The current cosmological paradigm postulates that galaxies assembled
hierarchically by the aggregation of smaller systems. The formation
history of galaxies such as the Milky Way involves infall, mergers and
interactions with different relative importance probably modulated by the
global environment where they inhabit. These mechanisms might leave
fingerprints or signatures in the stellar populations which could provide
insight in their history of formation. In particular, chemo-dynamical
patterns are a challenging route to confront models and observations.
State-of-art cosmological codes include chemo-dynamical schemes which
allow the description of the non-linear evolution of the structure
together with the chemical enrichment of baryons. These models are
powerful tools to understand observations in the near and high redshift
universe within the current cosmological framework. In the review, I will
present the main success and open questions of the current cosmological
models in the quest to understand the formation of the Milky Way-type
galaxies.
