The wolf has had an influence on the culture, art, and lore of human society since before historical times. The wolf is one of the most misunderstood animals in all of history. Theirs is a proud, yet sad, history.
The wolf and dog are different species but yet have so much in common. Dogs were originally classified as “Canis familiaris”, in 1758. However, in 1993, dogs were reclassified as a subspecies of the gray wolf and renamed “canis lupus familiaris.”While it is true that there have been speculations that dogs may have descended from several species of canines, the wolf appears to ultimately be the ancestor of man’s best friend. The dog and wolf both share the same number of chromosomes (78, arranged in 39 pairs).The dog and the wolf can mate and give life to offspring. There are good chances indeed, that in the past the two species may have interbred, whether because of feral dogs may have escaped from being domesticated or because some wolves may have separated from their pack and started looking for a soul mate. At the same time, the outward appearance of wolves and dogs is markedly different. The wolf’s skeleton is higher and has a more arched spine. The wolf’s legs are heavier in build and are usually longer. Dogs and wolves run differently. A dog runs with a loping, almost casual gait, while wolves run in a springing motion with force from the hind legs propelling them forward. One main difference between the wolf and the dog is the mating; a dog can come into heat twice a year while the wolf comes into heat only once a year, usually in the spring. This might be to allow ample time for the pups to grow and flourish before the winter season comes. There is one exception: the Bensenji dog breed comes into heat only once a year. Physically, wolves and dogs today appear as almost different species, if we think about the diversity in dogs we...

How Dogs Evovle

...How Dogs have Evolved Every wonder how “Man’s best friend” evolved? With over 350 different breeds, from the Chihuahua to the Great Dane, all dogs have descended from the Grey Wolf. The domestication of dogs by man dates back at least twelve thousand years. Domestication of the wolf may have begun with orphaned wolf cubs brought into villages and raised by children. Ancient man may have also started the domestication process by befriending wolves which helped them hunt and drive herds. (Kodat, 2002) Having a semi-tame wolves has its advantages. For example, the acute hearing of the wolve would alarm the human if danger was near at night. However, as civilization evolved, the jobs of dogs became more varied and specific; as a result, different breeds were created to handle different jobs. Selective breeding has allowed human manipulation to create the traits that you see in your dog today, such as the pushed-in face of the pug, or the speed of they greyhound to catch its prey. The domestic dog has been the most widely kept working, hunting and companion animal in human history. The dog quickly became ubiquitous across world cultures, and was extremely valuable to early human settlements. For instance, it is believed the successful emigration across the Bering Strait might not have been possible without sled dogs (Kodat, 2002). No matter how far the dog evolves from it ancestors, there is still a great deal of wolf present in the domestic dog. Dogs are still genetically......

Wolves

...one another’s fur. Wolves are carnivores, they mainly eat meat. They prefer to hunt and eat large animals such as moose, muskoxen, elk, and caribou. These creatures are powerful, armed with sharp hooves, and fierce horns or antlers. They can only be hunted by wolves in a pack. Other wild dogs like cats, bears, raccoons, hyenas, and seals are also carnivores. Like members of the dog family, wolves breed only once a year. Mating takes place in late winter. The young develop inside the mother for 63 days until birth. Two weeks after they are born the cubs are bigger and stronger. They can know hear and they eyes are open so they can see. They clamber over one another to reach the warmest places under their mother’s body. By the age of three weeks they are able to stand and wobble to the den entrance; they sniff the air and look outside the world. The cubs spent their summer in a grassy spot near their old den. By the fall they are about strong enough to travel with the adults as they roam through their territory in search of food. By the time the female cubs are 2 they are able to mate. Young she-wolf reaches maturity the age at which they can breed, even earlier than their...

...Short Summary Two men are out in the wild of the north. Their dogs disappear as they are lured by a she-wolf and eaten by the pack. They only have three bullets left and Bill, one of the men, uses them to try to save one of their dogs; he misses and is eaten with the dog. Only Henry and two dogs are left; he makes a fire, trying to drive away the wolves. They draw in close, and he is almost eaten, saved only by a company of men who were traveling nearby. The wolves are in the midst of a famine. They continue on, lead by several wolves alongside the she-wolf, and when they finally find food the pack starts to split up. The she-wolf mates with one of the wolves and has a litter of pups. Only one survives after several more famines, and he grows strong and is a feisty pup. They come to an Indian village where the she-wolf's (who is actually half-wolf, half-dog) master is. He catches her again and White Fang, her pup, stays nearby. Soon, she is sold to another Indian, while White Fang stays with Gray Beaver, her master. The other dogs of the village terrorize White Fang, especially one named Lip-lip. White Fang becomes more and more vicious, encouraged by his master. He kills other dogs. Gray Beaver goes to Fort Yukon to trade and discovers whiskey. White Fang is passed into the hands of Beauty Smith, a monster of a man. He fights other dogs until he meets his match in a bulldog and is saved only by a man named Scott. Scott tames White Fang and takes him back to California......

