Understanding the high redshift sub-mm luminous population and the
relation to other galaxy populations

A large sample of sub-mm sources with optically faint
counterparts have been obtained through a radio pre-selection technique.
Through modeling of this population in radio/sub-mm color spaces, and
comparison with blank field samples, we have constrained their
evolutionary properties. The implications for the general sub-mm source
population and the relation of the SCUBA detected Lyman-break galaxies are
presented.
