I report the results of numerical simulations of protogalaxy evolution, which show that the gas-rich disk of a young galaxy becomes gravitationally unstable and fragments into massive dumps of subgalactic size. Most of the stars are formed in these discrete dumps, thereby providing a natural explanation for the peculiar morphology of high-redshift galaxies. The dynamical evolution of these young systems is dominated by the dumps and ultimately leads to structures resembling present-day galaxies, with a spheroidal bulge and an exponential disk. I interpret the differences between the Hubble types of galaxies as resulting from different timescales of disk formation. Finally, the model provides a causal link between the emergence of quasar activity and the dynamical evolution of the host galaxy.
