Just read an article about a Russian fur farm that began selective breeding of foxes soley for the trait of tameness. In 50 years they have foxes that like to be petted, wag their tails, do not attack or run away and have droopy ears. They are in a variety of colors, including white with black ears and tails. There is word on another site that they may be given a separate subspecies status. They have been available in the foreign pet trade for a decade now. Don't know if any have been brought to the US. I can see that there could be some bucks to be made with breeding these kits. (not me, I just have an academic interest) Keep in mind that all hamsters in the world were wild before 1933. Gerbils in 1964. (there are genetic lines of skunks that have been selectively raised for over 150 years, even red ones) At what point do animals become recognized as domestic vs wild?
along the same lines, scientists in Europe have been selectively breeding cattle to retro engineer an Auroch, a giant wild forest bovine that once roamed Europe. Last documented kill was in the 17th century. A press release last week indicated they are getting close to actually producing these giant cattle. Those things are thought to have weighed 3500 to 4000 thousand pounds and stood 6.5 ft tall at the shoulder. Not sure how controllable such a thing would be.
Brings to mind the old commercial, it's not nice to fool mother nature.
