It is widely recognized that when marine resources form a significant proportion of the human diet, this results in radiocarbon ages for human remains that are significantly older than the contemporary atmosphere. While there has been widespread assessment of marine [sup.14]C reservoir ages, there has been little study of the freshwater equivalent. However, recent analyses of human bone from archaeological sites in the Danube Valley have confirmed the existence ora large freshwater [sup.14]C reservoir effect. Key-words: radiocarbon dating, reservoir effect, human bones, Iron Gates, diet, stable isotopes, Mesolithic, Lepenski Vir, Schela Cladovei, Vlasac, In studies of the Iron Gates Stone Age (FIGURE 1) there is considerable conflict between the archaeological phasing of sites and radiocarbon dating-based chronologies derived from measurements made on charcoal [...]

Medieval animal remains from the Esztergom archbishopric (Hungary) were screened using 5 mm and 2 mm mesh sizes, aimed at the high-resolution study of fish and bird remains and helping to achieve better comparisons with documentary sources. This is the first medieval assemblage in Hungary recovered using screening. A total of 7,294 animal remains are studied here, representing the 14th and 15th century. The screening resulted in quantities of fish and bird bones. The large find numbers also multiplied the taxonomic diversity. In addition to the remains of new, small-bodied species, bones of young fish showed a diachronic increase in the contribution of carp and young pike to the diet. This seems consonant with the expansion of medieval fish farming. Remains of juvenile birds could also be identified. Some worked bones recovered by screening indicate the manufacturing or reparation of crossbows at the site. Thanks to these details, our material stands out among other contemporaneous animal bone assemblages from the Carpathian Basin. Comparisons between sites, however, must be done with caution, as our data are qualitatively different from others. Large bones of livestock and the near absence of those from large game may be interpreted in the light of other hand-collected samples, while fish and bird remains and even the abundance of brown hare need to be seen in part as a product of high-resolution recovery. The newly discovered spectrum of animal remains could be profitably interpreted in the light of late 15th century accounting books of the archbishop. Although these documentary sources slightly post-date our material, they shed light on the complexities of meat procurement between possibly local production and trade.

Eight newly identified pathological animal remains identified in two Middle Neolithic assemblages (ca 5330-4940 calBC) in northern and western Hungary were placed within the broader context of relevant prehistoric finds. The aim was to understand the underrepresented Middle Neolithic finds in light of the better-known cases from other prehistoric periods. The newly reported cases include arthritic and inflammatory lesions, as well as dental disorders, such as linear enamel hypoplasia, recognized for the first time in the Hungarian Neolithic. Identifications were based on bone macromorphology. When large samples are available, the frequencies of pathological bone specimens reflect the taxonomic composition. Along with the increasing number of cases, longevity related to exploitation for secondary products also became manifest. Therefore, the effects of assemblage size, disease classification and differences between authors (related to training and the time of publication) need to be considered before pathological lesions can be interpreted in terms of diachronic changes in animal husbandry.

Present-day people from England and Wales have more ancestry derived from early European farmers (EEF) than did people of the Early Bronze Age 1 . To understand this, here we generated genome-wide data from 793 individuals, increasing data from the Middle to the Late Bronze Age and Iron Age in Britain by 12-fold, and western and central Europe by 3.5-fold. Between 1000 and 875 BC, EEF ancestry increased in southern Britain (England and Wales) but not northern Britain (Scotland) due to incorporation of migrants who arrived at this time and over previous centuries, and who were genetically most similar to ancient individuals from France. These migrants contributed about half the ancestry of people of England and Wales from the Iron Age, thereby creating a plausible vector for the spread of early Celtic languages into Britain. These patterns are part of a broader trend of EEF ancestry becoming more similar across central and western Europe in the Middle to the Late Bronze Age, coincident with archaeological evidence of intensified cultural exchange 2-6 . There was comparatively less gene flow from continental Europe during the Iron Age, and the independent genetic trajectory in Britain is also reflected in the rise of the allele conferring lactase persistence to approximately 50% by this time compared to approximately 7% in central Europe where it rose rapidly in frequency only a millennium later. This suggests that dairy products were used in qualitatively different ways in Britain and in central Europe over this period., (© 2021.

