In the earliest stages of the evolution of low-mass young stellar objects, the central star and disk are deeply embedded in a large envelope of gas and dust. The Submillimeter Array is excellent for studies of these earliest embedded stages: the high angular resolution resolve the innermost regions of the envelopes and even the circumstellar disks. The high excitation transitions of many common molecular species in the submillimeter likewise probe warm and dense gas and thereby constrain the dynamics and chemistry in the innermost (< 200 AU) regions of the protostellar envelope. In this talk I will present a brief overview of results from programs studying the deeply embedded stages of low-mass protostellar evolution with the Submillimeter Array.
