Wolves as pets and working animals
Generally speaking, on the basis of their experience, tame wolves are strictly "one-man dogs". They may be confiding and playful with the man who raised them, or even with his whole family, if fed and cared for by them, but they are suspicious and timid in the presence of strangers. They invariably retain certain reactions of wolf nature, as for instance, an incorrigible desire to kill chickens or other small livestock whenever opportunity arises.
Divergent evolution in animals
Another good example of divergent evolution is the domesticated dog and the wolf. Dogs and wolves both diverged from a common ancestor called the Grey Wolf. Dogs and wolves diverged in many places all over the world, each their own separate occasion, rather than just one single isolated event. Then through artificial selection, dogs diverged from the Grey Wolves into the domesticated dog that is known today. To further support divergent evolution of dogs and wolves, genomic research was conducted to compare mitochondrial DNA to indicate the presence of shared ancestry. Taking 162 wolves from various parts of the world as well as 140 dogs of 60 different breeds, it is found that dogs and wolves have shared ancestry by how similar their DNA sequences are. On a macro scale, to support shared ancestry, comparison of the physical characteristics of each animal can be conducted. Dogs and wolves have similar body shape, skull size, and limb formation, further supporting identical genetic makeup and thus shared ancestry. An example of this would be how physically and behaviorally similar malamutes and huskies are to wolves. Huskies and malamutes have very similar body size and skull shape. Huskies and wolves share similar coat patterns as well as tolerance to cold. In the hypothetical situations, mutations and breeding events were simulated to show the progression of the wolf behavior over ten generations. The results concluded that even though the last generation of the wolves were more docile and less aggressive, the temperament of the wolves fluctuated greatly from one generation to the next. Although it can be concluded that evolution may not be happening based on the amount of generations tested, the continuation of generations will become fixated and later support the hypothesis that wolves became more docile to a point where human interaction was capable of existing. By concluding that dogs and wolves are extremely similar physically, behaviorally, and genetically, it is evident that millions of years ago, dogs diverged from the common ancestor called the Grey Wolf and that also dogs and wolves are subject to divergent evolution.
