Long science we knew about dog’s, they are regarded as man’s best friend. While there are a lot of things that we can learn from a dog’s behavior, personality, loyalty, companionship, and unconditional love, a recent study done on ancient dogs gives hint that dogs and men entered into a lasting bond after just one try. The study that conducted on the DNA extracts from a 4,700 years old dog skull’s inner ear bone, helps scientists to unveil dog’s origin story.
Dog’s Origin Story From a 4,700 Year Old Ear Bone
Scientists always agreed that the dogs were originated from wolves. However, they were not so clear about since when dogs separated themselves from the wolves. Based on a hypothesis suggested in the last year, dogs were domesticated separately in East Asia and Europe. Recent studies on ancient dogs suggests that dogs took diversion from wolves between 20,000 and 40,000 years ago. As the evolution continued, dogs became genetically distinct eastern and western between 17,000 to 24,000 years back.
The new study on ancient dogs done on a 7,000 year old fossil from Herxheim in Germany, and a 4,700 year old dog from Cherry Tree Cave in Germany helped scientists to believe dog origin as onetime event. Researchers also found relevant data from a 4,800 years old fossil from Newgrange, Ireland.
Researchers like Krishna Veeramah of Stony Brook University in New York suggests that the current study helps science to believe dogs underwent a single domestication event. He also says that it requires some extraordinary evidence to prove that they were domesticated from west and east separately.
While Veeramah demands extra evidence for multiple domestication of dogs, he also says that the new study doesn’t rule out multiple domestication possibilities. While the studies flashed light into dog’s origin story, there are a lot more to learn about the animal and its bondage with humans.
