Tuberculosis in prehistory in Eastern Central Europe (Hungary) - Chronological and geographical distribution.

Tuberculosis (TB) has long been a major scourge of humankind. Paleopathological and paleomicrobiological studies have revealed the past presence of the disease on a large spatial and temporal scale. The antiquity of the disease has extensively been studied in the Carpathian Basin, given its dynamic population and cultural changes since prehistory. These studies, however, have mainly focused on the populations living during the Common Era. The aim of this paper is to present the published and the recently discovered cases of prehistoric TB, from the Neolithic (6000-4500/4400 BCE) to the Bronze Age (2600/2500-800 BCE) Central Carpathian Basin (Hungary). We summarize 18 published cases and present new cases dating to the Neolithic period and introduce 3 newly discovered Bronze Age cases of TB. Despite extensive research, TB has not yet been identified from the Copper and Iron Ages in the Carpathian Basin. Considering the state of TB research, and supplemented by our prehistoric dataset, the spatio-temporal pattern of the disease can be further elucidated, thus advancing future molecular and paleopathological studies. Our dataset offers comprehensive spatial and temporal information on the spread of the disease in the Carpathian Basin, along with a detailed biological profile of the demonstrated cases and extensive paleopathological descriptions of the observed lesions, complemented by photographic evidence. This invaluable resource paves the way for enhanced understanding and progress in the field.

Interdisciplinary Analyses of Bronze Age Communities from Western Hungary Reveal Complex Population Histories.

In this study, we report 21 ancient shotgun genomes from present-day Western Hungary, from previously understudied Late Copper Age Baden, and Bronze Age Somogyvár-Vinkovci, Kisapostag, and Encrusted Pottery archeological cultures (3,530-1,620 cal Bce). Our results indicate the presence of high steppe ancestry in the Somogyvár-Vinkovci culture. They were then replaced by the Kisapostag group, who exhibit an outstandingly high (up to ∼47%) Mesolithic hunter-gatherer ancestry, despite this component being thought to be highly diluted by the time of the Early Bronze Age. The Kisapostag population contributed the genetic basis for the succeeding community of the Encrusted Pottery culture. We also found an elevated hunter-gatherer component in a local Baden culture-associated individual, but no connections were proven to the Bronze Age individuals. The hunter-gatherer ancestry in Kisapostag is likely derived from two main sources, one from a Funnelbeaker or Globular Amphora culture-related population and one from a previously unrecognized source in Eastern Europe. We show that this ancestry not only appeared in various groups in Bronze Age Central Europe but also made contributions to Baltic populations. The social structure of Kisapostag and Encrusted Pottery cultures is patrilocal, similarly to most contemporaneous groups. Furthermore, we developed new methods and method standards for computational analyses of ancient DNA, implemented to our newly developed and freely available bioinformatic package. By analyzing clinical traits, we found carriers of aneuploidy and inheritable genetic diseases. Finally, based on genetic and anthropological data, we present here the first female facial reconstruction from the Bronze Age Carpathian Basin.

An integrative skeletal and paleogenomic analysis of stature variation suggests relatively reduced health for early European farmers.

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 and population growth as evidenced by archaeological and population genomic data alongside a decline in physiological health as inferred from skeletal remains. Here, we consider osteological and ancient DNA data from the same prehistoric individuals to study human stature variation as a proxy for health across a transition to agriculture. Specifically, we compared "predicted" genetic contributions to height from paleogenomic data and "achieved" adult osteological height estimated from long bone measurements for 167 individuals across Europe spanning the Upper Paleolithic to Iron Age (∼38,000 to 2,400 B.P.). We found that individuals from the Neolithic were shorter than expected (given their individual polygenic height scores) by an average of −3.82 cm relative to individuals from the Upper Paleolithic and Mesolithic (P = 0.040) and −2.21 cm shorter relative to post-Neolithic individuals (P = 0.068), with osteological vs. expected stature steadily increasing across the Copper (+1.95 cm relative to the Neolithic), Bronze (+2.70 cm), and Iron (+3.27 cm) Ages. These results were attenuated when we additionally accounted for genome-wide genetic ancestry variation: for example, with Neolithic individuals −2.82 cm shorter than expected on average relative to pre-Neolithic individuals (P = 0.120). We also incorporated observations of paleopathological indicators of nonspecific stress that can persist from childhood to adulthood in skeletal remains into our model. Overall, our work highlights the potential of integrating disparate datasets to explore proxies of health in prehistory.

