Thanks for that! The interesting part of the article is that they only bred “friendly” foxes to each other over 50 years to get offspring that had that genetic trait. Their physical appearance also changed over 50 years so that they no longer resembled wild foxes. Fifty years is a lot of generations in fox life span. Most wild animals that are raised in captivity aren’t raised that way. They are just plucked out of the wild with no consideration to personality traits. I’m sure it would make a big difference if they were bred over several generations by selective breeding. Even domestic dogs can be bred that way to insure that only the best traits are passed on to future generations. Unfortunately, not all breeders are good breeders.
