Neanderthal Anatomy
Neanderthal anatomy is characterised by a long, flat skull and a stocky body plan. When first discovered, Neanderthals were thought to be anatomically comparable to Aboriginal Australians, in accord with historical race concepts. As more fossils were discovered in the early 20th century, French palaeontologist Marcellin Boule defined them as a slouching, apelike species; a popular image until the middle of the century. Neanderthal features gradually accreted in European populations over the Chibanian, Middle Pleistocene, driven by natural selection in a cold climate, as well as genetic drift when populations crashed during glacial periods. This culminated in the "classical Neanderthal" anatomy by the Last Interglacial. The Neanderthal skull is distinctive by namely a rounded supraorbital torus (brow ridge), large orbit (anatomy), orbits (eye sockets) and nose, and an occipital bun at the back of the skull. The jaws and teeth are strong, which may have been a response to habitual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Origin Of Language
The origin of language, its relationship with human evolution, and its consequences have been subjects of study for centuries. Scholars wishing to study the origins of language draw inferences from evidence such as the fossil record, archaeological evidence, and contemporary language diversity. They may also study language acquisition as well as comparisons between human language and systems of animal communication (particularly other primates). Many argue for the close relation between the origins of language and the origins of modern human behavior, but there is little agreement about the facts and implications of this connection. The shortage of direct, empirical evidence has caused many scholars to regard the entire topic as unsuitable for serious study; in 1866, the Linguistic Society of Paris banned any existing or future debates on the subject, a prohibition which remained influential across much of the Western world until the late twentieth century. Various hypotheses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Transitional Fossil
A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. This is especially important where the descendant group is sharply differentiated by gross anatomy and mode of living from the ancestral group. These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation. Because of the incompleteness of the fossil record, there is usually no way to know exactly how close a transitional fossil is to the point of divergence. Therefore, it cannot be assumed that transitional fossils are direct ancestors of more recent groups, though they are frequently used as models for such ancestors. In 1859, when Charles Darwin's ''On the Origin of Species'' was first published, the fossil record was poorly known. Darwin described the perceived lack of transitional fossils as "the most obvious and gravest objection which can be ...

La Chapelle-aux-Saints
La Chapelle-aux-Saints (; ) is a commune in the Corrèze department in central France. History Neanderthal skeleton The La Chapelle-aux-Saints cave, bordering the Sourdoire valley, revealed many archeological artifacts belonging to the late Mousterian techno-complex,BINANT P., 1991 - ''Les sépultures du Paléolithique''. Paris : Errance including the first ever recognized Neanderthal burial discovered on 3 August 1908. Jean and Amédée Bouyssonie, as well as L. Bardon, led archaeological digs in the cave from 1905 to 1908, discovering over 1,000 pieces of stone industry (mainly flint), bones of different fauna including reindeer, bovid, horse, fox, wolf and even a rhinoceros’ tooth. The most spectacular discovery was that of a very well preserved skeleton of an adult Neanderthal man who appears to have been intentionally buried in a rectangular pit deep, long and wide.NOUGIER L.-R., 1963, ''La préhistoire : essai de paléosociologie religieuse''.

La Chapelle-aux-Saints 1
La Chapelle-aux-Saints 1 ("The Old Man") is an almost-complete male Neanderthal skeleton discovered in La Chapelle-aux-Saints, France by A. and J. Bouyssonie, and L. Bardon in 1908. The individual was in his 50s-60s at the time of his death. He was in bad health, having lost most of his teeth and suffering from bone resorption Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones and release the minerals, resulting in a transfer of calcium from bone tissue to the blood. The osteoclasts are multi-nuclea ... in the mandible and advanced arthritis. It is the most convincing example of a possible Neanderthal deliberate burial, but like all claimed Neanderthal burials, it is considered controversial. The remains were first studied by Marcellin Boule, whose reconstruction of Neanderthal anatomy based on la Chapelle-aux-Saints material shaped popular perceptions of the Neanderthals for over thirty years.

