Spiral galaxies play a fundamental role for our understanding of the now generally adopted cosmology according to which the Universe is dominated by Dark Energy and Dark Matter. An important tool to test predictions of simulations based on this concordance cosmology are so-called scaling relations that link fundamental parameters of spirals like rotation velocity and luminosity (-> Tully-Fisher Relation) or rotation velocity and size. Using deep spectroscopy with the Very Large Telescope and imaging with the Hubble Space Telescope, we have constructed a data set of several hundred spiral galaxies that span more than half the age of the Universe and a variety of environments. With this sample, utilising scaling relations like the Tully-Fisher, I will show how the spiral galaxy population evolved over the past 8 Gyr, how stellar population properties relate to galaxy masses, and how transformations between different galaxy types might occur in galaxy clusters.
