Evolution is a product evaluation. Hereditary can give you an eye color and your child a different eye color, and so forth down the genetic line, within a pool of possible colors available to your Punnett square. Evolution would be a shift from this system to one where, for example, eye color is always blue for a specific, collective reason.

I would argue that's not evolution as it loses the true sense of what qualifies an environmental condition as "important" to foster or compensate for, the weights and checks of growing genetics, but an all too easy counter-argument is that humans
are the environment to which response is being given. All that matters, I guess, outside of the realm of morality, is whether two tame silver foxes, in breeding, reliably produce what will functionally be a tame silver fox kit.
