Is a prior human existence required for a current/subsequent human existence?

If I, this impermanent and suffering and no-self array of aggregates, am journeying through this human realm now, shall I assume that that which was "my prior life", another impermanent and suffering and no-self array of aggregates, was also journeying through the human realm (i.e. a prior human existence is a prerequisite for a subsequent human existence)? I am inclined to think that it is possible for an individual array of ever-fluxuating potentialities to "pass" through the human realm consecutively a number of times.
