Origins of the bond between humans and dogs

Origins of the bond between humans and dogs

00:00 - The bond between humans and dogs have been extensively studied due to its unique nature. This special relationship can be traced all the way back to when humans first started living in groups.
00:17 - 1 -the theory:
An early domestication theory suggests that the symbiotic, mutualistic relationship between the two species started when humans moved into colder Eurasian regions.
00:29 - 2 - First reports:
Paleolithic dogs first began to appear at the same time, developing shorter skulls and wider braincases and snouts compared to their wolf ancestors. The shorter snout eventually led to fewer teeth, which may have been the result of humans’ attempts to breed aggression out of dogs.
Ancestors of the modern dog enjoyed plenty of benefits from living around humans, including improved safety, a steady supply of food, and more chances to breed. Humans, with their upright gait and better color vision, also helped in spotting predators and prey over a larger range.
It has been hypothesized that humans in the early Holocene era, around 10,000 years ago, would have chosen wolf puppies for behaviors like tameness and friendliness towards people.
These puppies grew to be hunting companions, tracking and and retrieving wounded game as their human packs settled in Europe and Asia during the last Ice Age. The dog’s heightened sense of smell greatly assisted in the hunt, too.
01:27 - 3 - Help welcome:
Aside from helping humans hunt, dogs would have proved useful around the camp by cleaning up leftover food and huddling with humans to provide warmth. Australian Aborigines may have even used expressions such as “three dog night”, which was used to describe a night so cold that three dogs would be needed to keep a person from freezing.
These early dogs were valued members of forager societies. Considered superior to other types of dogs back then, they were often given proper names and considered part of the family.
Dogs were often used as pack animals, too. Some studies suggest that domesticated dogs in what is now Siberia were selectively bred as sled dogs as early as 9,000 years ago, helping humans migrate to North America.
The weight standard for these dogs, 20 to 25 kg for optimum thermo-regulation, is found in the modern breed standard for the Siberian Husky.
While it may seem like humans valued dogs in a merely utilitarian sense, studies suggest that humans have formed emotional bonds with their canine companions since the late Pleistocene era (c. 12,000 years ago)..
02:20 - 4 - Friendship until the end of life:
This is evident in the Bonn-Oberkassel dog, which was buried with humans even though humans had no practical use for dogs in that particular period.
The Bonn-Oberkassel dog would have also required intensive care for survival, as pathology studies hypothesize that it suffered from canine distemper as a puppy. All these suggest the presence of symbolic or emotional ties between this dog and the humans with which it was buried.
No matter the exact history of dogs’ domestication, dogs have learned to adjust to human needs. Dogs became more respectful of social hierarchies, recognized humans as pack leaders, became more obedient compared to wolves, and developed skills to effectively inhibit their impulses. These animals even adjusted their barking to communicate with humans more efficiently.
