Neanderthal 1
Feldhofer 1 or Neanderthal 1 is the scientific name of the 40,000-year-old type specimen fossil of the species ''Homo neanderthalensis'', found in August 1856 in a German cave, the Kleine Feldhofer Grotte in the Neandertal valley, east of Düsseldorf. In 1864 the fossil's description was first published in a scientific magazine and officially named. William King: ''The Reputed Fossil Man of the Neanderthal''. In: ''Quarterly Journal of Science''. Band 1, 1864, S. 88–97Volltext (PDF; 356 kB)/ref> However, the find was not the first Neanderthal fossil discovery. Other Neanderthal fossils had been discovered earlier, but their true nature and significance had not been recognized, and therefore no separate species' name was assigned. The discovery was made by limestone quarry miners. Neanderthal 1 consists of a skullcap, two femora, the three right arm bones, two of the left arm bones, ilium, and fragments of a scapula and ribs. The fossils were given to Johann Carl Fuhlro ...

Neandertal 1856
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor ''H. heidelbergensis'' is also unclear. The oldest potential Neanderthal bones date to 430,000 years ago, but the classification r ...

Femur
The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint. By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest. Structure The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have thicker pelvic bones, causing their femora to converge more than in males. In the condition ''genu valgum'' (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is ''genu varum'' (bow-leggedness). In the general populatio ...

The Observer
''The Observer'' is a British newspaper published on Sundays. It is a sister paper to ''The Guardian'' and ''The Guardian Weekly'', whose parent company Guardian Media Group Limited acquired it in 1993. First published in 1791, it is the world's oldest Sunday newspaper. History Origins The first issue, published on 4 December 1791 by W.S. Bourne, was the world's first Sunday newspaper. Believing that the paper would be a means of wealth, Bourne instead soon found himself facing debts of nearly £1,600. Though early editions purported editorial independence, Bourne attempted to cut his losses and sell the title to the government. When this failed, Bourne's brother (a wealthy businessman) made an offer to the government, which also refused to buy the paper but agreed to subsidise it in return for influence over its editorial content. As a result, the paper soon took a strong line against radicals such as Thomas Paine, Francis Burdett and Joseph Priestley. 19th century In 180 ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ...

Hermann Schaaffhausen
Hermann Schaaffhausen (19 July 1816, Koblenz – 26 January 1893, Bonn) was a German anatomist, anthropologist, and paleoanthropologist. Biography Hermann Schaaffhausen was the son of Josef Hubert Schaaffhausen and Anna Maria Wachendorf. He studied medicine at the University of Berlin and received his doctorate degree in 1839, and became a Professor of Anatomy at the University of Bonn. Schaaffhausen soon became involved in research in physical anthropology and the study of prehistoric humans in Europe. He is best known for his study of the Neanderthal fossils (together with J.C. Fuhlrott). He was a member of several scientific societies, including the Naturhistorischen Vereins der preussischen Rheinlande und Westphalens (Natural History Society of the Rhineland and Westphalia) located in Bonn, the Vereins von Alterthumsfreunden im Rheinlande (Association of the Friends of Antiquity in the Rhineland), and was an honorary member of the Deutsche Gesellschaft für Anthropologie, ...

Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function (biology), function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic research, basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic scale, macroscopic and microscopic scale, microscopic. Gross anatomy, Macroscopic anatomy, or gross anatomy, is the examination of an ...

Teacher
A teacher, also called a schoolteacher or formally an educator, is a person who helps students to acquire knowledge, competence, or virtue, via the practice of teaching. ''Informally'' the role of teacher may be taken on by anyone (e.g. when showing a colleague how to perform a specific task). In some countries, teaching young people of school age may be carried out in an informal setting, such as within the family (homeschooling), rather than in a formal setting such as a school or college. Some other professions may involve a significant amount of teaching (e.g. youth worker, pastor). In most countries, ''formal'' teaching of students is usually carried out by paid professional teachers. This article focuses on those who are ''employed'', as their main role, to teach others in a ''formal'' education context, such as at a school or other place of ''initial'' formal education or training. Duties and functions A teacher's role may vary among cultures. Teachers may provide ...

Johann Carl Fuhlrott
Prof. Dr. Johann Carl Fuhlrott (31 December 1803, Leinefelde, Germany – 17 October 1877, Wuppertal) was an early German paleoanthropologist. He is famous for recognizing the significance of the bones of Neanderthal 1, a Neanderthal specimen discovered by German laborers who were digging for limestone in Neander valley (''Neanderthal'' in German) in August 1856. Originally disregarded, Fuhlrott, to his eternal credit, had the insight to recognize them for what they were: the remains of a previously unknown type of human. Biography His parents were the innkeeper Johannes Philipp Fuhlrott and his wife Maria Magdalena, née Nussbaum. His parents had died by the time he was ten and he was raised by his uncle, the Catholic priest Carl Bernhard Fuhlrott, in Seulingen. In 1835 he married Josepha Amalia Kellner (1812–1850), with whom he had six children. After studying mathematics and natural sciences at the University of Bonn, Fuhlrott became a teacher at the Gymnasium in Elberfel ...

Rib Cage
The rib cage, as an enclosure that comprises the ribs, vertebral column and sternum in the thorax of most vertebrates, protects vital organs such as the heart, lungs and great vessels. The sternum, together known as the thoracic cage, is a semi-rigid bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton. A typical human thoracic cage consists of 12 pairs of ribs and the adjoining costal cartilages, the sternum (along with the manubrium and xiphoid process), and the 12 thoracic vertebrae articulating with the ribs. Together with the skin and associated fascia and muscles, the thoracic cage makes up the thoracic wall and provides attachments for extrinsic skeletal muscles of the neck, upper limbs, upper abdomen and back. The rib cage intrinsically holds the muscles of respiration ( diaphragm, intercostal muscles, etc.) that are crucial for active inhalation and forced exhalation, and ...
