Recent molecular evidence shows that dogs are descended from the gray wolf, domesticated about 130,000 years ago. But if they all share a common ancestor, why do toy poodles and Great Danes seem to have little in common? Years of selective breeding by humans has resulted in the artificial “evolution” of dogs into many different types.
Because of the growing concern about health problems and the availability of powerful methods to hunt genes, scientists are hard at work on the “dog genome project.” As with the Human Genome Project, the goal is to locate and map canine genes, particularly those that play a role in disease.
But DNA analysis published in 1997 suggests a date of about 130,000 years ago for the transformation of wolves to dogs.
Where did dogs evolve from?
Thanks to DNA, we can see that dogs evolved from wolves somewhere between 19,000 and 32,000 years ago in Europe, but the genome of living dogs shows that the split took place in Asia around a thousand years earlier.
How was a dog created?
Dogs most probably evolved from wolves at a single location about 20,000 to 40,000 years ago, a study suggests. Previously, it had been thought that dogs were tamed from two populations of wolves living thousands of miles apart. … The ancient canines share ancestry with modern European dogs.
How did dogs come to earth?
Scientists generally agree that dogs emerged from wolves to become the first domesticated animal. Their wolf ancestors began to associate with people, maybe drawn by food in garbage dumps and carcasses left by human hunters. … Over a very long time in this human environment, wolves gradually turned into the first dogs.
What was the first breed of dog?
The world’s oldest known breed of domesticated dog is the saluki, believed to have emerged in 329 BC. Saluki dogs were revered in ancient Egypt, being kept as royal pets and being mummified after death.
But the ancient origins of an animal that is an honorary member of many human families has remained in doubt: We still dont know where dogs came from.
Dr. Savolainen has argued strongly, with limited support from other researchers, that dogs originated in East Asia, which, he noted, fits with at least half of the papers conclusion. Dr. Larson and Keith Dobney of Liverpool University found that wild boars were domesticated twice, once in China and once in Anatolia, part of modern Turkey.
For the new study, Dr. Larson and Dr. Frantz obtained DNA sequences from 59 ancient dogs and a complete genome from a 4,800-year-old-dog fossil found at Newgrange, a well-known archaeological site in County Meath, Ireland. Although the new explanation may seem to complicate an already tangled discussion, Dr. Larson says it actually clears up confusion by explaining two competing ideas, the western and eastern origins of dogs.
