Evolution of structure functions is studied in a chiral potential model which incorporates the pion as the chiral symmetry restoring field. Evolution equations for the quark and pion densities are derived in the lowest order at large Q2. The splitting function for quark emission from point-like pion is flavor-dependent. This is shown to lead to nontrivial evolution of the nonsinglet moments in the next order which is consistent with the observed departure from the Gottfried sum rule.
