    Washington: According to a new study by an international group of geneticists and archaeologists of the Francis Crick Institute, have discovered that the ancestry of dogs can be traced to at least two populations of ancient wolves. The study revealed the answer to the most asked questions about human prehistory by stepping closer to uncovering the mystery of where dogs underwent domestication. The findings of the study were published in the journal Nature. 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, 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. The remains came from previously excavated ancient wolves, with archaeologists from 38 institutions in 16 different countries contributing to the study. The remains included a full, perfectly preserved head from a Siberian wolf that lived 32,000 years ago. Nine different ancient DNA labs then collaborated on generating DNA sequence data from the wolves. By analysing the genomes, the researchers found that both early and modern dogs are more genetically similar to ancient wolves in Asia than those in Europe, suggesting a domestication somewhere in the east. However, they also found evidence that two separate populations of wolves contributed DNA to dogs. Early dogs from north-e ...
