Ancient human movements through Asia DNA has allowed us to begin tracing the history of across globe. Narasimhan et al. identify a complex pattern migrations and admixture events in South Central by performing genetic analysis more than 500 people who lived over past 8000 years (see Perspective Schaefer Shapiro). They establish key phases population prehistory Eurasia, including spread farming peoples from Near East, with both westward eastward. The known as Yamnaya Bronze Age also moved...
Southeast Asia is home to rich human genetic and linguistic diversity, but the details of past population movements in region are not well known. Here, we report genome-wide ancient DNA data from 18 Asian individuals spanning Neolithic period through Iron Age (4100 1700 years ago). Early farmers Man Bac Vietnam exhibit a mixture East (southern Chinese agriculturalist) deeply diverged eastern Eurasian (hunter-gatherer) ancestry characteristic Austroasiatic speakers, with similar as far south...
By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe West Asia) over 10,000 years, we contextualize Chalcolithic period Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with Eurasian steppe. Two streams of migration transmitted Caucasus Anatolian/Levantine ancestry northward, Yamnaya pastoralists, formed on steppe, then spread southward into Balkans across Armenia, where they left numerous patrilineal...
Ancient DNA (aDNA) research involves invasive and destructive sampling procedures that are often incompatible with anthropological, anatomical, bioarcheological analyses requiring intact skeletal remains. The osseous labyrinth inside the petrous bone has been shown to yield higher amounts of endogenous than any other element; however, accessing this in cases a complete or reconstructed skull causing major structural damage cranial vault base. Here, we describe novel base drilling method...
Literary and archaeological sources have preserved a rich history of Southern Europe West Asia since the Bronze Age that can be complemented by genetics. Mycenaean period elites in Greece did not differ from general population included both people with some steppe ancestry others, like Griffin Warrior, without it. Similarly, central area Urartian Kingdom around Lake Van lacked characteristic kingdom's northern provinces. Anatolia exhibited extraordinary continuity down to Roman Byzantine...
Abstract The genetic formation of Central and South Asian populations has been unclear because an absence ancient DNA. To address this gap, we generated genome-wide data from 362 individuals, including the first eastern Iran, Turan (Uzbekistan, Turkmenistan, Tajikistan), Bronze Age Kazakhstan, Asia. Our reveal a complex set sources that ultimately combined to form ancestry Asians today. We document southward spread Eurasian Steppe, correlating with archaeologically known expansion...
We present the first ancient DNA data from Pre-Pottery Neolithic of Mesopotamia (Southeastern Turkey and Northern Iraq), Cyprus, Northwestern Zagros, along with Armenia. show that these neighboring populations were formed through admixture pre-Neolithic sources related to Anatolian, Caucasus, Levantine hunter-gatherers, forming a continuum ancestry mirroring geography West Asia. By analyzing Pottery Anatolia, we former derived between Mesopotamian-related local Epipaleolithic-related...
Human culture, biology, and health were shaped dramatically by the onset of agriculture ∼12,000 y B.P. This shift is hypothesized to have resulted in increased individual fitness population growth as evidenced archaeological genomic data alongside a decline physiological inferred from skeletal remains. Here, we consider osteological ancient DNA same prehistoric individuals study human stature variation proxy for across transition agriculture. Specifically, compared “predicted” genetic...
The impact of Late Pleistocene climatic oscillations, volcanism and the diverse terrain Armenian Highlands affected hominin population dynamics movements through region. To test different scenarios for period 50–25 ka regarding expansion, adaptive response, intra-population interactions extinction, we need local on-site paleoclimatic data found in association with occupations. However, this approach has been hampered by dearth highly uneven spatiotemporal recovery from prehistoric sites...
Tooth wear in primates is caused by aging and ecological factors. However, comparative data that would allow us to delineate the contribution of each these factors are lacking. Here, we contrast age-dependent molar tooth scoring percent dentine exposure (PDE) two wild African primate populations from Gabonese forest Kenyan savanna habitats. We found forest-dwelling mandrills exhibited significantly higher PDE with age than yellow baboons. Mandrills mainly feed on large tough food items, such...
Abstract Farming was first introduced to southeastern Europe in the mid-7 th millennium BCE – brought by migrants from Anatolia who settled region before spreading throughout Europe. To clarify dynamics of interaction between farmers and indigenous hunter-gatherers where they met, we analyze genome-wide ancient DNA data 223 individuals lived surrounding regions 12,000 500 BCE. We document previously uncharacterized genetic structure, showing a West-East cline ancestry hunter-gatherers, show...
The development of farming was a catalyst for the evolution human diet from varied subsistence practices hunter-gatherers to more globalised food economy we depend upon today. Although there has been considerable research into dietary changes associated with initial spread farming, less attention given how choices continued develop during subsequent millennia. A paleogenomic time transect 5 millennia occupation in Great Hungarian Plain spanning advent Neolithic Iron Age, showed major genomic...
Abstract Southeast Asia is home to rich human genetic and linguistic diversity, but the details of past population movements in region are not well known. Here, we report genome-wide ancient DNA data from thirteen Asian individuals spanning Neolithic period through Iron Age (4100–1700 years ago). Early agriculturalists Man Bac Vietnam possessed a mixture East (southern Chinese farmer) deeply diverged eastern Eurasian (hunter-gatherer) ancestry characteristic Austroasiatic speakers, with...
Morphometric variation of biological structures has been widely used to determine taxonomic affinities among taxa, and teeth are especially informative for both deep phylogenetic relationships specific ecological signals. We report 2-dimensional geometric morphometrics (GM) analyses occlusal crown surfaces lower molars (M 1 , n = 141; M 2 158) cercopithecoid primate species. A 12-landmark configuration, including cusp tips 8 points the molar contour, were evaluate patterns in shape primates...
We report genome-wide ancient DNA from 44 Near Easterners ranging in time between ~12,000-1,400 BCE, Natufian hunter-gatherers to Bronze Age farmers. show that the earliest populations of East derived around half their ancestry a ‘Basal Eurasian’ lineage had little if any Neanderthal admixture and separated other non-African lineages prior separation each other. The first farmers southern Levant (Israel Jordan) Zagros Mountains (Iran) were strongly genetically differentiated, descended local...
Abstract Dietary reconstruction is used to make inferences about the subsistence strategies of ancient human populations, but it may also serve as a proxy characterise their diverse cultural and technological manifestations. Dental microwear stable isotope analyses have been shown be successful techniques for paleodietary populations but, despite yielding complementary dietary information, these rarely combined within same study. Here we present first time comprehensive approach interpreting...
Abstract Human culture, biology, and health were shaped dramatically by the onset of agriculture ~12,000 years before present (BP). Subsistence shifts from hunting gathering to are hypothesized have resulted in increased individual fitness population growth as evidenced archaeological genomic data alongside a simultaneous decline physiological inferred paleopathological analyses stature reconstructions skeletal remains. A key component inference is that relatively shorter statures observed...
A series of studies have documented how Steppe pastoralist-related ancestry reached central Europe by at least 2500 BCE, while Iranian farmer-related was present in Aegean 1900 BCE. However, the spread these ancestries into western Mediterranean where they contributed to many populations living today remains poorly understood. We generated genome-wide ancient DNA from Balearic Islands, Sicily, and Sardinia, increasing number individuals with reported data islands 3 52. obtained oldest...
