Ancestors of the ferocious wolf, dogs were the first lovable companions of human kind. The oldest fossil evidence of dogs comes from 14,000 years, but their DNA suggestions that dogs have persisted in maintaining their role as a companion from much earlier. Scientists hypothesize this unique relationship flourished through unintentional or intentional selecting for behavior.
Scientists puzzled over why dogs’ anatomy, physiology, and behavior had changed so drastically from their ancestors. For example, domesticated animals share numerous traits that their wild counterparts do not possess, such as wavy hair, droopy ears, and a willingness to be near humans. They wondered what was responsible for the plethora of changes.
In 1957, the experiments had already begun by collecting silver foxes previously bred for fur farms. To test the hypothesize and ensure tameness was a result of

The foxes breeding patterns changed; they become sexually mature a month earlier, mated out of season, and had on average one more offspring per litter. They also retained juvenile traits, such as floppier ears, shortened legs, tails and snouts, changes in coat color, and wider skulls. Simply put, they appeared “cuter” without the scientists directly attempting to alter their appearance.
Fifty years later, and the experiment is ongoing to better understand man’s relationship with dogs. When put to the test, scientists were able to domesticate foxes in a human lifetime.
By 2005, it was reported nearly all foxes were playful, friendly, and respond to pointing cues almost as well as dogs. Individual foxes can already sit and fetch on command, but the scientists are waiting until they see this on a larger scale. Currently, some foxes are even sold as pets to fund the program.
While the goal of the experiments hasn’t changed, the understanding of evolution and genetics has. Will foxes join dogs as man’s best
My animals name is Foxzilla and it was discovered by Enmanuel Aponte. The animal was named after Godzilla. When first discovered scientist weren’t sure what it was. According to the scientist at the time the animal had a similar body of gazelle, similar legs of wolf, and a similar head of a fox. When they saw that they know it was a mutation. They found the Foxzilla in a cave taking sheltered because at the time it was raining. The scientist know that foxes were friendly to humans, but weren't sure if the animal would react if they moved on it to take photos. The scientist need a plan to take the Foxzilla into the lab to exam it before releasing it to press and the world. Luckily at that time the scientist had a big cage to capture the Foxzilla and they did so.
Humans and dogs have long shared a bond that was based on function. Early dogs that were the least valuable and useful did not make it into today’s time. On the other hand, the most valuable and helpful of dogs remained and created others like them. Ultimately, breed predecessors were produced by breeding the best hunters to the best hunters and the best guards to the best
Another reason why dogs and humans changed over time because they started caring
For millions of years dogs have remained a constant companion of man. Bred from the aggressive and formidable Gray Wolf tens of thousands of years ago the domestic dog now lives in many homes across the world. Where in the far distant past the domestic dog was bred as a guard animal, a beast of burden, and even a food source the dogs of today are bred for a far more endearing purpose-companionship and love. Finding a pet dog that is more of a joy than a chore is necessary when asking: How much is that puppy in the window?
A long time ago, dogs were once wolves, and they worked for humans. Over the millennia, wolves have evolved into dogs, and dogs have become friendlier. The way wolves have changed over time into dogs have been very noticeable. Although, the arctic grey wolf didn't turn into Cavalier King Yorkshire Terrier overnight. The reason the two, dogs and wolves, have changed are plentiful due to the changing relationship between humans and dogs. It cannot be denied.
To begin, animals have been a part of human society for thousands of years. According to the article “Assistance Dogs: Learning New Tricks for Centuries”, man began taming wolves as far back
If a survey, about what domesticated animal is good for future pet owners, was conducted today, I can bet that most pet owners would say that they prefer domesticated dogs as a pet. Dogs have been man’s best friend since the dawn of homosapiens, approxitmately 15,000 years ago. If humans and dogs have overtime created this bond, then how was that connection created and how strong is it? In Melissa Chan’s article “The Mysterious History Behind Humanity’s Love for Dogs” from the August 25, 2016 issue of TIME Magazine, she successfully implements the rhetoric of logos, and pathos throughout her article to solve the mystery of the bond between humans and dogs.