...The dog is classified as Canis lupus familiaris under the Biological Species Concept and Canis familiaris under the Evolutionary Species Concept.[2]:p1 In 1758, the taxonomist Linnaeus published in Systema Naturae a categorization of species which included the Canis species. Canis is a Latin word meaning dog,[19] and the list included the dog-like carnivores: the domestic dog, wolves, foxes and jackals. The dog was classified as Canis familiaris,[20] which means "Dog-family"[21] or the family dog. On the next page he recorded the wolf as Canis lupus, which means "Dog-wolf".[22] In 1978, a review aimed at reducing the number of recognized Canis species proposed that "Canis dingo is now generally regarded as a distinctive feral domestic dog. Canis familiaris is used for domestic dogs, although taxonomically it should probably be synonymous with Canis lupus."[23] In 1982, the first edition of Mammal Species of the World listed Canis familiaris under Canis lupus with the comment: "Probably ancestor of and conspecific with the domestic dog, familiaris. Canis familiaris has page priority over Canis lupus, but both were published simultaneously in Linnaeus (1758), and Canis lupus has been universally used for this species",[24] which avoided classifying the wolf as the family dog. The dog is now listed among the many other Latin-named subspecies of Canis lupus as Canis lupus familiaris.[1] In 2003, the ICZN ruled in its Opinion 2027 that if wild animals and......

Short Stories

...The Four Musicians of Bremen In the story a donkey, a dog, a cat, and a rooster, all past their prime years in life and usefulness on their respective farms, were soon to be discarded or mistreated by their masters. One by one they leave their homes and set out together. They decide to go to Bremen, known for its freedom, to live without owners and become musicians there. On the way to Bremen, they see a lighted cottage; they look inside and see four robbers enjoying their ill-gotten gains. Standing on each others backs, they decide to perform for the men in hope of gaining food. Their 'music' has an unanticipated effect; the men run for their lives, not knowing what the strange sound is. The animals take possession of the house, eat a good meal, and settle in for the evening. Later that night, the robbers return and send one of their members in to investigate. It is dark and he sees the eyes of the Cat shining in the darkness. He reaches over to light his candle, thinking he sees the coals of the fire. Things happen in quick succession; the Cat swipes his face with her claws, the Donkey picks up his hooves and kicks him, the Dog bites him on the leg, and the Rooster crows and chases him out the door, screaming. He tells his companions that he was beset by a horrible witch who scratched him with her long fingers (the Cat), a man with a knife (the Dog), a monster who had hit him with a club (the Donkey), and worst of all, the devil who screamed from the rooftop (the......

Wolves Research Paper

...taiga, and sometimes even urban areas. (www.en.wikipedia.org/wiki/Wolves). Wolves have survived through the ice age. An ancient form of primitive wolf may have originated seven hundred fifty thousand years ago in the eastern part of North America which are thought to be the ancestors of the Eastern Wolf and Red Wolf. Wolves have been in folklore, myths, and cave paintings throughout history. In some cultures wolves were respected and revered, but in other cultures they were feared or looked down upon. Their behaviors have frequently been misunderstood by people. The wolf was once the most widely distributed mammal in the world. Their decline in population and reduction in territory is due to people destroying their habitats and killing them. There were once about fifty subspecies recognized, but the list can be condensed to about thirteen-fifteen general subspecies due to DNA testing, anatomy, distribution, and migration. In 2005, thirty-seven subspecies existed including the dingo and the dog. Some subspecies are extinct or endangered. Some subspecies have been saved by conservation efforts and are being repopulated into the wild through breeding programs. In the following paragraphs, I will discuss several subspecies including the Red Wolf, Mexican Gray Wolf, the Eastern Wolf, and the Arctic Wolf. I will explore their physiology, range, habitat, diet, social structures, reproduction, communication, body language, and behaviors. ......

