This was directed evolution (human directed breeding) as opposed to the more random form. But very interesting – especially since the selection was made only for behavior but the result was a group of foxes that had not only behavioral differences, but also differences in appearance and smell.[/quote]
Interesting. I wonder if the more docile and sociable foxes from the original group had very slight, imperceptible differences with respect to these traits.[/quote]
That’s the assumption. You can see it in golden retrievers (who seem to have been bred almost to a clone army of friendly pets) to pit bulls, who’ve been bred in the other direction. I believe the emotional responsiveness of any creature (including humans) has a large genetic element.
