Wolf to Woof: Siberian Husky
Transcript of Wolf to Woof: Siberian Husky
Some features that it has to help it in its cold environment (and to help it work at its best in hauling sleds in harsh conditions) include: 1:
A thick double coat that can resist temperatures as low as -58 to -76 degrees Fahrenheit, 2:
A great amount of strength to help them haul heavy loads mounted on sleds and carts, 3:
The ability to withstand long work days under harsh conditions with little food while traveling far distances at up to 40 miles per day. Physical Appearance 4: Large feet with a considerable amount of hair to keep warm and help grip on ice. Despite these advantages given, this breed can still gain certain ailments from inheritance. These problems include: Parti-eyes (eyes that are half-blue or half brown), Seizures, as well as congenital laryngeal paralysis, Gastric disease and erosion (in racing dogs), And as well as bronchitis and ulcerations. Siberian Husky
History and Breeding The Siberian Huskies and their family are considered one the oldest breeds of dog today. They were descended from the Canadian Eskimo Dog. During their time, they were selectively bred for speed, strength, and endurance. Their first use was with the Eskimo people, when the huskies' purpose was for pulling sleds for transport. Eventually, they made it into public use as sled dogs for transport and hauling during the Alaskan Gold Rush. Since they were specially built for frigid environments and pulling sleds and wagons, the Siberian Huskies were very effective in the field. They also became popular in racing, as they were more compact, were much faster, and could endure harsh conditions longer than other dog breeds. Later, they were also used for important occasions, like WW2 and expeditions in Antartica. Their breed was finally recognized in 1930. Though similar, the processes of ARTIFICIAL SELECTION and NATURAL SELECTION have notable differences. Both processes involve evolution and variation, but these two processes occur in different ways. Artificial selection involves taking the best offspring with the most desirable traits and letting them make their own offspring. Meanwhile on the other hand, natural selection is when animals that are better adapted to their environment get to make offspring of their own with the traits they have. Also, selective breeding is one method of artificial selection, the former of which as its own variants. THE END! Thanks for Viewing! Bibliography "Siberian Husky Information." Dog Breed Info Center.

Natural Selection Artificial Selection Both No humans are involved in
this process All critters involved must survive on their own;
there is no human assistance There are other factors involved, like overproduction, variation, and competition. The results are undetermined and occur
randomly; desirable traits may or may
not show. Humans are involved and
determine how it goes Competition is not involved in the process. Offspring with desirable traits are
allowed to live on and make their own
offspring. Today, we all have had dogs at our side since long ago. We used them for many purposes, like tracking, work, hunting, or as simply companions. Many people even have one. However, have you ever wondered just how they came to be? Just how did man's best friend go from a wild wolf to the many dog breeds we have now? How did it ever go from wolf to woof? That is what I will be explaining in to you.
There is an entire plethora of types of purebreds and mutts out in the world, but one such example is the Siberian Husky, a work dog used for pulling sleds and cargo.
I will explain: By: Edwil Bisnar Selected Breed: Siberian Husky Inheritance Problems Natural & Artificial Selection: Similarities & Differences or bi-eyes (two different colored eyes), Artificial Selection has its own
variations and there are different
About the physical appearance and special traits of the Siberian Husky, About how it was developed into the utility dog it is now, And the difference between natural and artificial selection, and how it relates to breeding. Both can result in new species Variation and overproduction are also involved regardless of method As they are different, artificial selection is more preferred, and
more effective, than natural selection since in artificial selection, people can effectively make offspring with desirable traits without having to deal with loss of any of the parents while they are growing. Also, it's easier to use the alternate methods of artificial selection, like selective breeding, inbreeding, and hybridization, to make a dog with desirable traits or a new but similar species.