Senility
Dementia is a syndrome associated with many neurodegenerative diseases, characterized by a general decline in cognitive abilities that affects a person's ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia is a life-limiting condition, having a significant effect on the individual, their caregivers, and their social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than might be caused by the normal aging process. Several diseases and injuries to the brain, such as a stroke, can give rise to dementia. However, the most commo ...

Rudolf Virchow
Rudolf Ludwig Carl Virchow ( ; ; 13 October 18215 September 1902) was a German physician, anthropologist, pathologist, prehistorian, biologist, writer, editor, and politician. He is known as "the father of modern pathology" and as the founder of social medicine, and to his colleagues, the "Pope of medicine". Virchow studied medicine at the Friedrich Wilhelm University under Johannes Peter Müller. While working at the Charité hospital, his investigation of the 1847–1848 typhus epidemic in Upper Silesia laid the foundation for public health in Germany, and paved his political and social careers. From it, he coined a well known aphorism: "Medicine is a social science, and politics is nothing else but medicine on a large scale". His participation in the Revolution of 1848 led to his expulsion from Charité the next year. He then published a newspaper ''Die Medizinische Reform'' (''The Medical Reform''). He took the first Chair of Pathological Anatomy at the University of Wü ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Aboriginal Australian
Aboriginal Australians are the various indigenous peoples of the Australian mainland and many of its islands, excluding the ethnically distinct people of the Torres Strait Islands. Humans first migrated to Australia 50,000 to 65,000 years ago, and over time formed as many as 500 language-based groups. In the past, Aboriginal people lived over large sections of the continental shelf. They were isolated on many of the smaller offshore islands and Tasmania when the land was inundated at the start of the Holocene inter-glacial period, about 11,700 years ago. Despite this, Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships with Torres Strait Islanders and the Makassar people of modern-day Indonesia. Over the millennia, Aboriginal people developed complex trade networks, inter-cultural relationships, law and religions, which make up some of the oldest, and possibly ''the'' oldest, continuous cultures in the world ...

Racial Hierarchy
A racial hierarchy is a system of stratification that is based on the belief that some racial groups are superior to other racial groups. At various points of history, racial hierarchies have featured in societies, often being formally instituted in law, such as in the Nuremberg Laws in Nazi Germany. Generally, those who support racial hierarchies believe themselves to be part of the 'superior' race and base their supposed superiority on pseudo-biological, cultural or religious arguments. However, systems of racial hierarchy have also been widely rejected and challenged, and many, such as Apartheid have been abolished. The abolition of such systems has not stopped debate around racial hierarchy and racism more broadly. Asia Latin America Liberia Liberia confers nationality solely on the basis of race.

Calvaria (skull)
The calvaria is the top part of the skull. It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. In the human skull, the suture (joint), sutures between the bones normally remain flexible during the first few years of postnatal development, and fontanelles are palpable. Premature complete ossification of these sutures is called craniosynostosis. In Latin, the word ''calvaria'' is used as a feminine noun with plural ''calvariae''; however, many medical texts incorrectly list the word as ''calvarium'', a neuter Latin noun with plural ''calvaria''. Structure The outer surface of the skull possesses a number of landmarks. The point at which the frontal bone and the two parietal bones meet is known as the bregma. The point at which the two parietal bones and the occipital bone meet is kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Evidence As To Man's Place In Nature Page 179
Evidence for a proposition is what supports the proposition. It is usually understood as an indication that the proposition is truth, true. The exact definition and role of evidence vary across different fields. In epistemology, evidence is what Justification (epistemology), justifies beliefs or what makes it rational to hold a certain wikt:doxastic, doxastic attitude. For example, a perceptual experience of a tree may serve as evidence to justify the belief that there is a tree. In this role, evidence is usually understood as a private mental state. In Phenomenology (philosophy), phenomenology, evidence is limited to intuitive knowledge, often associated with the controversial assumption that it provides indubitable access to truth. In the science, scientific evidence is information gained through the scientific method that confirms or disconfirms Hypothesis#Scientific hypothesis, scientific hypotheses, acting as a neutral arbiter between competing Scientific theory, theories.
