What is the ancestor of the dog? - in detail
The ancestor of the modern dog, Canis lupus familiaris, is the gray wolf (Canis lupus). This lineage can be traced back approximately 15,000 to 40,000 years ago when wolves began to diverge from their wild ancestors. The process of domestication started as early humans and wolves formed mutually beneficial relationships. Over time, selective breeding by humans led to the development of various dog breeds that we see today. This transformation involved changes in both physical characteristics and behavior, adapting dogs for specific roles such as hunting, herding, guarding, and companionship. The domestication of wolves into dogs is considered one of the most significant events in human history, shaping the evolution of both species and their interconnected lives.
