Abstract: The cosmic concordance model (LCDM) has become the standard theory of cos- mological structure formation, within which cosmological measurements are confronted and interpreted. Although its predictions appear to be in good agreement with data on large scale structure, a number of discrepancies with data emerges on the galactic and sub-galactic scales.

In this talk I will show the distribution of dark matter in late Hubble type galaxies and, in particular, in the spiral galaxy NGC 3198. I will also address the key challenges of galaxy formation and evolution in the LCDM scenario by means of the kinematics of a sample of dwarf disk galaxies. Finally I will speak about the universal rotation curve of dwarf disk galaxies, which are crucial objects in testing the LCDM scenario. 1
