  The Standard Model flavor structure can be explained in theories where the
fermions are localized on different points in a compact extra dimension. We
show that models with two bulk scalars compactified on an orbifold can produce
such separations in a natural way. We study the shapes and overlaps of the
fermion wave functions. We show that, generically, realistic models of Gaussian
overlaps are unnatural since they require very large Yukawa couplings between
the fermions and the bulk scalars. We give an example of a five dimensional two
scalar model that accounts naturally for the observed quark masses, mixing
angles and CP violation.
