Abstract
Scientists recently discovered an 18,000-year-old preserved canine puppy. Could this incredible discovery be the earliest dog ever uncovered? And could he help us understand more about the origins of dogs and wolves?
We studied 70 ancient wolf specimens and found some possible answers. Dogs appear to have come from two separate ancient wolf populations. We believe that there are two possibilities for how this could have happened. By analyzing the DNA of ancient wolves, we can better understand wolves and dogs who live today!
