RESUMEN
The Yamnaya archaeological complex appeared around 3300BCE across the steppes north of the Black and Caspian Seas, and by 3000BCE reached its maximal extent from Hungary in the west to Kazakhstan in the east. To localize the ancestral and geographical origins of the Yamnaya among the diverse Eneolithic people that preceded them, we studied ancient DNA data from 428 individuals of which 299 are reported for the first time, demonstrating three previously unknown Eneolithic genetic clines. First, a "Caucasus-Lower Volga" (CLV) Cline suffused with Caucasus hunter-gatherer (CHG) ancestry extended between a Caucasus Neolithic southern end in Neolithic Armenia, and a steppe northern end in Berezhnovka in the Lower Volga. Bidirectional gene flow across the CLV cline created admixed intermediate populations in both the north Caucasus, such as the Maikop people, and on the steppe, such as those at the site of Remontnoye north of the Manych depression. CLV people also helped form two major riverine clines by admixing with distinct groups of European hunter-gatherers. A "Volga Cline" was formed as Lower Volga people mixed with upriver populations that had more Eastern hunter-gatherer (EHG) ancestry, creating genetically hyper-variable populations as at Khvalynsk in the Middle Volga. A "Dnipro Cline" was formed as CLV people bearing both Caucasus Neolithic and Lower Volga ancestry moved west and acquired Ukraine Neolithic hunter-gatherer (UNHG) ancestry to establish the population of the Serednii Stih culture from which the direct ancestors of the Yamnaya themselves were formed around 4000BCE. This population grew rapidly after 3750-3350BCE, precipitating the expansion of people of the Yamnaya culture who totally displaced previous groups on the Volga and further east, while admixing with more sedentary groups in the west. CLV cline people with Lower Volga ancestry contributed four fifths of the ancestry of the Yamnaya, but also, entering Anatolia from the east, contributed at least a tenth of the ancestry of Bronze Age Central Anatolians, where the Hittite language, related to the Indo-European languages spread by the Yamnaya, was spoken. We thus propose that the final unity of the speakers of the "Proto-Indo-Anatolian" ancestral language of both Anatolian and Indo-European languages can be traced to CLV cline people sometime between 4400-4000 BCE.
RESUMEN
The causative agent of tuberculosis is still a widespread pathogen, which caused the death of ca. 1.6 million people globally in 2021. The paleopathological study of human remains revealed the antiquity of the disease and its continuous presence throughout the history of humankind. The Carpathian Basin has always been a biocultural melting pot, since it has seen several migrations over the centuries, and served as a location of admixture and interaction for numerous populations of different cultures. Thus, this geographical territory is ideal for the examination of the coevolutionary processes of hosts and their pathogens. We aimed to reveal the spatial and temporal distribution of tuberculosis cases excavated inside the borders of Hungary between the 2nd and 16th centuries CE. We established a comprehensive database by collecting 114 already published cases and introducing 39 new cases. The involved cases include those that have been confirmed by different molecular methods, as well as possible infections that were identified based on the presence of macromorphological and radiological alterations. The progress of future molecular and paleopathological studies can be facilitated by our dataset, as it presents spatial and temporal information concerning the spread of the disease in the Carpathian Basin, as well as the biological profile and detailed paleopathological description of lesions illustrated by photo- and radiographs.

As the collapse of the Western Roman Empire accelerated during the 4th and 5th centuries, arriving "barbarian" groups began to establish new communities in the border provinces of the declining (and eventually former) empire. This was a time of significant cultural and political change throughout not only these border regions but Europe as a whole.1,2 To better understand post-Roman community formation in one of these key frontier zones after the collapse of the Hunnic movement, we generated new paleogenomic data for a set of 38 burials from a time series of three 5th century cemeteries3,4,5 at Lake Balaton, Hungary. We utilized a comprehensive sampling approach to characterize these cemeteries along with data from 38 additional burials from a previously published mid-6th century site6 and analyzed them alongside data from over 550 penecontemporaneous individuals.7,8,9,10,11,12,13,14,15,16,17,18,19 The range of genetic diversity in all four of these local burial communities is extensive and wider ranging than penecontemporaneous Europeans sequenced to date. Despite many commonalities in burial customs and demography, we find that there were substantial differences in genetic ancestry between the sites. We detect evidence of northern European gene flow into the Lake Balaton region. Additionally, we observe a statistically significant association between dress artifacts and genetic ancestry among 5th century genetically female burials. Our analysis shows that the formation of early Medieval communities was a multifarious process even at a local level, consisting of genetically heterogeneous groups.

