The Evolution Of Dogs

“I like a bit of a mongrel myself, whether it’s a man or a dog; they’re the best for every day.” -George Bernard Shaw

All dogs. Every single one you see. From the Rottweiler/Pit Bull beast curled up at my feet, to that annoying Taco Bell Chihuahua, are descended from wolves.  How is that possible?

Ursula Goodenough, over at NPR, has written a piece about genome sequencing in dogs and the evolution of dog breeds.

“Fossil evidence of dog-human cohabitation goes back 30,000 years, and genetic evidence indicates that most modern dogs descend from a wolf —>  dog domestication event that took place in central Asia.

Until recent times, these domesticated dogs were interbreeding “mutts,” moving across the planet with their journeying humans and probably on occasion back-crossing with wild wolves. And then,  some 200 years ago, dog breeding was initiated in England, generating the highly inbred and distinctive lines we encounter today.”
