Credit: Yutahthewolamute / Flickr / CC BY-NC 2.0 Scientists in the United States say many of the small, fluffy dogs seen on city streets today carry more than a cute appearance. They also carry wolf DNA. Researchers announced on Monday that nearly two-thirds of all modern dog breeds tested showed measurable wolf DNA. The results surprised scientists, who expected only…
New studies based on canine genome shed light on these animals
Although they have accompanied humans for thousands of years, their genes still harbor traces of their wild past. Recent research reveals that even the smallest and most domesticated dogs may carry a bit of the wolf within them—often more than anyone suspected.
Almost Two-Thirds of Breed Dogs Have Wolf Ancestry, Study Shows
Although dogs (Canis lupus familiaris) and wolves (Canis lupus) can interbreed and produce fertile offspring, hybridization between the two is far more rare than domestic and wild populations of other species. The post Almost Two-Thirds of Breed Dogs Have Wolf Ancestry, Study Shows appeared first on Sci.News: Breaking Science News.
A new study published on November 24, 2025 reveals that dogs keep genetic traces of wolf in their DNA. Contrary to what might be believed, this is not an ancestral lupine DNA, but rather evidence of a recent hybridization between the two species. Certainly, the dog descends from the wolf. But,
Most dogs have wolf DNA, even chihuahuas.
