Evolutionary origins
All dogs descend from a species of wolf, but not the gray wolf (Canis lupus), like many people assume. In fact, DNA evidence suggests that the now-extinct wolf ancestor to modern dogs was Eurasian. However, scientists are still working to understand exactly what species gave rise to dogs.   

When dogs broke off from their wild ancestors is also a matter of mystery, but genetics suggest that it occurred between 15,000 and 30,000 years ago.

While it’s impossible to say exactly how a wild wolf species became a domesticated dog, most scientists believe the process happened gradually as wolves became more comfortable with humans. Perhaps wolves started down this path simply by eating human scraps. Many generations later, humans might have encouraged wolves to stay near by actively feeding them. Later still, those wolves may have been welcomed into the human home and eventually bred to encourage certain traits. All of this is thought to have unfolded over thousands of years.

Q: Do dogs descend from the gray wolf, Canis Iupus?
A: Dogs did descend from a species of wolf, but not the gray wolf or Canis Iupus, as most people believe. 

Q: Do scientists know exactly what species gave rise to dogs?
A: While scientists are still working to understand exactly what species gave rise to dogs, DNA evidence points to now-extinct Eurasian wolves as the ancestors of modern dogs.

Q: When did dogs break off from their wild ancestors?
A: Although no one knows for sure, genetics suggest that dogs broke off from their wild ancestors between 15,000 and 30,000 years ago. 

Q: How long did it take for wolves to evolve into domesticated dogs?
A: It’s impossible to say exactly; however, the general thought is that it took thousands of years for wolves to evolve into domesticated dogs. 

Q: What do scientists believe the process was of wolves becoming domesticated dogs? 
A: While it’s still quite a mystery, most scientists believe that wolves may have started down the path of becoming domesticated dogs by eating human scraps, then being fed intentionally by humans, and then welcomed into human homes and bred for certain traits.
