We explore the reasons for the evolving IR emission of similar galaxies over cosmic time using: 1) Local galaxies from GOALS $(L_{\\rm IR}=10^{11}-10^{12}\\,L_\\odot)$; 2) Galaxies at $z\\sim0.1-0.5$ from the 5MUSES ($L_{\\rm IR}=10^{10}-10^{12}\\,L_\\odot$); 3) IR luminous galaxies spanning $z=0.5-3$ from GOODS and Spitzer xFLS ($L_{\\rm IR}>10^{11}\\,L_\\odot$).
