We report full QCD simulations on a 16^34 lattice. For two degenerate flavors no finite-temperature phase transition is found for quark masses of ma=0. 01 and 0. 025, where a is the lattice spacing, while for three degenerate flavors a first-order transition is easily seen for ma=0. 025. Nature, with nearly massless up and down quarks and one heavier strange quark, lies between these two cases. For mₔ, da=0. 025 and mₒa=0. 1 we find that m₊/m_=0. 46 (1) and that no transition occurs, calling into question the existence of a QCD phase transition.
