Abstract Native animal breeds constitute an invaluable pool of genetic resources in a changing environment. Discovering native breeds and safeguarding their genetic diversity through specific conservation programs is therefore of high importance. Endogenous retroviruses have proved to be a reliable genetic marker for studying the demographic history of sheep (Ovis aries). Previous research has revealed two migratory episodes of domesticated sheep from the Middle East to Europe. The first episode included predominantly ‘primitive populations’, while the second and most recent is hypothesised to have included sheep with markedly improved wool production. To examine whether the recently discovered Kihnu native sheep in Estonia have historically been part of the first migratory episode and to what extent they have preserved primitive genetic characters, we analysed retroviral insertions in 80 modern Kihnu sheep and 83 ancient sheep from the Bronze Age to Modern Period (850 BCE–1950 CE). We identified that the Kihnu sheep have preserved ‘primitive’, ‘Nordic’, and other ‘ancient’ retrotypes that were present both in archaeological and modern samples, confirming their shared ancestry and suggesting that contemporary Kihnu native sheep originate from the first migratory episode. However, over the course of history, there has been a gradual decrease in the frequency of primitive retrotypes. Furthermore, Kihnu sheep possessed several ‘novel’ retrotypes that were absent in archaeological individuals, but were shared with improvement breeds, suggesting recent crossing within the last two centuries. To preserve these ancient lineages, our results are being applied in the conservation program of the Kihnu Native Sheep Society.

It is known that the Oxus civilization in the Bronze Age, with its unique material culture, interacted with a number of cultural countries: the Indian Valley, Iran, Mesopotamia, Elam and other regions. As a result of these relationships, interactions and interactions are formed. Archaeologists turn to archaeological and written sources to shed light on the historiography of this period. This research is devoted to the history of cultural relations between the Oxus civilization and the countries of the Arabian Gulf in the Bronze Age. The article highlights cultural ties based on an analysis of stamp seals and unique artifacts.Key words: Dilmun, Magan, marine shell, Arabian Gulf, Bahrain, Mesopotamia, Harappa, Gonur, Afghanistan

Many decades the life and work of Mikhail Petrovich Gryaznov (1902-1984) was connected with the State Hermitage museum. Long-term friendship bound him with Vladimir Ivanovich Matyushchenko (1928-2005). These archaeologists were lucky in the excavations in the field and in the office behind a desk that was reached by stressful daily work. The most valuable materials from the excavations of M.P. Gryaznov were transferred to the Hermitage (Pazyryk-1, Arzhan-1), and in the museum's funds he taught a course in tracology for students of LSU. Archaeologists are well aware of the scientific works of VI. Matyushchenko on the history of Siberian archaeology, materials from excavations of the Bronze Age sites in the Tomsk and Omsk regions (Elovka, Rostovka and others), and the mounds of the Xiongnu era in Sidorovka. This article briefly discusses the main stages of M.P. Gryaznov's work in the Hermitage and his further relations with this museum. The author of the article was familiar with M.P. Gryaznov and VI. Matyushchenko, studied archaeology with them, gained experience and repeatedly helped them, both in the Hermitage and beyond. Keywords: M.P Gryaznov, V.I. Matyushchenko, hermitage, Pazyryk, Arzhan, state award

Four letters written in 1879, 1880, and 1884, by Thomas B. Sandwith, the British Consul in Crete, to the British Museum throw light on the early history of the site of the Bronze Age palace at Knossos. The first of these letters (1879) contains a brief eyewitness account of the excavations of Minos Kalokairinos there in the winter of 1878–9 and urges the British Museum to continue his work. The two later letters (1884) deal with his gift of a pithos from the palace excavations to the Museum. The letters also refer to clandestine excavations in the Sanctuary of Demeter at Knossos.

In this article I examine how long-term economic strategies in the Bronze Age of northern Europe between 2300 and 500 BCE transformed the environment and thus created and imposed new ecological constraints that finally led to a major social transformation and a "dark age" that became the start of the new long-term cycle of the Iron Age. During the last 30 years hundreds of well-excavated farmsteads and houses from south Scandinavia have made it possible to reconstruct the size and the structure of settlement and individual households through time. During the same period numerous pollen diagrams have established the history of vegetation and environmental changes. I will therefore use the size of individual households or farmsteads as a parameter of economic strength, and to this I add the role of metal as a triggering factor in the economy, especially after 1700 BCE when a full-scale bronze technology was adopted and after 500 BCE when it was replaced by iron as the dominant metal. A major theoretical concern is the relationships between micro- and macroeconomic changes and how they articulated in economic practices. Finally the nature of the "dark age" during the beginning of the Iron Age will be discussed, referring to Sing Chew's use of the concept (Chew 2006).

Despite the important roles that horses have played in human history, particularly in the spread of languages and cultures, and correspondingly intensive research on this topic, the origin of domestic horses remains elusive. Several domestication centers have been hypothesized, but most of these have been invalidated through recent paleogenetic studies. Anatolia is a region with an extended history of horse exploitation that has been considered a candidate for the origins of domestic horses but has never been subject to detailed investigation. Our paleogenetic study of pre- and protohistoric horses in Anatolia and the Caucasus, based on a diachronic sample from the early Neolithic to the Iron Age (~8000 to ~1000 BCE) that encompasses the presumed transition from wild to domestic horses (4000 to 3000 BCE), shows the rapid and large-scale introduction of domestic horses at the end of the third millennium BCE. Thus, our results argue strongly against autochthonous independent domestication of horses in Anatolia.

The history of archaeology of Greece as we know it today begins with prehistoric investigations that took place in the 19th century. Early excavations by Heinrich Schliemann, Arthur Evans, and Wilhelm Dörpfeld, along with Greek colleagues like Christos Tsountas, Panagiotis Stamatakis, Valerios Stais, and Antonios Keramopoulos laid the foundation for systematic, stratigraphic excavations. Research was heavily directed by ancient Greek texts, primarily the epic poems of Homer. Efforts to find archaeological truth to the legendary tales of the ancient heroes continue to be problematic, but, to a degree, early excavations revealed a rich and fascinating period of Greece’s development. Although the archaeological discoveries of Greek prehistory date to an age centuries older than Homer, the discoveries shed light on a vast, rich archaeological history, one upon which the Homeric tales were, at least partially, based. Early discoveries of prehistoric texts, especially on Crete with scripts in Hieroglyphic Minoan, Linear A (non-Greek), and Linear B (Greek), along with the enigmatic Phaistos disc, have expanded our understanding of the history of the Greek language and Greek people.

Genomic studies conducted on ancient individuals across Europe have revealed 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 of a number of nuclear loci of interest of 243 individuals sampled across present-day France over a period spanning 7,000 y, complemented with a partially overlapping dataset of 58 low-coverage genomes. This panel provides a high-resolution transect of the dynamics of maternal and paternal lineages in France as well as of autosomal genotypes. Parental lineages and genomic data both revealed demographic patterns in France for the Neolithic and Bronze Age transitions consistent with neighboring regions, first with a migration wave of Anatolian farmers followed by varying degrees of admixture with autochthonous hunter-gatherers, and then substantial 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 Magdalenian-associated ancestry in hunter-gatherer populations outside of 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.
