I'm sorry Ray, but you'll need to be more careful with your terms
here, or else what you're saying is close to meaningless. What
*exactly* do you mean by "stress" -- uncomfortable living
conditions, bad food, crossbreeding -- all of the above?
If so, are you then claiming that these conditions *cause
mutations*, and in particular the alleged "common mutation" that
results in neoteny? This appears to be what you are claiming,
but it's hard to be sure. In particular, what does "genetic
stress" mean?

The point is that the environment is the *same* for those not
selected for breeding for purposes of this experiment. The
unselected foxes were not prevented from mating. To be sure, the
experimenters created artificial selection pressure, but that has
nothing in particular to do with mutations. So let me repeat my
first question: To your knowledge, has anyone yet associated
neoteny or domestication with a particular mutation?
