DNA from hair samp…
Molecular Genetic Analysis of 400-Year-Old Human Remains Found in Two Yakut Burial Sites
The excavation of five frozen graves at the Sytygane Syhe and Istekh-Myrane burial sites (dated at 400 years old) in central Yakutia revealed five human skeletons belonging to the Yakut population. To investigate the origin and evolution of the Yakut population as well as the kinship system between individuals buried in these two sites, DNA was extracted from bone samples and analyzed by autosomal short tandem repeats (STRs) and by sequencing hyp…
Inhumation and cremation in medieval Mongolia: Analysis and Analogy
The authors study burials of the medieval period in western Mongolia shortly before emergence of Genghis Khan. They find that both inhumation and cremation are practised, with a variety of accompanying rituals. Systematic micro-analysis of bone fragments on the one hand, and the accounts of early travellers on the other, allow these researchers to propose detailed explanations of mortuary practice in thirteenth century Altai that will be highly s…

Genetic analysis and ethnic affinities from two Scytho‐Siberian skeletons
We extracted DNA from two skeletons belonging to the Sytho‐Siberian population, which were excavated from the Sebÿstei site (dating back 2,500 years) in the Altai Republic (Central Asia). Ancient DNA was analyzed by autosomal short tandem repeats (STRs) and by the sequencing of the hypervariable region 1 (HV1) of the mitochondrial DNA (mtDNA) control region. The results showed that these two skeletons were not close relatives. Moreover, their hap…

Genetic Analysis of a Scytho-Siberian Skeleton and Its Implications for Ancient Central Asian Migrations
The excavation of a frozen grave on the Kizil site (dated to be 2500 years old) in the Altai Republic (Central Asia) revealed a skeleton belonging to the Scytho-Siberian population. DNA was extracted from a bone sample and analyzed by autosomal STRs (short tandem repeats) and by sequencing the hypervariable region I (HV1) of the mitochondrial DNA. The resulting STR profile, mitochondrial haplotype, and haplogroup were compared with data from mode…
Ancient DNA analysis of human neolithic remains found in northeastern Siberia: Genetic Analysis of A Neolithic Siberian
We successfully extracted DNA from a bone sample of a Neolithic skeleton (dated 3,600 +/- 60 years BP) excavated in northeastern Yakutia (east Siberia). Ancient DNA was analyzed by autosomal STRs (short tandem repeats) and by sequencing of the hypervariable region I (HV1) of the mitochondrial DNA (mtDNA) control region. The STR profile, the mitochondrial haplotype, and the haplogroup determined were compared with those of modern Eurasian and Nati…