The Scythians were a multitude of horse-warrior nomad cultures dwelling in the Eurasian steppe during the first millennium BCE. Because of the lack of first-hand written records, little is known about the origins and relations among the different cultures. To address these questions, we produced genome-wide data for 111 ancient individuals retrieved from 39 archaeological sites from the first millennia BCE and CE across the Central Asian Steppe. We uncovered major admixture events in the Late Bronze Age forming the genetic substratum for two main Iron Age gene-pools emerging around the Altai and the Urals respectively. Their demise was mirrored by new genetic turnovers, linked to the spread of the eastern nomad empires in the first centuries CE. Compared to the high genetic heterogeneity of the past, the homogenization of the present-day Kazakhs gene pool is notable, likely a result of 400 years of strict exogamous social rules.
RESUMEN
DNA recovery from ancient human remains has revolutionized our ability to reconstruct the genetic landscape of the past. Ancient DNA research has benefited from the identification of skeletal elements, such as the cochlear part of the osseous inner ear, that provides optimal contexts for DNA preservation; however, the rich genetic information obtained from the cochlea must be counterbalanced against the loss of morphological information caused by its sampling. Motivated by similarities in developmental processes and histological properties between the cochlea and auditory ossicles, we evaluate the ossicles as an alternative source of ancient DNA. We show that ossicles perform comparably to the cochlea in terms of DNA recovery, finding no substantial reduction in data quantity and minimal differences in data quality across preservation conditions. Ossicles can be sampled from intact skulls or disarticulated petrous bones without damage to surrounding bone, and we argue that they should be used when available to reduce damage to human remains. Our results identify another optimal skeletal element for ancient DNA analysis and add to a growing toolkit of sampling methods that help to better preserve skeletal remains for future research while maximizing the likelihood that ancient DNA analysis will produce useable results.

OBJECTIVE: The prevalence of hyperostosis frontalis interna (HFI) was examined in different periods of the Carpathian Basin from 4900 BCE to 17th century AD. The study seeks to evaluate temporal changes in HFI and the possible impact of lifestyle on it. MATERIALS: The studied material consisted of 4668 crania from Hungary and Serbia. METHODS: The crania were analyzed employing macroscopic and endoscopic examination. RESULTS: In historic periods, sex and age played a pivotal role in HFI development. Among predominantly pastoralist populations of the 5th-8th and 10th centuries, prevalence of HFI was considerably higher than in the medieval populations of the 9th-17th centuries. CONCLUSIONS: In addition to age and sex, other factors could be implicated in HFI development. The physiological effects of the pastoralist lifestyle and diet on insulin regulation could explain the increased risk of developing HFI in the 5th-8th and 10th-century populations. SIGNIFICANCE: The study provides the first comprehensive dataset of HFI from different archaeological periods from the Carpathian Basin. It has implications for lifestyle and risk of HFI development in past populations. LIMITATIONS: The archaeological periods are not equally represented. SUGGESTIONS FOR FURTHER RESEARCH: In order to better understand the etiology of HFI, lifestyle factors can be used to elucidate the risk of developing HFI in ancient populations.

