Younger galaxies haven't. The Magellanic clouds are full of young stars, so aren't they young galaxies? YouRang, don’t you mean older galaxies have had time to gorge on their neighbours?

I.e. presumably older galaxies have had less time to gorge on their neighbors and should be less massive. (Indeed the most ancient galaxies look like replicas of the Magellanic clouds.)
