Various splits in genetic evolution across history has led experts to believe that the Taymyr wolf and another number of extinct wolves were the original ancestors of the pet pooches that we have today. The DNA of modern doggies today is, therefore, likely an origin of various splits in ancestral DNA, some of which are now extinct. We need to venture back a good 60 million years to figure out the evolutionary timeline of our four-legged friends and to visualise what they were like before they became household companions.
A good place to start is with the Miacis - which is a far cry from a wolf at this point in evolution. This animal, native to North America, existed in the Paleocene epoch. Walking on the soles of its feet and with shorter legs than the dogs we know today, it had the distinctive carnivorous teeth that we recognise in dogs today.
The following stage of evolution is believed to have taken place 35 million years ago, with the fox-like Leptocyon. This animal had evolved to walk on its toes, allowing it to run faster.
This animal was more intelligent, with a larger brain than its predecessors, and looked more like a dog. Some of the most basic doggy instincts were established millions of years ago — for instance, this creature could remember its family members, which was the beginning of developing a pack mentality in dogs.
Wolves then followed about million years ago; they had developed many advantageous canine instincts such as walking on four hind toes to hunt down their prey, and a strong pack mentality. Around one million years ago, the final stage in canine evolution was wolves and jackals, which could be found in Eurasia. This marked the beginning of the early wolf and are the closest to what we know before dogs were domesticated. The pooches and puppies that we know today are a country mile from their predatory wolf ancestors.
Domestication has largely diminished any instinct or need to hunt, and so domestic dogs need their human companions more than we think.
Just imagine a world where dogs would have to return back to the wild and live without humans: no more trips to the vet thanks to dog insurance , no food and snacks delivered periodically without any effort, and no cuddles in the comfiest of spots.
Would it be possible, we wonder? Even cats could probably do well if they were released into the wild, as they have retained their drive to hunt and their independent nature. While dog training methods are based on the behavioural patterns of wolves, dogs have moved on considerably from wolves, and have developed more human-like habits and diets than their ancestors.
Living alongside dogs has created an evolutionary union between us and them unlike no other — so looking after them should be our number one priority. The origin of our favourite family pets continues to be mired in scientific debate, but what we do know is that we have thousands of years to thank for the wonderful bond that we share with them. What better way to take care of your favourite pooch than to take out dog insurance?
Let us help you get a quote today so you can take lifelong care of your beloved friend. Get Your Quote. Are all dogs descendants of the wolf? So, when did the domestication of dogs begin? Maria Lahtinen of the Finnish Food Authority in Helsinki and her colleagues suggest that the key may have been a surfeit of meat. Dogs were domesticated when ice sheets covered much of northern Eurasia and the climate was colder than today.
During this time, humans and wolves would have competed for food, as both are top predators. However, wolves can survive on nothing but lean meat — which contains protein and little else — for months.
In contrast, humans cannot. There are limits to how much protein our bodies can handle, so we have to eat other food groups such as fat as well. Canine companions spontaneously develop some of the same diseases that plague humans, such as cancer, heart disease and obesity.
Researchers hope that dogs might shed light on how these conditions develop, ultimately leading to treatments that could help both species. One such study is the Morris Animal Foundation Golden Retriever Lifetime Study that is gathering lifestyle and genetic information on more than 3, golden retrievers.
This groundbreaking project will provide a wealth of new information that will help identify risk factors for canine diseases, including many cancers. This study also has many translational components that may inform human health risk factors. Morris Animal Foundation was one of the first organizations to recognize the potential of genetic research not only in dogs, but in cats, horses and llamas.
By unlocking the genetic code, Foundation-funded researchers have discovered new therapy targets, genetic abnormalities underlying disease, and greater understanding of the problems afflicting our beloved companions.
