In studying the dynamics of large N_c, SU(N_c) gauge theory at finitetemperature with fundamental quark flavours in the quenched approximation, weobserve a first order phase transition. A quark condensate forms at finitequark mass, and the value of the condensate varies smoothly with the quark massfor generic regions in parameter space. At a particular value of the quarkmass, there is a finite discontinuity in the condensate's vacuum expectationvalue, corresponding to a first order phase transition. We study the gaugetheory via its string dual formulation using the AdS/CFT conjecture, the stringdual being the near-horizon geometry of N_c D3-branes at finite temperature,AdS_5--Schwarzschild X S^5, probed by a D7-brane. The D7-brane has topology R^4X S^3 X S^1 and allowed solutions correspond to either the S^3 or the S^1shrinking away in the interior of the geometry. The phase transition representsa jump between branches of solutions having these two distinct D-branetopologies. The transition also appears in the meson spectrum.Comment: 13 pages, three multi-component eps figures, LaTeX (V2: refs added,  figs improved. V3: refs added, discussion of meson spectrum improved
