That's way too low. It's somewhere in the 19-32k year range: http://www.the-scientist.com/?articles.view/articleNo/38279/...

I have read numerous different accounts. It appears that the selective breeding of different breeds is actually much shorter even than 5,000 years. Most breeds are less than 1,000 years old.
