Where did the domestication of dogs start

According to Dr. Bruce Fogle's book "If your dog could talk...", here's a timeline I've created.

45,000 years ago - genetic evidence shows that the original adaptation have occurred this early in east Asia

15,000 years ago - archaeological evidence confirms it started from this point forward

14,000 years ago - people who migrated across the Bering Island bridge brought their dogs with them (which means that that the dog's ancestry probably originated from a small group of Asian wolves)

200 - 300 years ago - a vast majority of the 400 recognized breeds were created during this time

I hope this helps.
