Thank you for the links!
For purposes of the coursework and to stay most current on what is most scientifically accepted, I teach that about 14,000 years ago is the first strong evidence of domestication from wolf to dog, although there are countless other theories with less evidence.
There are very few things that we learn that involves the past, or nothing that I can think of off the top of my head that is considered “scientific law”, meaning something that is clearly observed and consistent unless we had a time machine.
So questioning the most current and accepted theories are what keeps us from becoming stagnant. It isn’t that long ago that the most accepted scientific theory about the earth is that it was flat. That is why we are here to stay current.
This Wikipedia page is pretty rich with some of the most current “theories” with references for those that like to dive into the rabbit hole:
