The question of what is the difference between the domestic pig and a wild boar, or the distinction between a broiler chicken and a wild jungle fowl is very similar to the question of what is the difference between a human and a chimpanzee.
Well, maybe. But Evan Ratliff’s piece in National Geographic is an entertaining summary of those distinctions, and of the different possible ways in which they may have come about.
It also reminded me of a great quote from another, much older National Geographic article, which is actually quite relevant again now. ((Not that it was ever not relevant, if you see what I mean.)) Talking about using crop wild relatives, a breeder interviewed by the late Bob Rhoades for The World’s Food Supply at Risk in 1991 says this:
It’s a bit like crossing a house cat with a wildcat. You don’t automatically get a big docile pussycat. What you get is a lot of wildness that you probably don’ t want lying on your sofa.
