The way we characterize galaxies and study their evolution in the last two decades, in an statistical way, is to derive integrated, average or characteristic properties and explore the possible relations between them. Those relations are latter interpreted in the frame of scenarios about their cosmological evolution. However, that approach misses the fundamental point that galaxies are resolved entities which evolution may be governed by local rather than global processes. In this talk we explore three different well know global relations that are the reflection of local ones: (i) The star-formation Main Sequence, (ii) The mass metallicity relation and (iii) the Age bimodality. That perspective opens a new view on how galaxies should be studied and understood.
