Loschbour Man
The Loschbour man (also Loschbur man) is a skeleton of ''Homo sapiens'' from the European Mesolithic discovered in 1935 in Mullerthal, in the commune of Waldbillig, Luxembourg. History The skeleton, nearly complete, was discovered on 7 October 1935 under a rock shelter in Mullerthal on the banks of the Black Ernz. It was found by amateur archeologist and school teacher Nicolas Thill. It is now at the National Museum of Natural History in Luxembourg City. Life Loschbour man was a hunter-gatherer, and the flint tools used for stalking and killing prey (wild boar and deer) were found by his body. He was one of the last of his kind, soon to be supplanted by new populations more likely to herd rather than hunt—and with paler skins. According to DNA tests reported in 2014, Loschbour man was male, was described as having an "intermediate" to light skin tone (90%), brown or black hair (98%), and likely blue eyes (56%). In contrast to 90% of modern Europeans, he was lactose-intol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RTL Télé Lëtzebuerg
RTL Télé Lëtzebuerg is the main television channel in Luxembourg, broadcasting in Luxembourgish. It is part of RTL Group. History The small television market in Luxembourg led to a unique system in Europe: Luxembourg was the only country in the world in which television stations were operated in both the PAL and SECAM formats. Originally, both channels carried the same signal, Tele Luxembourg. Later, the signals were split in the two independent stations RTL-TVI (PAL, system G, on channel 27, the "i" stand for independent), targeting the French-speaking part of Belgium and RTL Télévision (SECAM, system L, on channel 21), targeting France. Both stations initially continued to carry a lot of the same programming, with regards to foreign series and movies, but produced news and game shows for their target audience. As restrictions on operating commercial television stations in Europe were relaxed in the mid-1980s, RTL-TVI moved entirely to Brussels, while the popularity of RTL ...

Prehistoric Luxembourg
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Sapiens Fossils
''Homo'' () is the genus that emerged in the (otherwise extinct) genus ''Australopithecus'' that encompasses the extant species ''Homo sapiens'' ( modern humans), plus several extinct species classified as either ancestral to or closely related to modern humans (depending on the species), most notably '' Homo erectus'' and ''Homo neanderthalensis''. The genus emerged with the appearance of '' Homo habilis'' just over 2 million years ago. ''Homo'', together with the genus '' Paranthropus'', is probably sister to '' Australopithecus africanus'', which itself had previously split from the lineage of '' Pan'', the chimpanzees. '' Homo erectus'' appeared about 2 million years ago and, in several early migrations, spread throughout Africa (where it is dubbed ''Homo ergaster'') and Eurasia. It was likely that the first human species lived in a hunter-gatherer society and was able to control fire. An adaptive and successful species, ''Homo erectus'' persisted for more than a million ...

List Of Human Evolution Fossils
The following tables give an overview of notable finds of Hominini, hominin fossils and Skeleton, remains relating to human evolution, beginning with the formation of the tribe Hominini (the divergence of the Chimpanzee–human last common ancestor, human and chimpanzee lineages) in the late Miocene, roughly 7 to 8 million years ago. As there are thousands of fossils, mostly fragmentary, often consisting of single bones or isolated teeth with complete skulls and skeletons rare, this overview is not complete, but show some of the most important findings. The fossils are arranged by approximate age as determined by radiometric dating and/or incremental dating and the species name represents current consensus; if there is no clear scientific consensus the other possible classifications are indicated. The early fossils shown are not considered ancestors to ''Homo sapiens'' but are closely related to ancestors and are therefore important to the study of the lineage. After 1.5 million ...

Western Hunter-Gatherer
In archaeogenetics, the term Western Hunter-Gatherer (WHG), West European Hunter-Gatherer or Western European Hunter-Gatherer names a distinct ancestral component of modern Europeans, representing descent from a population of Mesolithic hunter-gatherers scattered over Western, Southern and Central Europe, from the British Isles in the west to the Carpathians in the east. Along with the Scandinavian Hunter-Gatherers (SHG) and Eastern Hunter-Gatherers (EHG), the WHGs constituted one of the three main genetic groups in the postglacial period of early Holocene Europe. The border between WHGs and EHGs ran roughly from the lower Danube, northward along the western forests of the Dnieper towards the western Baltic Sea. SHGs were in turn an equal mix of WHGs and EHGs. Once the main population throughout Europe, the WHGs were largely displaced by successive expansions of Early European Farmers (EEFs) during the early Neolithic, but experienced a resurgence during the Middle Neolithic, mai ...

Haplogroup I-M438
Haplogroup I-M438, also known as I2 (ISOGG 2019), is a human DNA Y-chromosome haplogroup, a subclade of Haplogroup I-M170. Haplogroup I-M438 originated some time around 26,000–31,000 BCE. It originated in Europe and developed into several main subgroups : I2-M438*, I2a-L460, I2b-L415 and I2c-L596. The haplogroup can be found all over Europe and reaches its maximum frequency in the Dinaric Alps (Balkans) via founder effect. Examples of basal I-M438* have been found in males from Crete and Sicily . Origin & prehistoric presence Haplogroup I2a was the most frequent Y-DNA among western European mesolithic hunter gatherers (WHG) belonging to Villabruna Cluster. A 2015 study found haplogroup I2a in 13,500 year old remains from the Azilian culture (from Grotte du Bichon, modern Switzerland). Subclades of I2a1 (I-P37.2), namely I-M423 and I-M26 have been found in remains of Western European Hunter-Gatherers dating from 10,000 to 8,000 years before present respectively. In a 201 ...

Human Y-chromosome DNA Haplogroup
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non- recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs). The human Y-chromosome accumulates roughly two mutations per generation. "one mutation in every 30 million base pairs" Y-DNA haplogroups represent major branches of the Y-chromosome phylogenetic tree that share hundreds or even thousands of mutations unique to each haplogroup. The Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived roughly 236,000 years ago in Africa. By examining other bottlenecks most Eurasian men (men from populations outside of Afri ...

Excarnation
In archaeology and anthropology, the term excarnation (also known as defleshing) refers to the practice of removing the flesh and organs of the dead before burial. Excarnation may be achieved through natural means, such as leaving a dead body exposed to the elements or for animals to scavenge; or by butchering the corpse by hand. Following excarnation, some societies retrieved the bones for burial. Excarnation has been practiced throughout the world for hundreds of thousands of years. The earliest archaeological evidence of excarnation is from the Awash River Valley in Ethiopia, 160,000 years ago. Examples of excarnation include 'sky burials' in parts of Asia, the Zoroastrian 'Tower of Silence', and Native American ' tree burials'. Excarnation is practiced for a variety of spiritual and practical reasons, including the Tibetian spiritual belief that excarnation is the most generous form of burial and the Comanche practical concern that in the winter the ground is too hard for an und ...

Lactose-intolerant
Lactose intolerance is a common condition caused by a decreased ability to digest lactose, a sugar found in dairy products. Those affected vary in the amount of lactose they can tolerate before symptoms develop. Symptoms may include abdominal pain, bloating, diarrhea, flatulence, and nausea. These symptoms typically start thirty minutes to two hours after eating or drinking milk-based food. Their severity typically depends on the amount a person eats or drinks. Lactose intolerance does not cause damage to the gastrointestinal tract. Lactose intolerance is due to the lack of the enzyme lactase in the small intestines to break lactose down into glucose and galactose. There are four types: primary, secondary, developmental, and congenital. Primary lactose intolerance occurs as the amount of lactase declines as people age. Secondary lactose intolerance is due to injury to the small intestine. Such injury could be the result of infection, celiac disease, inflammatory bowel disease, or ...
