  Based on a complete set of $J = 0$ and $J=1$ spatial isovector correlation
functions calculated with $N_F = 2$ domain wall fermions we identify an
intermediate temperature regime of $T \sim 220 - 500$ MeV ($1.2T_c$--$2.8T_c$),
where chiral symmetry is restored but the correlators are not yet compatible
with a simple free quark behavior. More specifically, in the temperature range
$T \sim 220 - 500$ MeV we identify a multiplet structure of spatial correlators
that suggests emergent $SU(2)_{CS}$ and $SU(4)$ symmetries, which are not
symmetries of the free Dirac action. The symmetry breaking effects in this
temperature range are less than 5%. Our results indicate that at these
temperatures the chromo-magnetic interaction is suppressed and the elementary
degrees of freedom are chirally symmetric quarks bound into color-singlet
objects by the chromo-electric component of the gluon field. At temperatures
between 500 and 660 MeV the emergent $SU(2)_{CS}$ and $SU(4)$ symmetries
disappear and one observes a smooth transition to the regime above $T \sim 1$
GeV where only chiral symmetries survive, which are finally compatible with
quasi-free quarks.
