We present a study of the inclusive production of pi0, eta, K(s)0 and
LAMBDA based on 929,000 hadronic Z decays recorded with the L3 detecto
r at LEP. The measured inclusive momentum distributions have been comp
ared with predictions from parton shower models as well as an analytic
al Quantum Chromodynamics calculation. Comparing to low energy e+e- da
ta, we find that QCD describes the energy evolution of the hadron spec
trum.
