Young stellar populations (YSPs) are present in 30--50% of all radio source host galaxies in the local Universe. The analysis of high-quality spectra of the YSPs demonstrates that they comprise post-starburst populations that are relatively old (0.05--2.5Gyr) and massive (1×109 < MYSP < 2×1010 M&sun;), representing a significant proportion (1--50%) of the total stellar mass in the regions sampled by the spectroscopic slits. These results are consistent with the idea that radio sources are triggered in major galaxy mergers, but relatively late in the merger sequence, following a starburst phase in which the host galaxies appear as luminous or ultraluminous infrared galaxies (LIGs, ULIGs). Thus, the nearby radio galaxies with YSPs form a subset of the population of early-type galaxies that is evolving most rapidly in the local Universe.
