Relative evolution of the numbers of candidate quiescent galaxies (blue), DSFGs (purple), and LRDs (red) in the redshift interval z = 1.5–5.5 vs. redshift. For the quiescent galaxies and DSFGs, we only show those with stellar masses M_* > 10¹⁰ M_⊙. The DSFGs show all >3σ ALMA sources, and the quiescent galaxies correspond to the strict selection.
