Odontometrics
Odontometrics is the measurement and study of tooth size. It is used in biological anthropology and bioarchaeology to study human phenotypic variation. The rationale for use is similar to that of the study of dentition, the structure and arrangement of teeth. There are a number of features that can be observed in human teeth through the use of odontometrics. The length and width of teeth are measured from front to back and side to side using calipers. These measurements can be made directly from skeletal material or through dental casts of living humans. The measurements that are reported most commonly are maximum crown length and maximum crown breadth. Uses of odontometrics Determining age ''Linking to the Past'' by Kenneth L. Feder states that "Dental development...provides a valuable gauge of the level of physical maturity and age." The first set of teeth, or the lower central incisors, does not begin to appear until the infant is approximately six-and-a-half months old. ...

Sinodonty And Sundadonty
In anthropology, Sinodonty and Sundadonty are two patterns of features widely found in the dentitions of different populations in East Asia and Southeast Asia. These two patterns were identified by anthropologist Christy G. Turner II as being within the greater "Mongoloid dental complex". The combining forms ''Sino-'' and ''Sunda-'' refer to China and Sundaland, respectively, while refers to teeth. Proto-sundadonty hypothesis Tsunehiko Hanihara (1993) believed that the dental features of Aboriginal Australians have the characteristic of high frequencies of "''evolutionarily conservative characteristics,''" which he called the "proto-sundadont" pattern, as he believed that the dental pattern of Aboriginal Australians was ancestral to that of Southeast Asians.Hanihara, Tsunehiko.

Bioarchaeology
The term bioarchaeology has been attributed to British archaeologist Grahame Clark who, in 1972, defined it as the study of animal and human bones from archaeological sites. Redefined in 1977 by Jane Buikstra, bioarchaeology in the United States now refers to the scientific study of human remains from archaeological sites, a discipline known in other countries as osteoarchaeology, osteology or palaeo-osteology. Compared to bioarchaeology, osteoarchaeology is the scientific study that solely focus on the human skeleton. The human skeleton is used to tell us about health, lifestyle, diet, mortality and physique of the past. Furthermore, palaeo-osteology is simple the study of ancient bones. In contrast, the term bioarchaeology is used in Europe to describe the study of all biological remains from archaeological sites. Although Clark used it to describe just human remains and animal remains (zoology/archaeozoology), increasingly modern archaeologists also include botanical remains (bot ...

Dentition
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have '' heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as ''diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in so ...

Homo Erectus
''Homo erectus'' (; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Several human species, such as '' H. heidelbergensis'' and '' H. antecessor'' — with the former generally considered to have been the ancestor to Neanderthals, Denisovans, and modern humans — appear to have evolved from ''H. erectus''. Its specimens are among the first recognizable members of the genus ''Homo''. ''H. erectus'' was the first human ancestor to spread throughout Eurasia, with a continental range extending from the Iberian Peninsula to Java. Asian populations of ''H. erectus'' may be ancestral to '' H. floresiensis'' and possibly to '' H. luzonensis''. The last known population of ''H. erectus'' is '' H. e. soloensis'' from Java, around 117,000–108,000 years ago. ''H. erectus'' had a more modern gait and body proportions, and was the first human species to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shovel-shaped Incisors
Shovel-shaped incisors (or, more simply, shovel incisors) are incisors whose lingual surfaces are scooped as a consequence of lingual marginal ridges, crown curvature or basal tubercles, either alone or in combination. Shovel-shaped incisors are significantly common in Amerindians from North, Central and South America. They are also common in East and Central Asians, Hungarians, the Inuit and Aleut peoples of Northeast Asia and North America (including but not limited to the Inuit peoples of eastern Alaska, arctic Canada and Greenland). In European and African groups, shovel-shaped upper incisors are uncommon or not present. There is a spectrum of the degree of shoveled-ness, ranging on a scale from 0 to 7 of spatulate incisors to shoveled incisors. It was theorized that positive selection for shovel shaped incisors over the spatulate incisors are more commonly found in anthropoids within cultures that used their teeth as tools due to a greater structural strength in increased sho ...

Aftermath Of The September 11 Attacks
The September 11 attacks transformed the first term of President George W. Bush and led to what he has called the war on terror. The accuracy of describing it as a "war" and its political motivations and consequences are the topic of strenuous debate. The U.S. government increased military operations, economic measures, and political pressure on groups that it accused of being terrorists, as well as increasing pressure on the governments and countries which were accused of sheltering them. October 2001 saw the first military action initiated by the US. Under this policy, NATO invaded Afghanistan to remove the Taliban regime (which harbored al-Qaeda) and capture al-Qaeda forces. Critics point out that the Afghan conflict has contributed to the destabilization of neighbouring Pakistan and Afghanistan has undergone a long war, culminating in the return of the Taliban in 2021. The US government has also asserted that the US invasion of Iraq is connected to 9/11. Immediate Resc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Katrina Disaster Relief
The disaster recovery response to Hurricane Katrina in late 2005 included U.S. federal government agencies such as the Federal Emergency Management Agency (FEMA), the United States Coast Guard (USCG), state and local-level agencies, federal and National Guard soldiers, non-governmental organizations, charities, and private individuals. Tens of thousands of volunteers and troops responded or were deployed to the disaster; most in the affected area but also throughout the U.S. at shelters set up in at least 19 states. Overview Monetary donations were way below the records set by the tsunami and 9/11 relief efforts in the U.S. In a reversal of usual positions, the U.S. received international aid and assistance from numerous countries. The National Disaster Medical System had activated essentially all teams in the country, and pre-staged multiple Disaster Medical Assistance Teams (DMATs), Disaster Mortuary Assistance Teams (DMORTs), and Veterinary Medicine Response Teams (VMATs) in ...

John Wayne Gacy
John Wayne Gacy (March 17, 1942 – May 10, 1994) was an American serial killer and sex offender who raped, tortured, and murdered at least 33 young men and boys. Gacy regularly performed at children's hospitals and charitable events as "Pogo the Clown" or "Patches the Clown", personas he had devised. He became known as the Killer Clown due to his public services as a clown prior to the discovery of his crimes. Gacy committed all of his murders inside his ranch-style house near Norridge, a village in Norwood Park Township in suburban Chicago. Typically, he would lure a victim to his home and dupe him into donning handcuffs on the pretext of demonstrating a magic trick. He would then rape and torture his captive before killing him by either asphyxiation or strangulation with a garrote. Twenty-six victims were buried in the crawl space of his home, and three others were buried elsewhere on his property; four were discarded in the Des Plaines River. Gacy was convicted of t ...

John Wilkes Booth
John Wilkes Booth (May 10, 1838 – April 26, 1865) was an American stage actor who assassinated United States President Abraham Lincoln at Ford's Theatre in Washington, D.C., on April 14, 1865. A member of the prominent 19th-century Booth theatrical family from Maryland, he was a noted actor who was also a Confederate sympathizer; denouncing President Lincoln, he lamented the recent abolition of slavery in the United States. Originally, Booth and his small group of conspirators had plotted to kidnap Lincoln to aid the Confederate cause. They later decided to murder him, as well as Vice President Andrew Johnson and Secretary of State William H. Seward. Although its Army of Northern Virginia, commanded by General Robert E. Lee, had surrendered to the Union Army four days earlier, Booth believed that the Civil War remained unresolved because the Confederate Army of General Joseph E. Johnston continued fighting. Booth shot President Lincoln once in the back of the head. Lincoln' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ted Bundy
Theodore Robert Bundy ( born Cowell; November 24, 1946 – January 24, 1989) was an American serial killer who kidnapped, raped and murdered numerous young women and girls during the 1970s and possibly earlier. After more than a decade of denials, he confessed to 30 murders committed in seven states between 1974 and 1978. His true victim total is unknown and likely significantly higher. Bundy was regarded as charismatic and handsome, and exploited this to win the trust of both his victims and society as a whole. He would typically approach his victims in public places, either feigning a physical impairment such as an injury, or impersonating an authority figure, before bludgeoning them into unconsciousness and taking them to secondary locations to be raped and strangled. Bundy often revisited his victims, grooming and performing sexual acts with the corpses until decomposition and destruction by wild animals made any further interactions impossible. He decapitated at l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dentistry
Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the teeth, gums, and mouth. It consists of the study, diagnosis, prevention, management, and treatment of diseases, disorders, and conditions of the mouth, most commonly focused on dentition (the development and arrangement of teeth) as well as the oral mucosa. Dentistry may also encompass other aspects of the craniofacial complex including the temporomandibular joint. The practitioner is called a dentist. The history of dentistry is almost as ancient as the history of humanity and civilization with the earliest evidence dating from 7000 BC to 5500 BC. Dentistry is thought to have been the first specialization in medicine which have gone on to develop its own accredited degree with its own specializations. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and diseases) for which reas ...
