  Fermion masses and mixing, both in the quark and leptonic sector, are
discussed within the approach to the Yukawa puzzle proposed by Arkani-Hamed and
Schmaltz. In the quark sector we have shown that at least two extra dimensions
are necessary in order to obtain sufficient CP violation, while reproducing the
correct quark mass spectrum and mixing angles. We have also studied the
consequences of suppressing lepton number violating charged lepton decays
within this scenario for lepton masses and mixing angles.
