By modelling the relationships in and between groups of ancient and modern dogs, the researchers determined that a 10,900-year-old dog from Russia was distinct from later ancient European,...
As far as paleontologists can tell, the very first carnivorous mammals evolved during the late Cretaceous period, about 75 million years ago (the half-pound Cimolestes, which lived high up in trees, is the most likely candidate).
A Brief History of Dogs. As humankind's oldest companion, dogs have been by our side for thousands of years. See how deeply our histories connect and learn how these lovable canines evolved from formidable carnivores to loyal protectors and members of the family.
When they compared the genetics of several well-known breeds of herding dogs, the researchers found that one group of dogs had its origins in the United Kingdom, another from Northern Europe, and yet another group from Southern Europe; the team thought they would be more closely related.
What is a dog? Why do dogs bark? Why do dogs sniff other dogs' rear ends? How are dog years calculated?

Additional evidence suggests that around 15,000 years ago, early dogs moved out of Southern and Central Asia and dispersed around the world, following humans as they migrated. Hunting camps in Europe are also thought to be home to canines known as Paleolithic dogs.

History Dog With The Longest Stay In Shelter's History Finds New Home After 848 Days When Moby first arrived at the Brown County Humane Society in December 2017, he was terrified and confused. Details about his past aren't clear, but rescuers know he was shot at least once and lost his previous home after his owner was arrested.
Anderson Cooper reports on the evolution of dogs from wild wolves to domesticated pets and what this might tell us about human evolution.
The oldest fossil that scientists agree came from a dog, rather than a wolf, comes from a site in Germany called Bonn-Oberkassel and dates back about 14,200 years. But archaeologists have found...
Dogs have been present in North America for at least 9000 years. To better understand how present-day breeds and populations reflect their introduction to the New World, Ní Leathlobhair et al. sequenced the mitochondrial and nuclear genomes of ancient dogs (see the Perspective by Goodman and Karlsson).
In 2021, a literature review of the current evidence infers that domestication of the dog began in Siberia 26,000-19,700 years ago by Ancient North Eurasians, then later dispersed eastwards into the Americas and westwards across Eurasia.
The evolutionary relationships between the species have been studied in the past using morphological approaches, but more recently, molecular studies have enabled the investigation of phylogenetics relationships.
As one of the earliest small dogs, the pug, which hailed from China, was used in Europe from the 1500s onward to shrink other breeds. Thus, pug DNA is part of many other toy and small dog genomes, Parker explains. "This is very exciting!" says Peter Savolainen, an evolutionary geneticist at the Royal Institute of Technology in Solna, Sweden ...
We used jmodeltest2 (v2.1.7) 56 to assess different models of evolution for the ancient and modern dog sequences. The best model was then selected based on the Bayesian information criterion (BIC ...
The dog was the first domesticated species. Yet despite years of research, scientists have struggled to Figure out when, where and how it originated. Recent DNA studies have thrown new light on...
Dec. 8, 2022. In creating modern dog breeds, humans sculpted canines into physical specimens perfectly suited for a wide variety of tasks. Bernese mountain dogs have solid, muscular bodies capable ...
Evolution of the Dog-HUMAN Bond dog [dawg, dog] noun A domesticated canid, Canis familiaris, bred in many varieties. Any carnivore of the dog family Canidae, having prominent canine teeth and, in the wild state, a long and slender muzzle, a deep-chested muscular body, a bushy tail, and large, erect ears. See also canid, the male of such an animal.
These patterns are consistent with the optimization of life history as described by the disposable soma theory of the evolution of aging. The dog breed life span-body size relationship may be the result of the evolution of greater defense against cancer lagging behind the rapid increase in body size during recent breed establishment.

Reviews "This book combines knowledge on dog behavior, cognition, evolution and even covers some societal aspects. As such, it should find an honorable place in the bookshelves of diverse reader audiences, from researchers interested in specific questions in animal cognition to deeply interested pet owners."
Evolution of the Canine Tweet by Brian Lynn on March 28, 2013 in All Things Dog At least 33,000 years ago, humans began the process of domesticating certain members of the gray wolf species. Since that process began, humans have genetically manipulated canines to fill various roles - beginning with tasks that increased means of survival and ...
The very beginning of the human-canine connection. Dogs were one of the very first animals to be domesticated by humans. Research indicates that humans started to domesticate wolves somewhere between 20,000 to 40,000 years ago. There are two main theories surrounding how the connection between humans and dogs started to form.
The dog, man's best friend, is a popular pet. There are hundreds of different dog breeds, each of which is said to have a personality of their own. A study recently completed at the University of ...

The introduction will start on the vehicle side at the end of 2023. "The '75 years of Porsche sports cars' anniversary was the occasion for us to rework this trademark," says Michael Mauer, Vice President Style Porsche.
