Observed redshift evolution of M_dust/M_⋆ in dusty QGs from this work. Individual values are displayed with circles, coloured according to the corresponding D_n4000. Binned medians and associated uncertainties (16th–84th percentile range) are shown with sandy brown circles and lines, respectively. For comparison, with the dashed red line we show the best fit from the stacking analysis of Magdis et al. (2021). The dark grey line and shaded area describe the modelled evolution of ALMA-detected MS galaxies with a functional form of M_dust/M_⋆ ∝ k × (1 + z)^2.5 (Donevski et al. 2020), while the dashed dark grey line shows the shift of 1 dex of this MS scaling relation.
