Evolution of the fraction of galaxies with substructures (left panel) and clumps (middle panel) detected with the intrinsic detection approach as a function of redshift for different regions of the M_★ − SFR plane, as illustrated in the right panel with circles of a different color, line style, and thickness. We use the same redshift bins spanning 1 Gyr of cosmic time as in Figs. 2 and 3. Each circular region has a radius of 0.2 dex and the regions are chosen to evenly map the plane. We only show regions with more than ten galaxies in all redshift bins and lines are slightly offset vertically to improve readability.
