Gauge-invariant equations describing the evolution of the potential perturbations of the critical density in an isotropic Universe filled with a dissipative gas medium are derived in the gravitational stability theory. The equations are shown to reduce to the singularly perturbed third-order equation nonlinear in a series of parameters, which determines the bifurcation properties of its solutions. Near the singular point, the dynamic stability breakdown, with accompanying anomalous growth of the density clots which have rather small peculiar velocities. This effect is interpreted as a generation of the dissipative structure in an expanding universe. The effect of cold dark matter on the nonequilibrium phase transition in the baryon subsystem is evaluated.
