description Precise measurements and calculations of the internal structure of hadronic jets produced in high energy proton or lead collisions have become a prominent research area in recent years. Jet substructure provides information about quantum chromodynamics (QCD) and plays an important role in the study of the evolution of the quark-gluon plasma. The ALICE experiment is uniquely suited to provide insight into the smallest splitting angles due to high efficiency in the reconstruction of charged particles. In this proceeding, we present an overview of recent ALICE results on jet substructure in pp collisions involving measurements of generalized angularities of groomed and inclusive jets, a new double-differential measurement of the Lund jet radiation plane for jets with a transverse momentum ($p_{\mathrm{T}}$) between 20 and 120 GeV/$c$, the first direct measurement of the dead-cone effect, and substructure measurements of heavy flavor tagged jets. These latest results provide new insights into the jet evolution by comparing to various theoretical predictions.
