  We report on numerical simulations of SU(2) lattice gauge theory with two
flavors of light dynamical quarks in the adjoint of the gauge group. The
dynamics of this theory is thought to be very different from QCD -- the theory
exhibiting conformal or near conformal behavior in the infrared. We make a high
resolution survey of the phase diagram of this model in the plane of the bare
coupling and quark mass on lattices of size 8^3 \times 16. Our simulations
reveal a line of first order phase transitions extending from beta=0 to
beta=beta_c \sim 2.0. For beta > beta_c the phase boundary is no longer first
order but continues as the locus of minimum meson mass. For beta > 2.0 we
observe the pion and rho masses along the phase boundary to be light,
independent of bare coupling and approximately degenerate. We discuss possible
interpretations of these observations and corresponding continuum limits.
