More like, those wolves who could amiably be around humans got fed, and thus had a higher survival rate, while those wolves which acted in a hostile manner towards humans had a much lower survival rate.
It was the smart wolves...the adaptable wolves who made the transition.
The alpha males took a back seat and the adaptable wolves moved ahead.
Hence the needy, approval seeking wolves we see today in our dogs.
We love them but they are the ass-kissers of yesteryear.
