Dogs are known to have originated from the gray wolf, with this domestication occurring during the Ice Age, at least 15,000 years ago. But where this happened, and if it occurred in one single location or in multiple places, is still unknown.
Previous studies using the archaeological record and comparing the DNA of dogs and modern wolves have not found the answer.
In their study, published in Nature today (29 June), the researchers turned to ancient wolf genomes to further understanding of where the first dogs evolved from wolves. They analysed 72 ancient wolf genomes, spanning the last 100,000 years, from Europe, Siberia and North America.
