Nov 3, 2021 · The connection between human and dog runs deep. Early signs of domestication date back to 33,000 years ago and unambiguously domesticated dogs are common in the archaeological record beginning 15,000 years ago. The pairing makes for a striking case in coevolution — no other species has been so thoroughly integrated into human society.

Oct 29, 2020 · As early as 11,000 years ago, there were already five distinct dog lineages; these gave rise to canines in the Near East, northern Europe, Siberia, New Guinea, and the Americas, the team reports today in Science. Because dogs had already diversified so much by that time, "domestication had to occur long before then," Skoglund says.
May 14, 2013 · The study shows that dogs split from gray wolves about 32,000 years ago, and that since then, domestic dogs' brains and digestive organs have evolved in ways very similar to the brains and...

The history of dog evolution is often depicted in two stages. First, from an extinct species of wolves to modern-day gray wolves and dogs, and the second from dogs to breeds. A 2017 study published in Naturefound that dog ancestors lived 40,000 years ago, who split into the present-day wolves and dogs. The European and Asian groups of dogs divided ...
The journey from wild wolves to tail-wagging companions is still marred with mystery with new theories and studies revealing different aspects of a dog's evolution as man's best friend. But broadly there are two popular notions. According to Susan Crockford, an anthropologist and zooarchaeologist with University of Victoria in Canada, the first rea...
The association of wolf-dogs and humans began between 10,000 and 30,000 years ago, but there is no single evolutionary chain in dog's history as a species that can pinpoint to the oldest domestication. From southern China to Mongolia to Europe, genetic studies point to several regions and time when humans found companionship in dogs.
By assessing the genome of 1,346 dogs across 161 breeds, Heidi Parker, a dog geneticist at the U.S. National Institutes of Health found an evolutionary timeline on how humans bred dogs as per their needs, like herding or guarding. She told The Verge, "Each time we come up with different changes into our own sort of society and the way we live, then...
Being the oldest domesticated animals, humans and dogs have the longest shared history. A 2013 study published in Nature Communicationsproved this is true at the genetic level, too; several groups of genes in humans and dogs evolved in parallel for thousands of years. This includes the genes related to digestion, food, neurological process, and dis...
It is widely believed that ancient dogs traveled with humans across the Bering Strait, to carry things and defend against predators. But with the arrival of the Europeans with their own dogs, the native American dogs disappeared entirely. Dog geneticist Heidi Parker suggests though that the Peruvian hairless dog, the Xolo, and the American hairless...
A great illustration of the earliest mutually beneficial relationship between dogs and humans and how it evolved with time is the Samoyed bred by the Samoyede. The Samoyede were nomads who had traveled from Asia to Siberia thousands of years ago. The dogs that traveled with them were the Samoyed, the same breed we know today. These dogs were bred s...
The earliest traits for which dogs were selectively bred included hunting, herding, and guarding. Two ancient examples of such dogs are greyhounds and mastiffs. In Egypt, greyhounds were revered as much as the pharaohs and used as hunting animals. Mastiffs, on the other hand, have been around for thousands of years in various civilizations across E...
One of the first breeds to emerge after the domestication of dogs began was the East Asian breed chow chow. Chow chows are protective of their owners and have unusual features like a blue tongue and 44 pairs of teeth instead of 42. It is believed that they were bred from native Chinese dogs around 11,000 to 9,000 years agoat the same time as agricu...
The gradual shift of dog breeds from being hunters and herders to working dogs can again be traced to the cold northern regions with the example of the Siberian husky. This tough breed was originally bred as companion dogs by the Chukchi people. But as life became tougher in the sub-zero conditions, the people needed to travel more, and the dogs to...
Nov 4, 2020 · November 4, 2020. A genetic analysis revealed that by the end of the last ice age—around 11,000 years ago—there were a least five distinct lineages that gave rise to dogs in New Guinea, the...
Aug 23, 2010 · As early as the work of Zeuner (1963), theorists pointed out that the human-dog relationship was not like other dynamics of domestication, and that dogs themselves may have initiated a process that led to their eventual domestication by living commensally, or following along with humans and slowly adapting to life with our type, rather than by ...
