After Very long period of Waiting for an ancient R1a-M458 specimen. the First Pre Medieval R1a-M458 probably have been found! Coming from Bronze Age Switzerland/Southwestern Germany. The Specimen MX265 comes from the Data set of yet unpublished thesis named: "Genetic transition in the Swiss Late Neolithic and Early Bronze Age" associated with this abstract: https://boris.unibe.ch/133227/. MX265 has calls to three SNPs: PF6155 level: AM01874+ A>G (1 read); AM01875+ C>A (1 read); PF6161+ C>T (1 read)
PF6155>M458 level: PF6202+ T>C (3 reads).

In Europe the characterization of the Neolithic period is traditionally dominated by the advent of agro-pastoralism. Neolithic populations in the Dnieper Valley region of south-central Ukraine are notably divergent from this trend. From the Epi-Palaeolithic-Neolithic periods (ca. 10,000 - 6000 cal BC), evidence for the adoption of agro-pastoral technologies is absent from archaeological assemblages. It is not until the Eneolithic period (ca. 4500 cal BC) that we observe the beginnings of a transition to farming in the Dnieper region. One hypothesis suggests that spikes in aridity propagated a hunting crisis in Mesolithic populations, which prompted a delay in the transition and the reshaped of Mesolithic subsistence practices to focus on freshwater aquatic resources to supplement terrestrial herbivores such as boar and deer.
This research presents 300+ human and faunal samples (including 80 unpublished results), using multi-disciplinary techniques such as DNA analysis and various isotope applications, alongside osteological analysis, to provide holistic individual life histories. The results show long-term continuation of fishing practices from the Epi-Palaeolithic to Neolithic periods - no distinct shift from hunting to fishing practices took place. DNA results show the predominance of indigenous hunter-gatherers, with limited genetic inclusions from proximal Anatolian farming populations. Thus, despite the availability of plentiful dietary resources and the westward influence of extra-local farming populations, the prehistoric communities of the Dnieper region remained resistant to change and resilient in terms of their subsistence strategies, with freshwater resources providing a ‘buffer’ against any perceived impacts from climate variability.

Recent ancient-DNA studies have described substantial gene flow from Bronze-Age populations of the Eurasian steppe, with likely connections to the spread of Indo-European languages. The origins of these people and their later dispersals to the northwestern end of Eurasian steppe zone remain less understood. In northeastern Europe, the Neolithic and Eneolithic (Chalcolithic) periods witnessed the transition of subsistence strategies from the foraging lifestyle into pastoralism. These changes both caused and encouraged large-scale environmental modifications and substantiated divisions between boreal forests, temperate grasslands, and the intermediate belt of forest-steppe. Whether the genetics and evolution of local languages of human populations reflect these environmental zones, is yet largely to be explored.
Here we target the population-genetic transition processes through genome-wide next-generation sequencing data of 25 Eneolithic to Bronze-Age individuals from seven archaeological sites in southwestern Russia. We observe a consistent signal of the hunter-gatherer -like ancestries, followed by the earliest occurrences of individuals with Iranian Neolithic-related ancestry (previously described as ‘steppe ancestry’) mixed with these.
In addition, remnants of the genetic ancestry from early Siberian populations, today mainly prevalent in the Native Americans, are present in the region.
These results provide novel insight to an integral contact zone between major cultural movements, illuminating the role of the forest-steppe populations in Eurasian prehistory and their early contacts with the Eurasian agro-pastoralists.
Furthermore, the waves of cultural and genetic input may have heralded language exchange between the early forms or predecessors of Uralic languages, with the Indo-European effects still observed in their modern equivalents.

Central Asia was a hub of economic and cultural interaction that flowed along the Silk Roads - vast overland trade networks that linked East Asia, the Middle East and Europe. During the Medieval period (ca. 2nd-16th c. CE) these networks famously facilitated the trade of material items, such as glazed pottery and lapis lazuli, which can be found in the archaeological record. However, little is directly known about the people who lived along the Silk Roads and how this vast interconnected network directly influenced diet, health and day-to-day living.
This paper presents the results of one of the first comprehensive bioarchaeological investigations focused on Medieval and other cemeteries in southwest Uzbekistan, including a possible double soldier burial that may be associated with the Hellenistic Period in the region (late 4th and 3rd c. BC). Individuals interred in two cemeteries (Bobolangar and Tell Garden) dating to the High Medieval Period (1000-1150 CE) and one later cemetery (Lungi Tepa) display a high prevalence of systemic disease, trauma and a large variation in body size. The aim of this research is to understand how people adapted to the harsh desert environment, procured their food, interacted with surrounding communities and cared for their sick and disabled in the context of the first globalised trade network. The research uses a biocultural approach that incorporates traditional osteological methods, ancient DNA and isotope analyses. These results are interpreted within current theoretical frameworks in Anthropology, including Niche Construction Theory and the Bioarchaeology of Care Model.

