We present results from numerical simulations of full, two flavor QCD therm
odynamics at N-t = 4 with domain wall fermions. For the first time a numeri
cal simulation of the full QCD phase transition displays a low temperature
phase with spontaneous chiral symmetry breaking but intact flavor symmetry
and a high temperature phase with the full SU(2) x SU(2) chiral flavor symm
etry.
