Man that just straight up spooky...

.. my foggy brain seems to remember something called symbiosis, or "learned dependant interaction between different species"....
Defentitely appears to be a similar story to that of the domestication of the dog...
... I'd try givin' the yote a que as you come on the ranch(horn, whistle, etc.) and leaving a "reward hog" each time...
Has the yote showed up at the catch yet???
Very cool.
