The dog'" ("Canis lupus familiaris",) is a domesticated subspecies of the gray wolf, a member of the Canidae family of the order Carnivora. The term is used for both feral and pet varieties. The domestic dog has been one of the most widely kept working and companion animals in human history. The domestication of the gray wolf took place in a handful of events roughly 15,000 years ago in central Asia. The dog quickly became ubiquitous across culture in all parts of the world, and was extremely valuable to early human settlements. For instance, it is believed that the successful emigration across the Bering Strait might not have been possible without sled dogs. As a result of the domestication process, the dog developed a sophisticated intelligence that includes unparalleled social cognition and a simple theory of mind that is important to their interaction with humans. These social skills have helped the dog to perform in myriad roles, such as hunting, herding, protection, and, more recently, assisting handicapped individuals. Currently, there are estimated to be 400 million dogs in the world. Over the 15,000 year span that the dog had been domesticated, it diverged into only a handful of landraces, groups of similar animals whose morphology and behavior have been shaped by environmental factors and functional roles. Humans did not take an active, intentional role in this process until the last few hundred years. As the modern understanding of genetics developed, humans began to intentionally breed dogs for a wide range of specific traits. Through this process, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the withers ranges from a few inches in the Chihuahua to a few feet in the Irish Wolfhound; color varies from white through grays (usually called "blue'") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to shed this coat, but non-shedding breeds are also popular. Etymology and related terminology. "Dog" is the common use term that refers to members of the subspecies "Canis lupus familiaris". The term is sometimes used to refer to a wider range of species: it can be used to refer to any mammal belonging to the family Canidae, which includes wolves, foxes, jackals, and coyotes; it can be used to refer to the subfamily of Caninae, or the genus Canis, also often called the "true dogs". Some members of the family have "dog" in their common names, such as the raccoon dog and the African wild dog. A few animals have "dog" in their common names but are not canids, such as the prairie dog and the dog fish. The English word "dog" can be traced back to the Old English "docga", a "powerful breed of canine". The term may derive from Proto-Germanic "*dukkōn", represented in Old English "finger-docce" ("finger-muscle"). Due to the linguistically archaic structure of the word, the term "dog" may ultimately derive from the earliest layer of Proto-Indo-European vocabulary, reflecting the role of the dog as the earliest domesticated animal. The English word "hound", which refers to a specific breed group in English, means "dog" in general in other Germanic languages; it is cognate to German "hund", Dutch "hond", common Scandinavian "hund", and Icelandic "hundur". "Hound" itself is derived from the Proto-Indo-European "*kwon-", which is also the direct root of the Greek κυων (kuōn) and the indirect root of the Latin "canis" through the variant form "*kani-". In breeding circles, a male canine is referred to as a "dog", while a female is called a "bitch". A group of offspring is a "litter". The father of a litter is called the "sire", and the mother is called the "dam". Offspring are generally called "pups" or "puppies" until they are about a year old. The process of birth is "whelping". Taxonomy and evolution. The domestic dog was originally classified as "Canis familiaris" and "Canis familiarus domesticus" by Linnaeus in 1758, and is currently classified as "Canis lupus familiaris", a subspecies of the gray wolf "Canis lupus", by the Smithsonian Institution and the American Society of Mammalogists. Overwhelming evidence from behavior, vocalizations, morphology, and molecular biology led to the contemporary scientific understanding that a single species, the gray wolf, is the common ancestor for all breeds of domestic dogs, however the timeframe and mechanisms by which dogs diverged are controversial. The current consensus among biologists and archaeologists is that no one can be sure when dogs were domesticated. There is conclusive evidence that dogs genetically diverged from their wolf ancestors at least 15,000 years ago but most believe domestication to have occurred much earlier. The evidence cited for an earlier divergence comes from archaeological findings and mitochondrial DNA studies, both of which are inconclusive. The archaeological evidence demonstrates that the domestication of dogs occurred prior to 15,000 years ago. Some genetic evidence indicates that the domestication of dogs from their wolf ancestors began in the late Upper Paleolithic close to the Pleistocene Holocene boundary, between 17,000 and 14,000 years ago. The earliest dog fossils, two large skulls from Russia and a mandible from Germany, date from roughly 14,000 years ago. Their likely ancestor is the large Eurasian wolf ("Canis lupus lupus"). Remains of smaller dogs from Natufian cave deposits in the Middle East have been dated to around 10,000 to 12,000 years ago. There is a great deal of archealogical evidence for dogs throughout Europe and Asia around this period and through the next two thousand years (roughly 8,000 to 10,000 years ago), with fossils uncovered in Germany, the French Alps, and Iraq, and cave paintings in Turkey. DNA studies have provided a wider range of possible divergence dates, from 15,000 to 40,000 years ago, to as much as 100,000 to 