Query: Dynamically Emergent Flavor in a Confining Theory with Unbroken Chiral
  Symmetry   I discuss "truncated" QCD studied recently by Glozman et al. through
numerical simulations. For two flavors it was observed that truncation restores
the full chiral U(2)\times U(2) symmetry of the Lagrangian. Moreover,
additional enhancement of the above symmetry connecting representations with
distinct Lorentz spins was observed. I argue that the chiral symmetry
restoration in a confining theory could entail emergent (extra) dynamical
flavors which would show up in the spectrum of color-singlet particles provided
their mass \neq 0. As an example, I consider truncated QCD with a single
massless Dirac quark. Assuming the validity of the above observations,I
demonstrate how a dynamical SU(2)_{fl} symmetry could emerge for massive spin-1
mesons without contradicting general principles.
