The dog comes from the wolf. At least, that is what the main investigations maintain, which conclude that they arose from wild wolves
What is not so clear is when and where these wild wolves came from. There are lines of research that maintain that the process of domestication of dogs it started ago more than 15,000 years and not as such, but as a result of the fact that lobos In ancient times they began to get closer to human settlements, when they began to lose their fear of men. That is, in reality it was not the man who domesticated the dog, but the relationship between the two it appeared naturally and strengthened over time.
Other studies maintain, for their part, that the first animal domesticated by humans was the Southeast Asian wild wolfand that this occurred 33,000 years ago.
The dog of the year 12,000
Taking these data into account, scientists and geneticists They have analyzed what dogs could be like in 10,000 years. Basepaws, a Californian company that analyzes pet genes -especially dogs and cats- to improve their health and provide them with personalized food and medical treatments, try to discover how our pets will adapt to the changes expected in the coming millennia. They have also made use of the artificial intelligence to show what these changes would look like.
In principle, both dogs and other pets and other animals must evolve including adaptations to the environmentthat is, they should develop characteristics that allow them to survive in specific environments, either due to extreme climate changes or to the colonization of new habitats.
Because of these adaptations, dogs’ body shape and structure could evolve to adapt to different environmental conditions, such as changes in gravity, temperature, or atmospheric pressure. Their food sources could also change, which could lead to adaptations in the diet and, as a consequence, in the dogs’ physiology.
