A question regarding evolution.
I was watching a program the other day that was discussing the latest theory on how wolves had become dogs. During this program they mentioned an experiment in Russia where foxes had been selected and bred for tamability. They said that when this was done there were physical changes in the foxes as well, such as changes in coloration, the ears became floppy, and other changes in behaviors such as barking and answering to a name (I would guess this is a change in 'intelligence'(?)). The foxes went through fairly drastic changes in a very short time period. My question is, if all these behaviors, and especially the morphological changes, are expressions of different genes, then how do they relate to the sole selection criteria of tameability? In populations, is it normal that we find that individuals with like temperaments (or any single selection criteria) normally have other common traits? Can we say "Look at so and so's eyes, he must be one mean bastard" (hypotheitcally)?
