  Texture zeros in the quark Yukawa matrices generally lead to precise and
simple expressions for CKM matrix elements in terms of ratios of quark masses.
Using the new data on $b-$decays we test a particularly promising texture zero
solution and show that it is at best approximate. We analyse the approximate
texture zero structure and show it is consistent with experiment. We
investigate the implications for the CKM unitarity triangle, measurements at
$BaBar$ and $BELLE$ as well as for the theories which invoke family symmetries.