140,000 years ago. This evidence depends on a number of assumptions that others claim are violated. Genetic studies are based in comparisons of genetic diversity between species, and depend on a calibration date, such as the wolf-coyote divergence date, which is estimated to be roughly 1 million years ago. If this divergence date is closer to 750,000 or 2 million years ago, then genetic analyses would be interpreted very differently. Furthermore, it is believed that the genetic diversity of wolves has been in decline for the last 200 years, and that the genetic diversity of dogs has been reduced by selective breeding, which could bias DNA analyses to support an earlier divergence. The genetic evidence for the domestication event occurring in East Asia is also subject to violations of assumptions. These conclusions are based on the location of maximal genetic divergence, assumes that hybridization does not occur, and that breeds remain geographically localized. Although these assumptions hold for many species, there is good reason to believe that they do not hold for canines. Genetic analyses indicate all dogs are likely descended from a handful of domestication events with a small number of founding females, although there is evidence that domesticated dogs interbred with local populations of wild wolves on several occasions. Data suggests that dogs first diverged from wolves in East Asia, and that these domesticated dogs then quickly migrated throughout the world, reaching the North American continent around 8000 B.C. The oldest groups of dogs, which show the greatest genetic variability and are the most similar to their wolf ancestors, are primarily Asian and African breeds, including the Basenji, Saluki, Afghan Hound, Tibetan Terrier, Lhasa Apso, Chow Chow, Pekingese, Shar-Pei, Shi Tzu, Akita, Shiba Inu, Alaskan Malamute, Siberian Husky, and Samoyed. Some breeds that were thought to be very old, such as the Pharaoh Hound, Ibizan Hound, and Norwegian Elkhound, are now known to have been recreated more recently. There is a great deal of controversy surrounding the evolutionary framework for the domestication of dogs. At least three early species of the "Homo" genus began spreading out of Africa roughly 400,000 years ago, and thus lived for a considerable period in contact with canine species. Despite this, there is no evidence of any adaptation of these canine species to the presence of the close relatives of modern man. If dogs were domesticated, as believed, roughly 15,000 years ago, the event (or events) would have coincided with a large expansion in human territory and the development of agriculture. This has led some biologists to suggest that one of the forces that led to the domestication of dogs was a shift in human lifestyle in the form of established human settlements. Permanent settlements would have coincided with a greater amount of disposable food and would have created a barrier between wild and anthropogenic canine populations. Biology. Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Nevertheless, their morphology is based on that of their wild ancestors, gray wolves. Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused | A spoon'" is a utensil consisting of a small shallow bowl, oval or round, at the end of a handle. A type of cutlery (usually called flatware in the United States), especially as part of a place setting, it is used primarily for serving and eating liquid or semisolid food (sometimes called "spoon-meat"), and solid foods such as rice and cereal which cannot easily be lifted with a fork. Spoons are also used in food preparation to measure, mix, stir and toss ingredients. They can be made from metal (notably flat silver or silverware, plated or solid), wood or plastic. Abbreviation: sp. History. The earliest northern European spoon would seem to have been a chip or splinter of wood; Greek references point to the early and natural use of shells, such as those that are still used by primitive peoples. Ancient Indian texts also refer to the use of spoons. For example, the Rigveda refers to spoons during a passage describing the reflection of light as it "touches the spoon's mouth" (RV 8.43.10). Preserved examples of various forms of spoons used by the ancient Egyptians include those composed of ivory, flint, slate and wood; many of them carved with religious symbols. The spoons of the Greeks and Romans were chiefly made of bronze and silver and the handle usually takes the form of a spike or pointed stem. There are many examples in the British Museum from which the forms of the various types can be ascertained, the chief points of difference being found in the junction of the bowl with the handle. Middle Ages spoons at Chillon Castel Medieval spoons for domestic use were commonly made of cow horn or wood, but brass, pewter, and latten spoons appear to have been common in about the 15th century. The full descriptions and entries relating to silver spoons in the inventories of the royal and other households point to their special value and rarity. The earliest English reference appears to be in a will of 1259. In the wardrobe accounts of Edward I for the year 1300 some gold and silver spoons marked with the "fleur-de-lis", the Paris mark, are mentioned. One of the most interesting medieval spoons is the coronation spoon used in the anointing of the English sovereign. The sets of Apostle Spoons, popular as christening presents in Tudor times, the handles of which terminate in heads or busts of the apostles, are a special form to which antiquarian interest attaches. The earlier English spoon-handles terminate in an acorn, plain knob or a diamond; at the end of the 16th century, the baluster and seal ending becomes common, the bowl being fig-shaped. During The Restoration, the handle becomes broad