The Bronze Age in Eurasia was a period of intense human mobility that transformed the genomic landscape of this entire region. In recent years, metagenomic analyses of human remains dating between 5,000 and 3,500 years before present (BP) revealed a number of human-associated pathogens that accompanied and potentially influenced these population movements. One such example is the plague-bacterium, Yersinia pestis. Previous studies have shown that Late Neolithic and Early Bronze Age (LNBA) Y. pestis genomes formed a putatively extinct phylogenetic lineage that paralleled human mobility across Eurasia. Here, we present the metagenomic screening of Neolithic and Bronze Age remains from the Lake Baikal region in Siberia and show the presence of Y. pestis infections in two individuals.
Subsequent whole-genome enrichment and comparison against a panel of ancient and modern-day Y. pestis genomes revealed their analogous phylogenetic placement and genomic contents to published LNBA isolates from Europe and Central Asia. Their further analysis alongside newly generated human genome-wide and isotopic data shows high mobility within Siberia during the Bronze Age, through the identification of genomic outliers. Moreover, we present a novel age estimation approach, using molecular dating of bacterial genomes, and show a large offset in the radiocarbon dates of Y. pestis-positive individuals, likely influenced by a regional freshwater reservoir effect. Collectively, our results suggest that Y. pestis spread into the Lake Baikal region within the context of human expansions across the Eurasian steppe during the 5th millennium BP, also affecting individuals whose genomic makeup was not impacted by such migrations.

Description

Genomic studies conducted on ancient individuals across Europe have unraveled how migrations have contributed to its present genetic landscape, but the territory of present-day France has yet to be connected to the broader European picture. We generated a large dataset comprising the complete mitochondrial genomes, Y chromosome markers and genotypes on a number of nuclear loci of interest, obtained through a DNA enrichment approach, of 203 individuals sampled across present-day France over a period spanning 7,000 years, complemented with a partially overlapping dataset of 58 low-coverage genomes. This panel provides, for the first time, a high-resolution transect of the dynamics of maternal and paternal lineages in France as well as of autosomal genotypes. Both parental lineages and genomic data revealed demographic patterns in France for the Neolithic and Bronze Age transition consistent with neighboring regions with a first wave of migration of Anatolian farmers, then varying degrees of admixture with autochthonous hunter-gatherers and a second high gene flow from individuals deriving part of their ancestry from the Pontic Steppe at the onset of the Bronze Age. Our data have also highlighted the persistence of the Magdalenian heritage in hunter-gatherer populations outside Spain and thus provide arguments for an expansion of these populations at the end of the Paleolithic period, more northerly than what has been described so far. Finally, no major demographic changes were detected during the transition between the Bronze and Iron Ages.

A Paleogenomic Reconstruction of the Deep Population History of the Andes

Highlights

• Ancient DNA transect reveals north-south substructure of Andean highlands by 5,800 BP
• After 5,800 BP, gene flow mixed highland people with their neighbors
• After 2,000 BP, striking genetic continuity through rise and fall of major cultures

Summary

There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus on the period of the rise and fall of state societies. Today’s genetic structure began to develop by 5,800 BP, followed by bi-directional gene flow between the North and South Highlands, and between the Highlands and Coast. We detect minimal admixture among neighboring groups between ∼2,000–500 BP, although we do detect cosmopolitanism (people of diverse ancestries living side-by-side) in the heartlands of the Tiwanaku and Inca polities. We also highlight cases of long-range mobility connecting the Andes to Argentina and the Northwest Andes to the Amazon Basin.

При исследовании пещеры Бачо Киро в Болгарии были обнаружены остатки костей человека. Радиоуглеродное датирование показало возраст в 45 000 лет. Пока проанализировали только митохондриальную ДНК, но лаборатория Паабо сейчас пытается получить полный геном. Из анализа ДНК ясно что это сапиенсы. Так что это на данный момент древнейшие останки Homo Sapiens в Европе.
