Most dogs have wild wolf DNA, study finds
A study of 2,693 dog genomes reveals that most domesticated dogs have some wild wolf DNA, with larger breeds having more.
Why it matters
- Shows interbreeding between dogs and wolves is more common than thought.
- Helps understand dog domestication and genetic diversity.
By the numbers
- 2,693 dog genomes analyzed.
- Most dogs have some wild wolf DNA.
- Chihuahuas: 0.2% wolf DNA.
- St. Bernard: 0% wolf DNA.
The big picture
- Dogs and wolves share a common ancestor and have interbred throughout history.
- Wolf DNA may have helped dogs adapt to various environments and roles.
What they're saying
- Some commenters surprised by lack of wolf DNA in certain breeds.
- Real-world examples of dog-wolf hybrids exist.
Caveats
- Study relies on genetic analysis, which has limitations.
- Exact extent of wolf DNA not fully detailed.
What’s next
- Further research could explore genetic contributions of wolf DNA to dog breeds.
