As it was shown in the observations the collisions and mergers of galaxies exert the powerful initiating influence on the star formation on the galactic scales. These processes are accompanied by strong IR emission, OH maser flares and some other manifestation of the galactic activity. As the IR survey depth will increase the number of IR sources on the celestial sphere related to earlier epochs ought to also increase. The possible reason for the change of the IR source statistics is the evolution of the galaxy mass spectrum (GMS).
