Hierarchical galaxy
WebGalaxy Diversity Over Time. Studies of galaxy types in galaxy clusters have produced results favouring both the hierarchical and classical models 2. At a time when the universe was 30% younger clusters of galaxies were dominated by many more spiral galaxies 10. Today we see these clusters are dominated by ellipticals.
