Galaxies like our Milky Way can be described in terms of their structure,
dynamics, and stellar populations. Some robust correlations between
galaxy structural properties such as stellar mass, circular velocity,
and size display surprisingly small scatter over many orders of magnitude, 
hinting at well-regulated galaxy formation processes. A major challenge 
to understanding these scaling relations, their tight scatter, and ultimately 
galaxy formation and evolution, is the elusive interplay between visible 
and dark matter. Among others, the radial acceleration relation, concept 
of “galaxy diversity”, intrinsic scatter in galaxy scaling relations,
and comparisons with numerical simulations of galaxy formation are 
analyzed in this context. Our extensive data base of deep galaxy 
rotation curves and multi-band light profiles serves as an ideal 
reference for evolutionary studies of galaxies.
