We explore the possibility that the observed pattern of quark masses is the
consequence of a statistical distribution of Yukawa couplings within the
multiverse. We employ the anthropic condition that only two ultra light quarks
exist, justifying the observed richness of organic chemistry. Moreover, the
mass of the recently discovered Higgs boson suggests that the top Yukawa
coupling lies near the critical condition where the electroweak vacuum becomes
unstable, leading to a new kind of flavor puzzle and to a new anthropic
condition. We scan Yukawa couplings according to distributions motivated by
high-scale flavor dynamics and find cases in which our pattern of quark masses
has a plausible probability within the multiverse. Finally we show that, under
some assumptions, these distributions can significantly ameliorate the runaway
behavior leading to weakless universes.