and flat, the bowl is broad and oval and the termination is cut into the shape known as the hind's foot. In the first quarter of the 18th century, the bowl becomes narrow and elliptical, with a tongue or rat's tail down the back, and the handle is turned up at the end. The modern form, with the tip of the bowl narrower than the base and the rounded end of the handle turned down, came into use about 1760. Types and uses. Spoons are used primarily for eating liquid or semi-liquid foods, such as soup, stew or ice cream, and very small or powdery solid items which cannot be easily lifted with a fork, such as rice, sugar, cereals and green peas. In Southeast Asia, spoons are the primary utensil used for eating; forks are used only to push food onto the spoon. Spoons are also widely used in cooking and serving. In baking, batter is usually thin enough to pour or drop from a spoon; a mixture of such consistency is sometimes called "drop batter”. Rolled dough dropped from a spoon to a cookie sheet can be made into rock cakes and other cookies, while johnnycake may be prepared by dropping spoonfuls of cornmeal onto a hot greased griddle. A spoon is similarly useful in processing jelly, sugar and syrup. A test sample of jelly taken from a boiling mass may be allowed to slip from a spoon in a sheet, in a step called "sheeting". At the "crack" stage, syrup from boiling sugar may be dripped from a spoon, causing it to break with a snap when chilled. When boiled to 240°F. and poured from a spoon, sugar forms a filament, or "thread". Hot syrup is said to "pearl" when it forms such a long thread without breaking when dropped from a spoon. Used for stirring, a spoon is passed through a substance with a continued circular movement for the purpose of mixing, blending, dissolving, cooling, or preventing sticking of the ingredients. Mixed drinks may be "muddled" by working a spoon to crush and mix ingredients such as mint and sugar on the bottom of a glass or mixer. Spoons are employed for mixing certain kinds of powder into water to make a sweet or nutritious drink. A spoon may also be employed to toss ingredients by mixing them lightly until they are well coated with a dressing. A spoonful'"—the amount of material a spoon contains or can contain—is used as a standard unit of measure for volume in cooking, where it normally signifies a "'teaspoonful'". It is abbreviated "coch" or "cochl", from Latin "cochleare". "Teaspoonful" is often used in a similar way to describe the dosage for over the counter medicines. Dessert spoonful and tablespoonful may also be found in drink and food recipes. A teaspoon holds about 5ml and a tablespoon about 15ml. For storage, spoons and knives were sometimes placed in paired "knife boxes", which were often ornate wooden containers with sloping top, used especially during the 18th century. On the table, an ornamental utensil called a "nef", shaped like a ship, might hold a napkin, knife and spoon. The souvenir spoon generally exists solely as a decorative object commemorating an event, place, or special date. Spoons can also be used as a musical instrument. To "spoon-feed" oneself or another can simply mean to feed by means of a spoon. Metaphorically, however, it often means to present something to a person or group so thoroughly or wholeheartedly as to preclude the need of independent thought, initiative or self-reliance on the part of the recipient; or to present information in a slanted version, with the intent to preclude questioning or revision. Someone who accepts passively what has been offered in this way is said to have been spoon-fed. Manufacture. For machine-made spoons, the basic shape is cut out from a sheet of sterling silver, nickel silver alloy or stainless steel. The bowl is cross rolled between two pressurized rollers to produce a thinner section. The handle section is also rolled to produce the width needed for the top end. The blank is then cropped to the required shape, and two dies are used to apply the pattern to the blank. The fash is then removed using a lynisher, and the bowl is formed between two dies and bent. To make a spoon the traditional by way of handforging, a bar of silver is marked up to the correct proportions for the bowl and handle. It is then heated until red hot and held in tongs and using the hammer and anvil, beaten into shape. The tip of the bar is pointed to form the tip of the bowl, then hammered to form the bowl. If a heel is to be added, a section down the centre is left thicker. The edges of the bowl and the tip of the spoon are left thicker as this is where most of the thickness is needed. The handle is then started and hammered out to length going from thick at the neck and gradually tapering down in thickness giving a balanced feel. During this process the piece becomes very hard and has to be annealed several times, then worked again until the final shape is achieved. The bowl is filed to shape, often using a metal template. The bowl is then formed using a tin cake and spoon stake. The molten tin is poured around the spoon stake and left to harden. The handle is then bent down to 45 degrees, and the spoon is hammered into the tin using the spoon stake and a heavy hammer, to form the bowl. The bend in the handle is then adjusted to match the other spoons in the set and so it sits correctly on the table. The bowl is then filed level, a process called striking off. The surfaces are filed, first with a rough file to remove the fire stain from the surface, then with a smooth file. It is then buffed to remove any file marks and fire stain from inside the bowl and is polished to the desired finish. During the hand-forging process the spoon will have been hit with a hammer over 300 hundred times. A machine made spoon receives one or two blows from a press. Bibliography.
