Tollense Valley Battlefield
The battlefield of the Tollense valley () is a Bronze Age archaeological site in the northern German state of Mecklenburg-Vorpommern at the northern edge of the Mecklenburg Lake District. The site, discovered in 1996 and systematically excavated since 2007, extends along the valley of the small Tollense river, to the east of Weltzin village, on the municipal territories of Burow and Werder. Thousands of bone fragments belonging to many people have been discovered along with further corroborative evidence of battle; current estimates indicate that perhaps 4,000 warriors from Central Europe fought in a battle on the site in the 13th century BC. As the population density was approximately 5 people per square kilometer (13 per square mile), this would have been the most significant battle in Bronze Age Central Europe known so far and makes the Tollense valley currently the largest excavated and archaeologically verifiable battle site of this age in the world. Discovery and excavation ...

Tollense
The Tollense (, from Slavic ''dolenica'' "lowland, (flat) valley") is a river in Mecklenburg-Vorpommern in northeastern Germany, right tributary of the Peene. It has a total length of 95.8 km. The upper course begins near a small lake named ''Mürzsee'', near the village of Blumenholz. A part of it is traditionally called Ziemenbach, flowing to lake Lieps. From this lake to Lake Tollense (''Tollensesee'') it is nowadays called ''Liepskanal''. The section from Lake Tollense to the junction with Peene river near Demmin has a length of 68 km. At this junction, the discharge and basin of Tollense is larger than the discharge and upstream basin of Peene river. The first kilometer of the outflow in Neubrandenburg is called ''Oberbach''. Afterwards, it is reached by two major tributaries, Linde river from the east and Malliner Wasser from the west. The middling section of Tollense river is joined to Zarow river by three different Pseudo-bifurcations. Tollense battle si ...

Palaeogenetics
Paleogenetics is the study of the past through the examination of preserved genetic material from the remains of ancient organisms. Emile Zuckerkandl and Linus Pauling introduced the term in 1963, long before the sequencing of DNA, in reference to the possible reconstruction of the corresponding polypeptide sequences of past organisms. The first sequence of ancient DNA, isolated from a museum specimen of the extinct quagga, was published in 1984 by a team led by Allan Wilson. Paleogeneticists do not recreate actual organisms, but piece together ancient DNA sequences using various analytical methods. Fossils are "the only direct witnesses of extinct species and of evolutionary events" and finding DNA within those fossils exposes tremendously more information about these species, potentially their entire physiology and anatomy. The most ancient DNA sequence to date was reported in February 2021, from the tooth of a Siberian mammoth frozen for over a million years. Applications ...

Millet
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. This crop is favored due to its productivity and short growing season under dry, high-temperature conditions. Millets are indigenous to many parts of the world. The most widely grown millets are sorghum and pearl millets, which are important crops in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies." Descript ...

Population (biology)
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with ind ...

Hallstatt
Hallstatt ( , , ) is a small town in the district of Gmunden, in the Austrian state of Upper Austria. Situated between the southwestern shore of Hallstätter See and the steep slopes of the Dachstein massif, the town lies in the Salzkammergut region, on the national road linking Salzburg and Graz. Hallstatt is known for its production of salt, dating back to prehistoric times, and gave its name to the Hallstatt culture, the archaeological culture linked to Proto-Celtic and early Celtic people of the Early Iron Age in Europe, c. 800–450 BC. Hallstatt is at the core of the Hallstatt-Dachstein/Salzkammergut Cultural Landscape declared as one of the World Heritage Sites in Austria by UNESCO in 1997. It is an area of overtourism. History Finds at Hallstatt extend from about 1200 BC until around 500 BC, and are divided by archaeologists into four phases: Iron Age In 1846, Johann Georg Ramsauer (1795–1874) discovered a large prehistoric cemetery at the Salzberg mines n ...

X-ray Diffraction
X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information. Since many materials can form crystals—such as salts, metals, minerals, semiconductors, as well as various inorganic, organic, and biological molecules—X-ray crystallography has been fundamental in the development of many scientific fields. In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various mat ...

Cavalry
Historically, cavalry (from the French word ''cavalerie'', itself derived from "cheval" meaning "horse") are soldiers or warriors who fight mounted on horseback. Cavalry were the most mobile of the combat arms, operating as light cavalry in the roles of reconnaissance, screening, and skirmishing in many armies, or as heavy cavalry for decisive shock attacks in other armies. An individual soldier in the cavalry is known by a number of designations depending on era and tactics, such as cavalryman, horseman, trooper, cataphract, knight, hussar, uhlan, mamluk, cuirassier, lancer, dragoon, or horse archer. The designation of ''cavalry'' was not usually given to any military forces that used other animals for mounts, such as camels or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the early 17th to the early 18th century as '' dragoons'', a class of mounted infantry which in most armies later evolved into standard cavalry while ...

Sword
A sword is an edged, bladed weapon intended for manual cutting or thrusting. Its blade, longer than a knife or dagger, is attached to a hilt and can be straight or curved. A thrusting sword tends to have a straighter blade with a pointed tip. A slashing sword is more likely to be curved and to have a sharpened cutting edge on one or both sides of the blade. Many swords are designed for both thrusting and slashing. The precise definition of a sword varies by historical epoch and geographic region. Historically, the sword developed in the Bronze Age, evolving from the dagger; the earliest specimens date to about 1600 BC. The later Iron Age sword remained fairly short and without a crossguard. The spatha, as it developed in the Late Roman army, became the predecessor of the European sword of the Middle Ages, at first adopted as the Migration Period sword, and only in the High Middle Ages, developed into the classical arming sword with crossguard. The word '' sword'' continue ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as ultimate tensile strength, strength, ductility, or machinability. The three-age system, archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in mod ...

Human Sacrifice
Human sacrifice is the act of killing one or more humans as part of a ritual, which is usually intended to please or appease gods, a human ruler, an authoritative/priestly figure or spirits of dead ancestors or as a retainer sacrifice, wherein a monarch's servants are killed in order for them to continue to serve their master in the next life. Closely related practices found in some tribal societies are cannibalism and headhunting. Human sacrifice was practiced in many human societies beginning in prehistoric times. By the Iron Age with the associated developments in religion (the Axial Age), human sacrifice was becoming less common throughout Africa, Europe, and Asia, and came to be looked down upon as barbaric during classical antiquity. In the Americas, however, human sacrifice continued to be practiced, by some, to varying degrees until the European colonization of the Americas. Today, human sacrifice has become extremely rare. Modern secular laws treat human sacrifices ...
