When were the dogs born? - in detail
The origins of the domestic dog, Canis lupus familiaris, are a subject of intense scientific interest and debate. While it is clear that dogs descended from wolves, pinpointing the exact time of their domestication has proven challenging due to the complexity of the process and the lack of fossil evidence. However, recent advancements in genetics and archaeology have provided valuable insights into this intriguing question.
Genetic studies suggest that dogs were first domesticated between 15,000 to 40,000 years ago. A landmark study published in Nature Communications in 2017 analyzed the DNA of ancient and modern wolves and dogs, concluding that the two species diverged around 36,900 to 41,500 years ago. This genetic data aligns with archaeological findings that indicate the earliest known remains of domesticated dogs date back approximately 15,000 years.
The exact timing and location of dog domestication are still topics of ongoing research. One prominent theory proposes that wolves were initially attracted to human settlements by discarded food scraps, which led to a gradual process of co-evolution. Over time, these wolves adapted to living alongside humans, developing physical and behavioral traits that distinguished them from their wild ancestors.
Moreover, the geographical spread of dog domestication is also under scrutiny. Some evidence suggests that dogs may have been first domesticated in multiple regions independently, rather than in a single location. This hypothesis is supported by genetic studies showing distinct lineages among different breeds and populations.
In summary, while the precise date and circumstances of dog domestication remain elusive, recent scientific advancements have brought us closer to understanding this pivotal moment in human-canine evolution. The process likely occurred over thousands of years, involving complex interactions between humans and wolves that ultimately gave rise to the diverse array of domestic dogs we know today.