The grey wolf has been transformed into what we, today, call a dog. After years of traveling with humans, the wolf began to change and became adapted and tame enough to socialize with humans. The environment it was placed into was one of the causes for change, and another was the role it played for humans.
How did it all began? The relationship between dogs and humans have changed over time. Dogs were the first animals that have been domesticated by humans. Dogs have been with Humans from the beginning. They have been evolving with humans for almost 32,000 years.
Nobody knows exactly when dogs were domesticated there is so many different showings of when dogs were domesticated but the latest would be where it says 32,000 years ago. The domestication of cats and dogs or any animals come from humans and animals living so close to each other in close quarter communities. Genes during domestication overlaps with the genes from humans, the same kind of genes are for digestion, metabolism, neurological process and cancer according to population genetics. So humans and animals both was domesticated from the same genes. Human and animals are a lot alike. “Biologist Raymond Coppinger has another idea, the wolves domesticated themselves he suspects the process would have begun at the end of the last Ice Age approximately 15,000 years ago” (“What Caused The Domestication Of Wolves”). Coppinger believes in “flight distance” which is a behavioral characteristics that transformed the wild dogs to the modern dog
It can be argued that along with cats, dogs were one of the first animals to become domesticated. For approximately 10,000 years humans and dogs have more than co-existed, they have developed a special bond unlike any other animal has developed with us. Today hundreds, if not thousands of breeds of dog exist. Although this fact remains true, all dogs belong to the Canis Familiaris family within the animal kingdom. Despite any tamed, domesticated, or docile tendencies, all breeds of dogs have traits that are derived from their wild ancestors and to this day many of those traits still exist and in fact, are quite important to the dog’s survival and mating techniques. Some of the more prominent survival tactics include digging, burying, being
Dogs were the first animal, and the only large carnivore, to be domesticated. in both appearance and in both Dogs are not tame wolves, but how they became these unique companions to people is still being debated.
Josh Gelman 10/2/12 Science Research Paper Domestication of foxes in Russia In the world people have been domesticating animals for amusement, comfort, and for them to be mans best friend. Now a new mans best friend comes to thought; to domesticate foxes. In Russia a Soviet geneticist Dmitry K. Belyaev started the fast pace domestication of foxes. Up to 50,000 foxes used through time people are getting close to the domestication of foxes, although the process was very detailed; with genetic science, to identify how phenotypes change from experiments, and how the fox’s will change their behavior.
“A dogs sense of smell sometimes out perform X-Rays and CT scans at detecting cancers at an early stage by simply smelling a persons breath or urine.” Everyone is able to breed a dog to function in many different ways and for many different reasons. Mow explains how this is possible through his short movie Science of dogs. “Because of intensive selective breeding by cross breeding different breeds for different distinctive types of physical appearances and behavioral attributes; you will soon create the dog you were looking for and it will also have a consistency of creating the same breed of dog by creating a new genetic code in the dogs DNA”. For example there is one breed of dog that has the best sense of smell in the entire world and they were created for one job and one job only. Klim Sulimov explains what dog this is and how it was formed on the Science of Dogs, “The Sulimov dog has the best sense of smell in the whole entire world, and they were successfully created to identify explosives, he bred a Jackal with a Lapland Herding Hound, a Reindeer Herding Hound, a Fox Terrier, and a Spitz. Creating a dog that is highly trainable dog and a superior snout”. All these hybrid breeds are so successful because of how the dogs DNA is formed. The discovery of deciphering the dog genome was discovered by the Researchers at the National Institutes of Health on The Science of Dogs “Every piece of DNA is made up of four different chemical components
Since the 1950’s Russian scientists Dmitri Belyaev and Lyudmila Trut have run an experiment on the selective breeding of foxes. Each and every generation the foxes was cautiously observed. Searching for only the most amiable among them, the scientists hoped to engineer a fox that didn’t just tolerate human contact, but also craved it. The animals were organized by how friendly they were, then bred with similarly classified foxes. The scientists repeated this process on thousands of foxes across decades, slowly working closer and closer to their final goal: domestication. During the species’s change to becoming companions, the foxes’ “friendly gene came attached to some other physical genes that made the foxes look like other domestic animals:
