We use published reconstructions of the star formation history (SFH) of theLarge Magellanic Cloud (LMC), Small Magellanic Cloud, and NGC 300 from theanalysis of resolved stellar populations to investigate where such galaxiesmight land on well-known extragalactic diagnostic plots over the galaxies'lifetime (assuming that nothing other than their stellar populations change).For example, we find that the evolution of these galaxies implies a complexevolution in the Tully-Fisher relation with lookback time and that the observedscatter is consistent with excursions these galaxies take as their stellarpopulations evolve. We find that the growth of stellar mass is weighted toearly times, despite the strongly star-forming current nature of the threesystems. Lastly, we find that these galaxies can take circuitous paths acrossthe color-magnitude diagram. For example, it is possible, within theconstraints provided by the current determination of its SFH, that the LMCreached the red sequence at intermediate age prior to ending back up on theblue cloud at the current time. Unfortunately, this behavior happens atsufficiently early times that our resolved SFH is crude and insufficientlyconstraining to convincingly demonstrate that this was the actual evolutionarypath. The limited sample size precludes any general conclusions, but we presentthese as examples how we can bridge the study of resolved populations and themore distant universe.
