The other day I happened to be sitting in the barbershop waiting my turn and perusing a copy of National Geographic with a picture of a Fox on the cover. I have been seeing a red fox visit my gardens since before the snow began to melt so I began to leaf through the article and discovered that researchers in Russia have successfully domesticated the silver fox. What's more they have been able to show that the domestication is the result of genetic breeding for specific traits rather than due to nurture.
It turns out that this research has been ongoing for as long as I have been on the planet, maybe longer. Generation after generation has been bred either for positive or negative response to the presence of humans and behavior which once was the specialty of a few species like dogs and cats, farm animals and perhaps some lab rats, has now been observed in species which were previously resistant to domestication such as wolves and foxes.
After reading this I had a bit of mental flatulence and a cloud of thoughts escaped me in a moment of enlightenment.