Call of the Wild

...Evolution, it’s a very interesting topic. Buck (the main character in “The Call of the Wild”) went through evolution in the book. Evolution is the change from one thing to another. Buck has been on a journey of evolution. He has seen his primordial brothers. From the time Buck was dog napped, he has turned fierce and savage. He has learned how to keep warm while sleeping by digging under the snow and sleeping in that hole. He has learned not to fall in a fight or the dogs will pounce on you and shred you to pieces. Buck has killed another dog in rage and competition for leader. Buck has gotten calls (which are wolf howls) from his primordial brothers and runs to the wild and plays with a lone timber wolf. He also has dreams of a primordial man telling Buck to join the wild and hunt for food. He returns home and finds the camp killed by Yeehat Indians, so he kills some Indians, and with no were to go, joins a wolf pack and becomes leader. So you can see Buck has changed from a civilized home dog to a wild vicious wolf pack leader through out the book. He has mastered the ways of the wild and knows how to survive. For example he can now hunt his own food for survival. He can also stay warm while sleeping. Both these examples show that Buck can survive in the wild. He has gone through the process of...

Natural vs Artificial Selection

...Natural Vs Artificial Selection in dogs that has been altered to suit a person’s need Introduction Dogs exist in both wild and domestic set-up whereby they vary in shape and size. This means that there are different breeds of dogs resulting from artificial and natural selection. Each existing species was created separately but they can be modified by the environment. However, these changes are limited hence cannot produce a new species. Artificial selection is whereby a species of a particular plant or animal is modifies by breeders into a distinct breed with unique physical attributes. The offspring obtained from each breeding process may exhibit minimal differences that only a breeder can identify. The aim of this breeding process is to breed an offspring with desired physical attributes, which is then allowed to breed further. An offspring with undesired physical attributes is not allowed to breed. The breeding process is repeated until the small differences observed increase gradually. This represents the process of artificial selection (Venemma). Natural selection represents a similar process that occurs in nature. In a natural setup, organisms normally vary hence reproduce at a specific geometric rate. Survival of these organisms depends on adaptation to the natural environment (Pollan 23). This creates a division whereby organisms that are environmentally suited will reproduce and those not suited will die. This is a resemblance of artificial selection, but this......

Household Dog

...The domestic dog (Canis lupus familiaris)[2][3] is a subspecies of the gray wolf (Canis lupus), a member of the Canidae family of the mammalian order Carnivora. The term "domestic dog" is generally used for both domesticated and feral varieties. The dog was the first domesticated animal[4] and has been the most widely kept working, hunting, and pet animal in human history. The word "dog" can also refer to the male of a canine species,[5] as opposed to the word "bitch" which refers to the female of the species. MtDNA evidence shows an evolutionary split between the modern dog's lineage and the modern wolf's lineage around 100,000 years ago but, as of 2013, the oldest fossil specimens genetically linked to the modern dog's lineage date to approximately 33,000–36,000 years ago.[4][6] Dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "man's best friend" in the Western world. In some cultures, however, dogs are also a source of meat.[7][8] In 2001, there were estimated to be 400 million dogs in the world.[9] Most breeds of dogs are at most a few hundred years old, having been artificially selected for particular morphologies and behaviors by people for specific functional roles.......

Naturalism in Jack London's the Call of the Wild

...Naturalism in The Call of the Wild Jack London was born on January 12, 1876 to a working class family. He had to deal with a hard life from a very young age, but his constant struggling got him through most of the difficulties and by the age of 30, he was internationally famous for his books Call of the Wild (1903), The Sea Wolf (1904) and other successful literay works. Though he wrote passionately about the great questions of life and death and the struggle to survive with dignity and integrity, he also sought peace and quiet inspiration. He wished society to be reformed that he expressed through his writings. His stories of high adventure were based on his own experiences at sea, in the Yukon Territory, and in the fields and factories of California. Similar to a number of writers at that time, he died young, at the age of 40, impoverished (again), sick and suffering from alcoholism. To this day it is still unclear if he the cause of death was accidental morphine overdose or he commited suicide. He as well was a fairly controversial person, so that different authors look at him in various ways: ”The basic law of his thinking was logic. His literary style was the clear, obvious and unmistakable sentences of the beautiful English language. ’The Call of the Wild’ serves as the reference book of English stylistics on Sorbonne. He was the man of facts: not to be afraid of looking inside of the eyes of reality, a great view of life. But Jack London's inner debates......
