Purebred Dog
A dog breed is a particular type of dog that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. These breeds possess distinct traits related to morphology, which include body size and shape, tail phenotype, fur type, etc., but are only one species of dog. Their behavioral traits include guarding, herding, and hunting, and personality traits such as hyper-social behavior, boldness, and aggression. Most breeds were derived from small numbers of founders within the last 200 years. As a result of their adaptability to many environments and breedability for human needs, today dogs are the most abundant carnivore species and are dispersed around the world. A dog breed will consistently produce the physical traits, movement and temperament that were developed over decades of selective breeding. For each breed they re ...

Dog Morphological Variation
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a Domestication of vertebrates, domesticated descendant of the gray wolf. Also called the domestic dog, it was Selective breeding, selectively bred from a population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans, over 14,000 years ago and before the History of agriculture, development of agriculture. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other Canidae, canids. Dogs have been bred for desired behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They have the same number of bones (with the exception of the tail), powerful jaws that house around 42 teeth, and well-developed Dog sense of smell, senses of smell, hearing, and sight. Compared to humans, dogs possess a superior sense of smell and heari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victorian Era
In the history of the United Kingdom and the British Empire, the Victorian era was the reign of Queen Victoria, from 20 June 1837 until her death on 22 January 1901. Slightly different definitions are sometimes used. The era followed the Georgian era and preceded the Edwardian era, and its later half overlaps with the first part of the ''Belle Époque'' era of continental Europe. Various liberalising political reforms took place in the UK, including expanding the electoral franchise. The Great Famine (Ireland), Great Famine caused mass death in Ireland early in the period. The British Empire had relatively peaceful relations with the other great powers. It participated in various military conflicts mainly against minor powers. The British Empire expanded during this period and was the predominant power in the world. Victorian society valued a high standard of personal conduct across all sections of society. The Victorian morality, emphasis on morality gave impetus to soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Divergence
Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes ( mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become reproductively isolated for some period of time, as there is not any genetic exchange anymore. In some cases, subpopulations cover living in ecologically distinct peripheral environments can exhibit genetic divergence from the remainder of a population, especially where the range of a population is very large (see parapatric speciation). The genetic differences among divergent populations can involve silent mutations (that have no effect on the phenotype) or give rise to significant morphological and/or physiological changes. Genetic divergence will always accompany reproductive isolation, either due to novel adaptations via selection and/or due to genetic drift, and is the principal mechanism underlying speciation.

The Wolf's Family Portrait
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Mastiff
A mastiff is a large and powerful Dog type, type of dog. Mastiffs are among the largest dogs, and typically have a short Coat (dog), coat, a long low-set tail and large feet; the skull is large and bulky, the muzzle broad and short (brachycephalic) and the ears drooping and pendant-shaped. European and Asian records dating back 3,000 years show dogs of the mastiff type. Mastiffs have historically been guard dogs, protecting homes and property, although throughout history they have been used as hunting dogs, war dogs and for blood sports, such as dog fighting, fighting each other and other animals, including bulls, bears, and even lions. History Historical and archaeological evidence suggests that mastiffs have long been distinct in both form and function from the similarly large livestock guardian dogs from which they were most likely developed; they also form separate genetic populations. The Fédération Cynologique Internationale and some kennel clubs group the two types toget ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siberian Husky
The Siberian Husky is a dog breed, breed of medium-sized Working dog, working sled dog. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred Coat (dog), double coat, erect triangular ears, and distinctive markings, and is smaller than the similar-looking Alaskan Malamute. Siberian Huskies originated in Northeast Asia where they are bred by the Chukchi people as well as the Koryaks, Koryak, Yukaghir people, Yukaghir and Kamchadals, Kamchadal people of Siberia for sled pulling and companionship. It is an active, energetic, resilient breed, whose ancestors lived in the extremely cold and harsh environment of the Siberian Arctic. William Goosak, a Russian fur trader, introduced them to Nome, Alaska, during the Nome Gold Rush, initially as sled dogs to work the mining fields and for expeditions through otherwise impassable terrain.

Tesem2
Tesem (, ''tjezem''; ) was the ancient Egyptian name for "hunting dog". In popular literature it denotes the prick-eared, leggy dog with a curled tail from the early Egyptian age, but it was also used with reference to the lop-eared "Saluki/Sloughi" type.Brixhe, Jean. 1996 ''Lévriers, chiens de chasse, de travail et de compagnie dans l'Egypte ancienne'' University of Liege It was one of several types of dogs in Ancient Egypt; particularly the latter Saluki/Sloughi type of Tesem, having the appearance most similar to that of a true sighthound. History Three main types of dogs are shown in Ancient Egypt, these being the pariah dog, the greyhound-like dog and a mastiff-type dog. It is assumed that there were two types of greyhound-like breeds, these being the older Tesem and the Saluki/Sloughi type. The two greyhound-types were clearly distinguished in tomb decorations,#Goldwasser2002, Goldwasser (2002): p. 106 with the Tesem thought to be similar to modern pariah dogs.#Goldwasser20 ...

Engagé Mit Einem Indianischen Hundeschlitten By Maximilian Zu Wied-Neuwied
The ''engagé'' system of indentured servitude existed in New France, the U.S. state of Louisiana, and the French West Indies from the 18th and 19th centuries. Engagés in Canada From the 18th century, an engagé (; also spelled '' engagee'') was a French-Canadian man employed to canoe in the fur trade as an indentured servant. He was expected to handle all transportation aspects of frontier river and lake travel: maintenance, loading and unloading, propelling, steering, portaging, camp set-up, navigation, interaction with Indigenous people, etc. The term was also applied to the men who staffed the pirogues on the Lewis and Clark Expedition. Their role can be contrasted with the free, licensed ''voyageurs'', the independent merchant ''coureurs des bois'', as well as seafaring sailors. Engagé were people who were brought to New France by France to work there. By the 19th century the term came to refer to employees of the Hudson's Bay Company of any nationality. White indentu ...
