We analyse the metallicity histories of ~4,500 galaxies from the GAMA surveyat z<0.06 modelled by the SED-fitting code ProSpect using an evolvingmetallicity implementation. These metallicity histories, in combination withthe associated star formation histories, allow us to analyse the inferredgas-phase mass--metallicity relation. Furthermore, we extract themass--metallicity relation at a sequence of epochs in cosmic history, to trackthe evolving mass--metallicity relation with time. Through comparison withobservations of gas-phase metallicity over a large range of redshifts, we showthat, remarkably, our forensic SED analysis has produced an evolvingmass--metallicity relationship that is consistent with observations at allepochs. We additionally analyse the three dimensional mass--metallicity--SFRspace, showing that galaxies occupy a clearly defined plane. This plane isshown to be subtly evolving, displaying an increased tilt with time caused bygeneral enrichment, and also the slowing down of star formation with cosmictime. This evolution is most apparent at lookback times greater than 7 Gyr. Thetrends in metallicity recovered in this work highlight that the evolvingmetallicity implementation used within the SED fitting code ProSpect producesreasonable metallicity results over the history of a galaxy. This is expectedto provide a significant improvement to the accuracy of the SED fittingoutputs.
