In ancient Egypt, dogs were thought to possess godlike characteristics (Vanacore). Brian Hare says that dogs self domestication, and it happened because a population of wolves one day spotted an easy meal—the garbage lying around where the humans were. He also said that if we can figure out how to dog was domesticated and evolved, then we can figure out how it happened to us humans (Hare)
As surprising as it may seem, the canine reproductive system is a subject that has not been extensively researched. The research involved in the cloning process is uncovering all sorts of information on the canine reproductive system. The third goal is to enhance the reproduction of endangered species. If Project Missyplicity is successful at cloning dogs, the possibility of cloning other species becomes more and more probable. The forth goal is to replicate specific exceptional dogs.
Wolves are scavengers as well as hunters and may have been some of the first animals to discover this squander treasure (Horowitz, 2009). The least fearful of these wolves became increasingly undaunted by the presence of the unfamiliar humans. Together the two species began to tolerate one another through prolonged encounters until finally, humans began taking in a few pups as “pets” or, in times of hardship, “food.” Eventually, our ancestors began intentionally breeding these “domesticated” wolves to serve as assistant hunters and protectors (Horowitz, 2009). We can only surmise that the functionality of these domestic wolves served a great purpose; for what other reason would justify letting a meat-eater into one’s home? It would be difficult to provide provisions for such an animal and if one were unsuccessful, they befall a risk of becoming their pet wolf’s next meal.
Geographic origin of dog domestication as somewhere in southeastern Asia, and Chinese Native dogs most closely related to ancestral dogs was a consistent finding among researchers (Wang et al. 2013). Overall, the initial domestication process of dogs involved rapid brain gene expression evolution due to artificial selection, and breeding programs had insignificant amount of selection for gene expression in the brain (Yan et al. 2013).The time of divergence between ancestral dog and wolf was not consistent between findings. Future research could focus on DNA testing of ancient dog-like canines to determine a more accurate time for divergence.
They most likely would have killed those types of wolves or left them behind to fend for themselves. The hunters would have chosen semi-tame wolves and those with the most desirable traits and abilities and bred the two together, repeating the process until what resembled a dog today.

The common dog will always trace its roots back to the single wolf cub that was taken in by humans so long ago. Works Cited Beltz, Pat.
Restoring Wolves to Yellowstone In his book, Never Cry Wolf, Farley Mowat tells an Inuit tale, saying that in the beginning, caribou were created for humans to hunt. However, humans “hunted only the big, fat caribou, for they had no wish to kill the weak and the small and the sick,” creating a weak population of caribou. The creator then made wolves to eat the sick, weak, and small caribou, creating a natural health and balance to the earth (124). Humans have traditionally seen wolves as a competitor and a danger, but these misconceptions can now be put to rest. Because wolves regulate the carrying capacity, preserve the health of herds, and complete the ecological cycle in a balanced system, they must be restored to Yellowstone.
If other animals, like silver foxes, domesticate similarly to the way a dog evolves then why were dogs domesticated rather than a different species? The topic of dog domestication poses many unanswered questions. When and where did wolves first interact with humans? How did these two different species interact and why? Even with the species barrier, humans and wolves have a lot in common.
From antiquity, wolves have been a central part of human existence. From Eurasia to North America, wolves have been interacting with humans for ages.

(Dogtime, 2009) Eventually humans would see that certain individuals were better for certain tasks than others. For instance one individual that was a very fast runner, but rarely barked made for a good hunting companion. However, another that wasn't good at running, but would bark at strangers made for a good guard dog. People would see these characteristics and would specifically breed individuals to concentrate certain traits, Such as breeding two dark-haired wolves to get dark-haired offspring, or two large and intimidating wolves to get large intimidating offspring. With these specific breeds being created, the offspring of the various pairings would either have very similar characteristics between one a... ... middle of paper ... ...helped widen the gene pool within the species.
Many forms of dog food are meat based, though, similar to the carnivorous diet of the gray wolf. Beyond commercial store-bought food, domesticated dogs do, however, form natural instincts that tend to have them go after smaller prey at times. Communicative patterns were also handed down from gray wolves to dogs, as behaviors dogs have inherited from wolves include "a complex communication system ranging from barks and whines to growls and howls" (Basic). Dogs commonly display barking to show a variety of emotions and barking i... ... middle of paper ... ...of wolves, and have evolved from the gray wolf species specifically. This evolution began about 10,000 years ago when the first dogs became domesticated.
