The approach to the chiral limit in full QCD is investigated with a blocked Wilson fermionic action. Finite size effects prohibit taking the chiral limit on small lattices. We find that various observables expected to be influenced by chiral and finite temperature properties of the theory reveal patterns which suggest a transition to chiral-symmetry restoration and deconfinement to be the origin of the observed phenomena.
