The star formation is an internal process transforming cold and dense cores of molecular clouds to stars. It may be triggered internally by expanding shells, or externally, e. g. by galaxy collisions. The gas accretion and galaxy merging events are external contributors to galaxy evolution. They compete with another internal process of galaxy evolution, which is the secular evolution redistributing the mass and angular momentum inside of galaxies as a consequence of bar and spiral arms formation. Stripping of ISM in galaxy clusters is reviewed as another example of interaction of galaxies with their environment.