BACKGROUND AND PURPOSE: Introducing the multidisciplinary paleoradiology research at the Institute of Diagnostic Imaging and Radiation Oncology of the Kaposvár University, highlighting the cases with potential central nervous system involvement--from the scanning methods to the 3D printing--in order to draw attention to the historical background and clinical aspects of certain pathological conditions. METHODS: The authors developed the examination protocols for three different CT scanners. Among the examined archaeological remains cranial lesions were identified in 26 cases, from which 4 cases with potential central nervous system involvement are demonstrated. The scanning parameters and the advantages of secondary image reconstructions (multiplanar reconstruction, maximum intensity projection, three-dimensional volume rendering technique) are presented with the cases. RESULTS: The authors demonstrate a case with destructive skull lesions due to syphilis from the 15th century AD, a condition rarely seen or even unknown nowadays in the modern world. With the CT images of the skull base fracture from the Iron Age, signs of healing could be verified. Using the CT images a non-invasive approach is presented in the case of the craniofacial osteosarcoma in order to visualize the local status and the direct intracranial propagation. Advantages of the 3D VRT reconstructions are shown in the case of unilateral coronal suture synostosis. CONCLUSION: Paleoradiological CT examinations serve as a non-invasive, non-destructive tool for studying archaeological remains and artifacts. The special applications provided by the imaging modality contribute to the conventional paleopathological investigations.

A unique single suture craniosynostosis case from the 9(th) century is presented in this paper. Although craniosynostosis is a fairly common pediatric anomaly nowadays, its occurrence in archaeological collections is an uncommon precedent. Since the diagnosis and treatment of premature cranial suture closure usually happens at an early age, evaluation of the whole developmental process is a rare opportunity. The right-sided coronal suture synostosis of this 30-35 years old woman gives an interesting opportunity to observe the effect of this phenomenon in adulthood. Only slight distortion of the viscerocranium and no bony signs of elevated intracranial pressure can be seen on the skull. The women suffered remarkable bending of the whole face and cranial base of the midsagittal plane. Besides the aesthetic disorder, the condition might have contributed to a chronic headache and visual disturbances. The lack of any other typical symptom suggests the diagnosis of isolated craniosynostosis or a milder type of syndromic craniosynostosis, the possibility of an underlying causative mutation cannot be ruled out.

SUMMARY: The Zalavár-Chapel (Hungarian: Zalavár-Kápolna) cemetery was found near the village Zalavár, located in the western part of the Lake Balaton, in the area of the Little-Balaton (in Hungarian: Kis-Balaton) in Hungary. Burial around the chapel started in the second half of the 11th century and was finished in the 13th century. During this period, significant changes occurred in the burial customs, thus the graves can be divided into four groups (horizons) chronologically. The first horizon includes the earliest, while the third and fourth the latest burials. Earlier, it was assumed that the differences in the burial customs were signs of population changes in that area. However, based on the results of our examination, it was used most probably by the same population throughout the whole time. The craniometric comparison of the skeletons of the Zalavár-Chapel cemetery by Euclidean and Penrose distance analysis with the skeletons of other 114 cemeteries--mainly from the Carpathian-basin--showed that the majority of the population of the studied cemetery originated from the 9th century population of the area.

We studied how the ratio (K) of the internal:external diameter of human femora follows the biomechanical optima derived earlier by other researchers for marrow-filled tubular bones with circular cross section and minimum mass designed to withstand yield and fatigue, or stiffness, or bending fracture, or impact strengths. With evaluation of radiographs of 107 femora from 57 human mummies the values of K were measured. We found that K(posterior)=0.498+/-0.085 for the posterior radiographic view, and K(medial)=0.589+/-0.070 for the medial view with K(min)=0.345 and K(max)=0.783. The theoretical optima for K depend on the ratio (Q) of the marrow:bone density. Accepting the assumption of earlier authors that Q=0.50, our data show that human femora are optimised to withstand bending fracture, or yield and fatigue strengths. There were no sex-, age- and length-specific differences in K, and the means of K of the right and left femora of individuals were statistically not significantly different. The biomechanical optimization for K of human femora is not finely tuned. Compared with fox femora, K of human femora follows the biomechanical optimum to a much lesser extent. Although the relative wall thickness W=1-K of human femora are optimised, the very low relative mass increment due to deviation of K from the optimum and the considerable intraspecific variance of K make it probable that an accurate optimization of the relative wall thickness is irrelevant in humans.
