Deciphering the Hubble Tuning ForK: Now and at High Redshifts

The key issue in understanding the galaxy evolution is to predict the evolution of the

Hubble fork with redshift --- this goal is still elusive as we do not even understand

the distribution of morphological galaxy types in the contemporary universe. Morphology 

of disk galaxies is dominated by the presence or absence of galactic bars. At present, 

the origin of these bars is an enigma, nor we can predict their properties. Observations

also exhibit tension: are these bars a local phenomenon or are a resilient cosmological

features? What is the role of bars in the evolution of disk-halo systems? In my talk,

I shall present new results which strongly favor the cosmological origin of galactic bars,

and analyze their role as mediators in the baryonic and dark matter co-evolution as 

strongly nonlinear physical systems driven by resonances.
