When did dogs appear on Earth according to Wikipedia? - briefly
Dogs, as we know them today, are believed to have diverged from wolves around 15,000 to 40,000 years ago. This domestication process likely began when wolves started to associate with human hunter-gatherer groups, leading to a mutualistic relationship that eventually resulted in the domesticated dog.
When did dogs appear on Earth according to Wikipedia? - in detail
The domestication of dogs is a subject of significant interest in the fields of biology, archaeology, and anthropology. According to Wikipedia, the timeline of when dogs appeared on Earth is a topic of ongoing research and debate among scientists. The most widely accepted theory suggests that dogs were domesticated from gray wolves (Canis lupus) at least 15,000 years ago, although some evidence indicates that this process may have begun even earlier.
The earliest archaeological evidence of dog domestication comes from a site in Siberia, where the remains of a dog were found buried alongside human remains, dating back approximately 33,000 years. This discovery suggests that the relationship between humans and dogs may have started during the Paleolithic era. However, genetic studies provide a more nuanced understanding. These studies indicate that the domestication process likely occurred gradually over thousands of years, involving multiple populations of wolves that were independently domesticated by different human groups.
The genetic divergence between dogs and wolves is estimated to have occurred around 15,000 to 40,000 years ago. This period aligns with the time when humans were transitioning from nomadic hunter-gatherer lifestyles to more settled agricultural societies. During this transition, wolves that were less fearful of humans and more tolerant of their presence would have had a survival advantage. Over generations, these wolves would have been selectively bred by humans for desirable traits, leading to the development of the modern dog.
The process of domestication involved significant changes in the behavior, appearance, and genetics of wolves. Over time, these changes resulted in the diverse array of dog breeds that exist today. The domestication of dogs is considered one of the earliest and most significant examples of animal domestication by humans, marking a pivotal moment in the history of human-animal interactions.
In summary, while the exact timing of when dogs first appeared on Earth is still a subject of scientific inquiry, the available evidence points to a gradual process of domestication that began at least 15,000 years ago, with some indications suggesting an even earlier start. This process involved complex interactions between humans and wolves, leading to the development of the domesticated dog as we know it today.
