How are there so many different breeds of dog, when they all must have origninated from the same breed?

Answer 1

Because they didn't originate from a breed, they originated from wolves and other native species of wild dogs.

Breeding different wolves/jackals/dingoes and whatever result in slightly different looking dogs. Dogs possessing certain traits are selected for further breeding in order to 'bring out' that trait in a breed. Over many, many generations of doing this 'selective breeding' (this has been going on for thousands of years) you end up getting dramatically different looking dogs - our modern dog breeds
