Clumps in high-redshift spiral galaxies are smaller than commonly reported, spatially concentrated toward spiral arms, smaller but brighter inside arms than between them, with similar colors, suggesting arms stimulate clump formation but do not alter their star formation properties.

Clumpy galaxies at cosmic noon show systematically lower metallicities than the mass-metallicity relation, with clump properties indicating metal-poor gas accretion as the driver rather than mergers.
Resolved stellar property gradients in Milky Way analog progenitors show inside-out assembly with minor, temporary disruption from major mergers.
