Given the wide variety of dog breeds we have now — from the Great Dane to the Chihuahua — we can be tempted to think that perhaps they came from different parents.
Well, what do you know? Based on a research, the origin of our domestic pooch from wolves has been established. After the researchers examined the mitochondrial DNA sequence variation among 654 domestic dogs representing all major dog populations the world over, the results suggested that all dog populations are of the same origin from a single gene pool. This means even your poodle or your pit bull at home is related to the wolves in the wilderness.
Believe it or not, whatever dog breed you see out there, they all came from the same parents that boarded Noah’s ark a few thousand years ago.
