- The Bronze Age of Eurasia (around 3000-1000 BC) was a period of major cultural changes. However, there is debate about whether these changes resulted from the circulation of ideas or from human migrations, potentially also facilitating the spread of languages and certain phenotypic traits. We investigated this by using new, improved methods to sequence low-coverage genomes from 101 ancient humans from across Eurasia. We show that the Bronze Age was a highly dynamic period involving large-scale population migrations and replacements, responsible for shaping major parts of present-day demographic structure in both Europe and Asia. Our findings are consistent with the hypothesized spread of Indo-European languages during the Early Bronze Age. We also demonstrate that light skin pigmentation in Europeans was already present at high frequency in the Bronze Age, but not lactose tolerance, indicating a more recent onset of positive selection on lactose tolerance than previously thought.

- Hepatitis B virus (HBV) is a major cause of human hepatitis. There is considerable uncertainty about the timescale of its evolution and its association with humans. Here we present 12 full or partial ancient HBV genomes that are between approximately 0.8 and 4.5 thousand years old. The ancient sequences group either within or in a sister relationship with extant human or other ape HBV clades. Generally, the genome properties follow those of modern HBV. The root of the HBV tree is projected to between 8.6 and 20.9 thousand years ago, and we estimate a substitution rate of 8.04 x 10(-6-)1.51 x 10(-5) nucleotide substitutions per site per year. In several cases, the geographical locations of the ancient genotypes do not match present-day distributions. Genotypes that today are typical of Africa and Asia, and a subgenotype from India, are shown to have an early Eurasian presence. The geographical and temporal patterns that we observe in ancient and modern HBV genotypes are compatible with well-documented human migrations during the Bronze and Iron Ages(1,2). We provide evidence for the creation of HBV genotype A via recombination, and for a long-term association of modern HBV genotypes with humans, including the discovery of a human genotype that is now extinct. These data expose a complexity of HBV evolution that is not evident when considering modern sequences alone.

- The remarkable typological parallels between Carpathian and Scandinavian metalwork, especially from around 1700 to 1500 BC, have long been stressed as evidence that the Carpathian tell communities supplied the Scandinavians with copper. Thus, this study's main objective was to investigate if Bronze Age societies in Scandinavia and the Carpathian basin utilized the same copper sources. To test this hypothesis, analyses, comprising lead isotopes and trace elements, were executed on bronzes from Scandinavia and Hungary. In the current study, the Hungarian data set of 31 artefacts from the famous Szazhalombatta hoard and its nearby settlement, is in detail compared to 62 Scandinavian artefacts of various types. The outcome points to that Scandinavia and Hungary partly shared copper sources between 1700 and 1500 BC. The most potential sources are the ones from the Slovak Ore Mountains and Mitterberg in Austria. However, the Scandinavian artefacts from this period also show consistency with additional copper sources, such as Great Orme in Wales and in the Italian Alps. The findings of this study support both the traditional theory, which stated that metal supplies and metalworking traditions were closely related, and the more recent insight, which suggests that style and content may have entirely separate origins. As a result, the intricacy of the production, exchange, and consumption patterns of metal throughout Bronze Age Europe cannot be explained by a simple model that equates stylistic influence and metal suppliers.
