No 'new functions'
Faith writes:
If the mutation occurs in a fur color gene it will only affect fur color. You are not going to get anything really new, a new function for instance, through mutation.
So fur colour can change, but we shouldn't expect any new functions--like, say, the ability to sneak up on prey unobserved (polar bears, tigers)?
How about fur stiffness? Can that change, too? Or would the change get too newly functional (hedgehogs)?
If hair shafts can change shape, how about skeletal features?
You postulate a natural boundary where ongoing small mutations must suddenly stop happening. Why must they stop? Where may a geneticist look for this border?