Parallel palaeogenomic transects reveal complex genetic history of early European farmers.

Ancient DNA studies have established that Neolithic European populations were descended from Anatolian migrants who received a limited amount of admixture from resident hunter-gatherers. Many open questions remain, however, about the spatial and temporal dynamics of population interactions and admixture during the Neolithic period. Here we investigate the population dynamics of Neolithization across Europe using a high-resolution genome-wide ancient DNA dataset with a total of 180 samples, of which 130 are newly reported here, from the Neolithic and Chalcolithic periods of Hungary (6000-2900 bc, n = 100), Germany (5500-3000 bc, n = 42) and Spain (5500-2200 bc, n = 38). We find that genetic diversity was shaped predominantly by local processes, with varied sources and proportions of hunter-gatherer ancestry among the three regions and through time. Admixture between groups with different ancestry profiles was pervasive and resulted in observable population transformation across almost all cultural transitions. Our results shed new light on the ways in which gene flow reshaped European populations throughout the Neolithic period and demonstrate the potential of time-series-based sampling and modelling approaches to elucidate multiple dimensions of historical population interactions.

Possible cases of leprosy from the Late Copper Age (3780-3650 cal BC) in Hungary.

At the Abony-Turjányos dulo site, located in Central Hungary, a rescue excavation was carried out. More than 400 features were excavated and dated to the Protoboleráz horizon, at the beginning of the Late Copper Age in the Carpathian Basin, between 3780-3650 cal BC. Besides the domestic and economic units, there were two special areas, with nine-nine pits that differed from the other archaeological features of the site. In the northern pit group seven pits contained human remains belonging to 48 individuals. Some of them were buried carefully, while others were thrown into the pits. The aim of this study is to present the results of the paleopathological and molecular analysis of human remains from this Late Copper Age site. The ratio of neonates to adults was high, 33.3%. Examination of the skeletons revealed a large number of pathological cases, enabling reconstruction of the health profile of the buried individuals. Based on the appearance and frequency of healed ante- and peri mortem trauma, inter-personal (intra-group) violence was characteristic in the Abony Late Copper Age population. However other traces of paleopathology were observed on the bones that appear not to have been caused by warfare or inter-group violence. The remains of one individual demonstrated a rare set of bone lesions that indicate the possible presence of leprosy (Hansen's disease). The most characteristic lesions occurred on the bones of the face, including erosion of the nasal aperture, atrophy of the anterior nasal spine, inflammation of the nasal bone and porosity on both the maxilla and the bones of the lower legs. In a further four cases, leprosy infection is suspected but other infections cannot be excluded. The morphologically diagnosed possible leprosy case significantly modifies our knowledge about the timescale and geographic spread of this specific infectious disease. However, it is not possible to determine the potential connections between the cases of possible leprosy and the special burial circumstances.

Tuberculosis in Late Neolithic-Early Copper Age human skeletal remains from Hungary.

Alsónyék-Bátaszék in Southern Hungary is one of the largest late Neolithic settlements and cemeteries excavated in Central Europe. In total, 2359 burials from the Late Neolithic - Early Copper Age Lengyel culture were found between 2006 and 2009 [1]. Anthropological investigations previously carried out on individuals from this site revealed an interesting paleopathological case of tuberculosis in the form of Pott's disease dated to the early 5(th) millennium BC. In this study, selected specimens from this osteoarcheological series were subjected to paleomicrobiological analysis to establish the presence of MTBC bacteria. As all individuals showing clear osteological signs of TB infection belonged to a single grave group, 38 individuals from this grave group were analysed. The sample included the case of Pott's disease as well as individuals both with and without osseous TB manifestations. The detection of TB DNA in the individual with Pott's disease provided further evidence for the occurrence of TB in Neolithic populations of Europe. Moreover, our molecular analysis indicated that several other individuals of the same grave group were also infected with TB, opening the possibility for further analyses of this unique Neolithic skeletal series.
