  A novel approach for describing the evolution of nucleon structure from the
low-$Q^2$ regime to the high-$Q^2$ asymptotic region is proposed. This
infrared-safe scheme modifies the parton distribution evolution equations to
incorporate the corrections from emergent hadron mass mechanisms and
parton-parton recombination at low $Q^2$. The effective parton mass, generated
by dynamical chiral symmetry breaking, slows the evolution of parton
distributions in the infrared region, causing the DGLAP evolution to freeze
when $Q^2\ll M_{\rm q/g}$. Notably, this scheme renders the high-$Q^2$ parton
distributions insensitive to the choice of input hadronic scale. The
parton-parton recombination effect is crucial in suppressing the rapid growth
of parton distributions at small $x$, consistent with experimental data. When
applied to three valence quark distributions derived from a quark model, our
scheme yields parton distributions that agree well with deep-inelastic
scattering data in both large-$x$ and small-$x$ regions, providing a unified
description of nucleon structure across the entire $Q^2$ range.
