Right.  However, it is highly unlikely that flight feathers are going to=
 sprout from some theropod's arms, there will have to be a few transitional=
 steps.  From this, we can deduce the existance of contour feathers. =
 Besides, contour feathers are considerably softer than flight feathers, we=
 would expect differing (or no) preservation.