Objective: This paper seeks to review the possibilities and difficulties in identifying rare diseases in ancient animals. Rare diseases are important in human medicine but seldom discussed in modern veterinary practice., Materials and Methods: A total of 1348 pathological archaeozoological remains, most published in the literature, are evaluated. With the exception of a few animal burials, the majority were recovered from food refuse: deposits composed of co-mingled, single bone fragments., Results: Determination of population-based prevalence is not applicable in animal paleopathology, as almost all lesions occur on isolated bones. Moreover, grave hereditary diseases are rarely detected on animal bones because animals with such disorders seldom survived, except when humans promoted their rare inherited traits., Significance: Rare diseases form a special category in human pathology posing both therapeutic and ethical challenges. While in wild animals natural selection tends to prevent the inheritance of such conditions, curious cases of animal morbidity have been brought about by domestication. Humans sheltered animals of lesser vitality and sometimes even promoted their negative traits. Understanding these phenomena in animal paleopathology will help fine-tuning the rare disease paradigm., Limitations: The definition of rare disease in animal paleopathology can only be assessed based on ancient and modern human correlates, and rare variation could become cultivated traits, ultimately developed into part of "normal" variability as trademark breed characteristics. Taphonomic limitations in recovering osteological evidence of debilitating hereditary diseases in animals are unlikely to improve. Suggestions for further research: Further research will need to focus on the scarce osteological evidence for rare conditions in light of differential diagnoses. The concept of "rare disease" may be worth expanding beyond hereditary conditions in animals considering fundamental differences between past animal and human lifeways., (Copyright © 2021 The Author(s).

Archaeological evidence indicates that pig domestication had begun by ∼10,500 y before the present (BP) in the Near East, and mitochondrial DNA (mtDNA) suggests that pigs arrived in Europe alongside farmers ∼8,500 y BP. A few thousand years after the introduction of Near Eastern pigs into Europe, however, their characteristic mtDNA signature disappeared and was replaced by haplotypes associated with European wild boars. This turnover could be accounted for by substantial gene flow from local European wild boars, although it is also possible that European wild boars were domesticated independently without any genetic contribution from the Near East. To test these hypotheses, we obtained mtDNA sequences from 2,099 modern and ancient pig samples and 63 nuclear ancient genomes from Near Eastern and European pigs. Our analyses revealed that European domestic pigs dating from 7,100 to 6,000 y BP possessed both Near Eastern and European nuclear ancestry, while later pigs possessed no more than 4% Near Eastern ancestry, indicating that gene flow from European wild boars resulted in a near-complete disappearance of Near East ancestry. In addition, we demonstrate that a variant at a locus encoding black coat color likely originated in the Near East and persisted in European pigs. Altogether, our results indicate that while pigs were not independently domesticated in Europe, the vast majority of human-mediated selection over the past 5,000 y focused on the genomic fraction derived from the European wild boars, and not on the fraction that was selected by early Neolithic farmers over the first 2,500 y of the domestication process., Competing Interests: The authors declare no conflict of interest., (Copyright © 2019 the Author(s).

Near Eastern Neolithic farmers introduced several species of domestic plants and animals as they dispersed into Europe. Dogs were the only domestic species present in both Europe and the Near East prior to the Neolithic. Here, we assessed whether early Near Eastern dogs possessed a unique mitochondrial lineage that differentiated them from Mesolithic European populations. We then analysed mitochondrial DNA sequences from 99 ancient European and Near Eastern dogs spanning the Upper Palaeolithic to the Bronze Age to assess if incoming farmers brought Near Eastern dogs with them, or instead primarily adopted indigenous European dogs after they arrived. Our results show that European pre-Neolithic dogs all possessed the mitochondrial haplogroup C, and that the Neolithic and Post-Neolithic dogs associated with farmers from Southeastern Europe mainly possessed haplogroup D. Thus, the appearance of haplogroup D most probably resulted from the dissemination of dogs from the Near East into Europe. In Western and Northern Europe, the turnover is incomplete and haplogroup C persists well into the Chalcolithic at least. These results suggest that dogs were an integral component of the Neolithic farming package and a mitochondrial lineage associated with the Near East was introduced into Europe alongside pigs, cows, sheep and goats. It got diluted into the native dog population when reaching the Western and Northern margins of Europe., (© 2018 The Author(s).)
